Type is all set with the rems, so font-sizes and spacial relationships can be responsively sized based on a single <html> font-size property. Out of the box, Skeleton never changes the <html> font-size, but it's there in case you need it for your project. All measurements are still base 10 though so, an <h1> with 5.0remfont-size just means 50px.
<h1> 50rem<h2> 42rem<h3> 36rem<h4> 30rem<h5> 24rem<h6> 15remButtons come in two basic flavors in Skeleton. The standard <button> element is plain, whereas the .button-primary button is vibrant and prominent. Button styles are applied to a number of appropriate form elements, but can also be arbitrarily attached to anchors with a .button class.
Code styling is kept basic – just wrap anything in a <code> and it will appear like this. For blocks of code, wrap a <code> with a <pre>.
.some-class {
background-color: red;
}
