Advanced tools
Use pow(), sqrt(), hypot(), log(), exp() exponential functions in CSS
@csstools/postcss-exponential-functions is a PostCSS plugin that allows you to use exponential functions in your CSS. This can be particularly useful for creating smooth transitions and animations, as well as for responsive design calculations.
Exponential Functions in CSS
This feature allows you to use exponential functions directly in your CSS. The `exp(base, exponent)` function calculates the base raised to the power of the exponent.
/* Input CSS */
.element {
width: exp(2, 3)px; /* 2^3 = 8px */
height: exp(3, 2)px; /* 3^2 = 9px */
}
/* Output CSS */
.element {
width: 8px;
height: 9px;
}
Logarithmic Functions in CSS
This feature allows you to use logarithmic functions in your CSS. The `log(value, base)` function calculates the logarithm of the value with the specified base.
/* Input CSS */
.element {
width: log(8, 2)px; /* log base 2 of 8 = 3px */
height: log(9, 3)px; /* log base 3 of 9 = 2px */
}
/* Output CSS */
.element {
width: 3px;
height: 2px;
}
postcss-calc is a PostCSS plugin that reduces calc() references whenever it's possible. It allows you to perform mathematical operations within your CSS, similar to @csstools/postcss-exponential-functions, but it focuses on basic arithmetic operations rather than exponential and logarithmic functions.
postcss-math is a PostCSS plugin that allows you to use mathematical expressions in your CSS. It supports a wide range of mathematical functions, including trigonometric and logarithmic functions, making it a more comprehensive alternative to @csstools/postcss-exponential-functions.
npm install @csstools/postcss-exponential-functions --save-dev
PostCSS Exponential Functions lets you use the pow()
, sqrt()
, hypot()
, log()
, exp()
functions following the CSS Values 4 Specification.
.foo {
top: calc(1px * pow(2, 3));
line-height: sqrt(1.2);
padding: hypot(3px, 4px);
order: log(10, 10);
min-height: calc(e - exp(1));
}
/* becomes */
.foo {
top: 8px;
line-height: 1.0954451150103;
padding: 5px;
order: 1;
min-height: 0;
}
Add PostCSS Exponential Functions to your project:
npm install postcss @csstools/postcss-exponential-functions --save-dev
Use it as a PostCSS plugin:
const postcss = require('postcss');
const postcssExponentialFunctions = require('@csstools/postcss-exponential-functions');
postcss([
postcssExponentialFunctions(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);
PostCSS Exponential Functions runs in all Node environments, with special instructions for:
The preserve
option determines whether the original notation
is preserved. By default, it is not preserved.
postcssExponentialFunctions({ preserve: true })
.foo {
top: calc(1px * pow(2, 3));
line-height: sqrt(1.2);
padding: hypot(3px, 4px);
order: log(10, 10);
min-height: calc(e - exp(1));
}
/* becomes */
.foo {
top: 8px;
top: calc(1px * pow(2, 3));
line-height: 1.0954451150103;
line-height: sqrt(1.2);
padding: 5px;
padding: hypot(3px, 4px);
order: 1;
order: log(10, 10);
min-height: 0;
min-height: calc(e - exp(1));
}
