Changelog
4.6.0 (Feature release)
We’ve updated the disabled state of Text Input, Textarea, Select and File Upload components so it is consistent across browsers and devices. They’re also now consistent with the existing disabled styles for Buttons, Checkboxes, and Radios.
Disabled form controls appear at 50% opacity and with an alternative cursor appearance when hovered over.
This was added in pull request #3187: Add disabled styles for form controls.
disabled
parameter to form controlsWe’ve updated the Nunjucks macros for Text Input, Textarea, Select and File Upload components to include a top-level disabled
parameter. This will make it easier to enable the disabled state for these controls.
{{ govukInput({
id: "disabled-input",
name: "disabled-input",
value: "Unchangeable value",
disabled: true
}) }}
Disabled form controls have poor contrast and can confuse some users, so avoid them if possible.
Only use disabled form controls if research shows it makes the user interface easier to understand.
This was added in pull request #3187: Add disabled styles for form controls.
By default, when a user leaves a page, the Accordion will remember the layout of expanded and collapsed sections selected by the user. If the user returns to the page, this layout will be restored and override any sections manually set as expanded in code.
You can now disable this functionality by using the rememberExpanded
option in the govukAccordion
Nunjucks macro.
If you're not using the Nunjucks macro, you can disable it using the data-remember-expanded
HTML attribute.
This was added in pull request #3342: Add option to disable sessionState in Accordion.
id
parameter to ButtonsWe’ve updated the Button Nunjucks macro to include an optional id
parameter.
{{ govukButton({
text: "Save and continue",
id: "continue-button"
}) }}
This was added in pull request #3344: Adding optional ‘id’ attribute to button component.
Thanks to Tom Billington for this contribution.
We've added a new .govuk-input--extra-letter-spacing
class for Text Input. This increases readability of text inputs that receive sequences of digits (like security codes, references or phone numbers).
You can add it through the classes
option when using Nunjucks, or directly in the class
attribute of the <input>
when using HTML.
This was added in pull request #2230: Add extra letter spacing modifier for inputs
init
methodWe have deprecated all of the JavaScript properties in the API, except for the init
method for each component. We'll make all of the deprecated JavaScript properties private in our next main release.
Please let us know if you're using parts of the API other than the init
method by filling in this form. We'll use this information when prioritising future additions to the public API.
This was added in pull request #3499: Deprecate all JavaScript instance properties the except init
method.
.govuk-button--disabled
class on buttonsWe have deprecated the .govuk-button--disabled
class and will remove it in the next major release.
If a Button uses a <button>
or <input>
element, use the disabled HTML attribute instead.
You will not need to make any changes if you're using the govukButton
Nunjucks macro.
Disabling links that are styled to look like buttons will not be supported by future releases.
This was added in pull request #3326: Deprecate govuk-button--disabled
class.
The next main release of GOV.UK Frontend will remove support for Internet Explorer 8 (IE8). In preparation for this, we've deprecated the settings and mixins used when generating IE8 specific stylesheets.
You'll start seeing deprecation warnings if you're:
govuk-if-ie8
and govuk-not-ie8
mixins in your own Sass code (for example @include govuk-if-ie8
)$govuk-is-ie8
and $govuk-ie8-breakpoint
settings to anything other than their default valuesIf you no longer need to support IE8, we recommend you stop generating an IE8 specific stylesheet and remove references to the IE8 mixins from your code.
You can also silence these deprecation warnings by adding ie8
to the $govuk-suppressed-warnings
setting, but once we’ve released v5.0 you will need to address them as part of the upgrade process.

4.5.0 (Feature release)
You can now use the summary card. This new variant of the Summary list component can help you:
This was added in pull request #2931: Add summary card enhancement to summary list.
We've updated the Accordion component to use the new hidden="until-found"
attribute value.
This allows the browser's native 'find in page' functionality to search within and automatically open sections of the accordion. Currently, this functionality is only supported by recent versions of Google Chrome, Microsoft Edge and Samsung Internet.
This was added in pull requests:
hidden='until-found'
.js-enabled
page loadYou can now use source maps to help identify errors and console messages from GOV.UK Frontend precompiled files.
This was added in pull request #3023: Add source maps to compiled JavaScript and CSS.
We've fixed errors in IE8 caused by updates to our precompiled JavaScript. The issue prevented some polyfills from running, but was limited to the release-v4.4.1.zip
and release-v4.4.0.zip

For non-GOV.UK branded websites, you can now change the Button component background and text colour.
To change the Button component background colour, set the $govuk-button-background-colour
Sass variable.
To change the Button component text colour, set the $govuk-button-text-colour
Sass variable.
@import "node_modules/govuk-frontend/govuk/base";
$govuk-button-background-colour: govuk-colour("yellow");
$govuk-button-text-colour: govuk-colour("black");
@import "node_modules/govuk-frontend/govuk/components/button/index";
This was added in pull request #2752: Change the Button component background and text colour. Thanks to Nick Colley for this contribution.
When using the header Nunjucks macro, you can now translate the text of the mobile navigation menu toggle button by using the menuButtonText
parameter.
You should avoid lengthy values for the menuButtonText
parameter. If the text is too long it can overflow and cause visual issues.
This was added in pull request #2720: Add parameter to localise mobile menu toggle button.
When using the character count Nunjucks macro, you can now translate the description of textarea by using the textareaDescriptionText
option.
This text is announced by screen readers when the character count input is focused. It's also displayed visually as a fallback if JavaScript is not available.
This was added in pull request #2742: Add ability to customise character count fallback text, and the option renamed to textareaDescriptionText
in pull request #2915.
You can now translate the text shown by the character count component to inform users of:
The Nunjucks macro accepts new options so you can customise each message. You can:
charactersAtLimitText
or wordsAtLimitText
to provide the text that shows when users have reached the limit.charactersUnderLimitText
or wordsUnderLimitText
to provide the text that shows when users are under the limit. The component will pluralise the message according to the configured locale and the number of characters or words remaining.charactersOverLimitText
or wordsOverLimitText
to provide the text that shows when users are over the limit. The component will pluralise the message according to the configured locale and the number of characters or words remaining.You'll find guidance about the plural forms in our documentation about localising GOV.UK Frontend. The component will replace %{count}
with the number of characters over or under the limit.
If you're not using Nunjucks macros, you can use data-* attributes to provide these translations. Within the attribute value, any quotation marks or other characters reserved by HTML needs to be converted into their HTML entity equivalents.
You can:
data-i18n.characters-at-limit
or data-i18n.words-at-limit
for when users are at the limitdata-i18n.characters-under-limit.{other,many,few,two,one,zero}
or data-i18n.words-under-limit.{other,many,few,two,one,zero}
, with one suffix for each plural form required by your localedata-i18n.characters-over-limit.{other,many,few,two,one,zero}
or data-i18n.words-over-limit.{other,many,few,two,one,zero}
, with one suffix for each plural form required by your localeYou can also provide these messages using a JavaScript configuration object when creating an instance of the component or initialising all components. See our guidance on localising GOV.UK Frontend for how to do this.
This was added in the following pull requests:
When configuring the character count's limit in JavaScript, you can customise the description provided to assistive technologies when users focus the input (so it indicates the overall limit of characters or words).
Depending on the plural form required by your locale, you can pass the description in the HTML using the data-i18n.textarea-description.{other,many,few,two,one,zero}
attribute on the element to provide the text to set as the description.
You can also provide these messages using a JavaScript configuration object when creating an instance of the component or initialising all components. See our guidance on localising GOV.UK Frontend for how to do this.
This was added in pull request #2915.
You can now translate the text of the accordion component's show and hide toggle buttons.
When using the Nunjucks macro, you can use the new showSectionText
and hideSectionText
parameters to customise the text of the 'show' and 'hide' toggles in each section.
You can also use showAllSectionsText
and hideAllSectionsText
parameters to customise the text of the toggle at the top of the accordion.
If you're not using the Nunjucks macro, you can customise these using data-* attributes. Within the attribute value, any quotation marks or other characters reserved by HTML needs to be converted into their HTML entity equivalents.
data-i18n.show-section
data-i18n.show-section-aria-label
data-i18n.hide-section
data-i18n.hide-section-aria-label
data-i18n.show-all-sections
data-i18n.hide-all-sections
You can also change this text for all instances of the Accordion using a JavaScript configuration object. See our guidance on localising GOV.UK Frontend for how to do this.
This was added in pull requests:
You can now suppress warnings from deprecations within GOV.UK Frontend by updating the $govuk-suppressed-warnings
map in Sass. Every deprecation warning will now include a warning "key" which you can use in the following code, placed at the root of your sass project:
$govuk-suppressed-warnings: (
deprecated-feature
);
This was added in #2911 Add warning suppression functionality
JavaScript components can get the same configuration options in 2 ways - through data attributes, as before, and now when creating an instance. These components are:
Button
component, for its preventDoubleClick
option (matching data-prevent-double-click
)CharacterCount
component, for its maxlength
, maxwords
and threshold
options (matching data-maxlength
, data-maxwords
and data-threshold
, respectively)ErrorSummary
component, for its disableAutoFocus
option (matching data-disable-auto-focus
)NotificationBanner
component, for its disableAutoFocus
option (matching data-disable-auto-focus
)You can leave out these configuration options when using the Nunjucks macro and provide configuration when:
initAll
For example:
// Creating a single instance
var button = document.querySelector('[data-module="button"]')
new GOVUKFrontend.Button(button, {preventDoubleClick: true})
// Or initialising components in bulk
GOVUKFrontend.initAll({
button: {
preventDoubleClick: true
}
// Or, for the other components,
// characterCount: {/* options */},
// errorSummary: {/* options */},
// notificationBanner: {/* options */}
})
You can find more information about component configuration in GOV.UK Frontend documentation.
This was added in pull requests specific for each components:
If you're not using the Nunjucks macros, you can improve the experience for screen reader users by making these changes to the error summary markup:
aria-labelledby="error-summary-title"
and role="alert"
from the parent element (govuk-error-summary
)div
wrapper around the contents of govuk-error-summary
with the attribute role="alert"
id="error-summary-title"
from the error summary h2
(govuk-error-summary__title
)This will enable screen reader users to have a better, more coherent experience with the error summary. It will make sure users of JAWS 2022 or later will hear the entire contents of the error summary on page load and therefore have further context on why there is an error on the page they're on.
This was added in pull request #2677: Amend error summary markup to fix page load focus bug in JAWS 2022.
In GOV.UK Frontend v5.0 we will stop supporting compatibility with legacy codebases. We are therefore deprecating the compatibility mode variables associated with legacy codebases:
$govuk-compatibility-govukfrontendtoolkit
$govuk-compatibility-govuktemplate
$govuk-compatibility-govukelements
This was introduced in pull request #2882: Deprecate compatibility mode settings.
In GOV.UK Frontend v5.0 we will stop supporting compatibility with legacy codebases. As part of this, we're deprecating settings controlled by compatibility mode variables. This includes the govuk-compatibility
mixin and the following settings:
$govuk-use-legacy-palette
$govuk-use-legacy-font
$govuk-typography-use-rem
$govuk-font-family-tabular
This was introduced in pull request #2844: Remove compatibility mode from govuk-frontend.
In pull request 2851: Support Prototype Kit v13 we've introduced support for the plugins system included in the upcoming Prototype Kit v13.
We've made fixes to GOV.UK Frontend in the following pull requests:
Changelog
4.3.1 (Patch release)
govuk-!-margin-static
and govuk-!-padding-static
classesWe've fixed an error in the naming convention of the static spacing override classes we'd introduced in v4.3.0. These classes should start with govuk-!-static
, and we've now deprecated the incorrect classes.
If you're using the static spacing margin override classes, replace any classes starting with govuk-!-margin-static
with govuk-!-static-margin
. For example: govuk-!-margin-static-2
would become govuk-!-static-margin-2
.
If you're using the static spacing padding override classes, replace any classes starting with govuk-!-padding-static
with govuk-!-static-padding
. For example: govuk-!-padding-static-2
would become govuk-!-static-padding-2
.
We've deprecated the govuk-!-margin-static
and govuk-!-padding-static
classes, and will remove them in a future major release.
This change was introduced in pull request #2770: Fix ordering of properties in static spacing override classes. Thanks to @garrystewart for reporting this issue.

You can now customise the Open Graph image URL included in the head
by setting the opengraphImageUrl
Nunjucks option.
Also, the default Open Graph image URL meta tag will now only be included if you set the either opengraphImageUrl
or assetUrl
.
This was added in pull request #2673: Allow Open Graph image URL to be customised.
When using the footer Nunjucks macro, you can now translate the text of the Open Government Licence (OGL) and Crown copyright statements using the contentLicence
and copyright
parameters.
Visit The National Archives' documentation on OGL and Crown copyright for information on what you need to include in these statements.
This was added in pull request #2702: Allow localisation of content licence and copyright notices in Footer.
If using the Nunjucks macros, you can now pass HTML content directly into compatible components using the Nunjucks call syntax. If HTML is provided through the call syntax, the nunjucks macro will ignore the HTML and text options.
Components updated to support this syntax are:
descriptionHtml
parameter)This was added in pull request #2734: Update various components to be callable.
You can now use static spacing override classes to apply spacing from the static spacing scale to elements of your design.
The new classes start with: govuk-!-static-
followed by either margin-
or padding-
, and then a spacing unit number.
To apply spacing in a single direction, include left-
, right-
, top-
, or bottom-
just before the spacing unit.
For example:
govuk-!-static-margin-9
will apply a 60px margin to all sides of the element at all screen sizesgovuk-!-static-padding-right-5
will apply 25px of padding to the right side of the element at all screen sizesgovuk-!-static-margin-0
will remove all margins at all screen sizesThis was added in pull request #2672: Add static spacing override classes. Thanks to @patrickpatrickpatrick for this contribution.
govuk-header__navigation--no-service-name
class in the headerWe've deprecated the govuk-header__navigation--no-service-name
class, and will remove it in a future major release.
This was added in pull request #2694: Deprecate .govuk-header__navigation--no-service-name.
We've recently made some non-breaking changes to GOV.UK Frontend. Implementing these changes will make your service work better.
hidden
to the mobile menu button in the header componentIf you're not using the Nunjucks macros, add the hidden
attribute to the mobile menu button in the header component. The mobile menu button is govuk-header__menu-button
.
We've changed the header's mobile menu functionality to use the hidden
attribute instead of using CSS to show/hide the mobile menu. Adding hidden
to the mobile menu button by default will make sure that it does not display for users when javascript does not load.
This was added in pull request 2727: Make use of hidden in header navigation functionality. Thanks to @NickColley and @kr8n3r for their contributions.
In pull request 2678: Replace ex units with ems for input lengths, we changed how we define input lengths in our CSS. Browsers might now display these inputs as being slightly wider than before. The difference is usually fewer than 3 pixels.
We’ve also made fixes in the following pull requests:
Changelog
4.2.0 (Feature release)
You can now use pagination to help users navigate forwards and backwards through a series of pages. For example, in search results or guidance that's divided into multiple website pages.
This was added in pull request #2610: Add pagination component.
values
Nunjucks optionWhen using the govukCheckboxes
Nunjucks macro, you can now use the values
option to determine which checkboxes should already be checked when the page loads.
For example, values: ['red', 'blue']
would check any checkboxes that have a value
of 'red' or 'blue'.
You can use this option instead of setting the boolean checked
option on each individual checkbox.
This change was introduced in pull request #2616: Allow selecting options by passing current values.
value
Nunjucks optionWhen using the govukRadios
Nunjucks macro, you can now use the value
option to determine which radio should already be checked when the page loads.
For example, value: 'red'
would check the radio that has a value
of 'red'.
You can use this option instead of setting the boolean checked
option on each individual radio.
This change was introduced in pull request #2616: Allow selecting options by passing current values.

would select the option that has a value
of 'red'.
You can use this option instead of setting the boolean selected
option on each individual option.
This change was introduced in pull request #2616: Allow selecting options by passing current values.
govuk-header__link--service-name
class in the headerIf you're not using the Nunjucks macros in the header, replace any instances of the class govuk-header__link--service-name
with govuk-header__service-name
.
We've deprecated the govuk-header__link--service-name
class, and will remove it in a future major release.
This change was introduced in pull request #2617: Do not make the service name in the header a link if no serviceUrl
is provided.
We have updated our component ES module JavaScript to include missing file extensions not provided in release 4.1.0. If you have received an error similar to the following, for example when running or building your application, this fix should resolve the issue.
Cannot find module '../node_modules/govuk-frontend/govuk-esm/common' imported from ../node_modules/govuk-frontend/govuk-esm/all.mjs
You should not need to make any changes if you are successfully importing our JavaScript as ES modules with version 4.1.0, but there still might be config you can remove. For example, removing fullySpecified: false
from your Webpack config file.
This change was introduced in pull request #2658: Add missing mandatory file extensions for ESM JavaScript. Thanks to @colinrotherham and @tvararu for reporting issues and suggesting and testing fixes.
