Cross-browser alternative to -webkit-text-security
. Check out demo at noppa.github.io/text-security.html.
text-security is a simple set of fonts that only consist of 3 different characters.
Disc (the shape normally used in password fields), circle and square. For example, setting
font-family: "text-security-circle"
for
an element should then display all the element's characters in a concealed
way, like it was a password field. This is useful if you want to get the benefits of input[type="password"]
but also combine that with other element types, like input[type="tel"]
. In
fact, the project was created for this exact purpose as an answer to a
StackOverflow
question.
Tested in recent versions of Chrome (for desktop and mobile), Edge,
Firefox, Safari for iOS and IE 11. Opera Mini is not supported, as it
does not support @font-face
web fonts.
Modern browsers that support WOFF2 and
cmap subtable format 12 will use the optimized WOFF2 font, which is only 0.8 kb in size.
Older browsers like IE will automatically load the compatibility TTF and EOT fonts
whose names are suffixed "-compat" and weigh about 200 kb.
The project builds on top of Adobe's similar font projects Adobe Notdef
and Adobe Blank 2.
Installation
npm install text-security
You can use the fonts by adding this project as a dependency and including
text-security.css
in your project.
<link href="node_modules/text-security/text-security.css" rel="stylesheet" type="text/css">
Alternatively, you can grab the fonts you need (most likely text-security-disc and text-security-disc-compat)
from the releases page and include your own @font-face
definition in CSS.
src/style-template.css should give a pretty good idea how to do that, just
change the font name and source path to match your setup.
CSS Example
After the font is loaded, making a field behave like password field is easy.
.my-password-field {
font-family: text-security-disc;
-webkit-text-security: disc;
}
Building with custom modifications
This repository contains the build scripts needed for creating these fonts.
If you want to add your own shapes or do other modifications, see Development.md.
Lisence
The published font is lisenced with SIL Open Font Lisence.
This is the only lisence you need to care about if you are simply using the prebuilt fonts.
All the code in this repository that is used for generating these fonts (Dockerfile, Python & shell scripts etc.)
are lisenced MIT.
This project builds on top of Adobe's font projects Adobe Notdef
and Adobe Blank 2, which are included as submodules.
They are also lisenced with SIL.
Also included as submodules are
ttf2eot and
t1utils. t1utils has a slightly modified MIT lisence here. ttf2eot is extracted from Chromium project.
