bivald / photoshop-to-css.sass
Created March 7, 2014 09:02
Sass mixin to convert photoshop line-height to CSS, photoshop letter-spacing to CSS
/* Reset rem to 10-based instead of default browser 16 */
html {
font-size: 62.5%;
}
/*
Photoshop does not apply line height to the first row, which CSS does. This creates all kinds of havock.
To calculate the correct offset for the first line we need the font-size and the lineheight, i.e:
@include line-height(22,30);
