sass Convert units Convert px to (r)em
Example
To convert px to em or rem you can use the following function:
@function rem-calc($size, $font-size : $font-size) {
$font-size: $font-size + 0px;
$remSize: $size / $font-size;
@return #{$remSize}rem;
}
@function em-calc($size, $font-size : $font-size) {
$font-size: $font-size + 0px;
$remSize: $size / $font-size;
@return #{$remSize}em;
}
The $font-size is the original font size.
For example:
$font-size: 14;
body {
font-size: #{$font-size}px;
font-size: rem-calc(14px); // returns 1rem
// font-size: rem-calc(28); // returns 2rem
}
