The .gov means it’s official.
Federal government websites often end in .gov or .mil. Before sharing sensitive information, make sure you’re on a federal government site.


The site is secure.
The https:// ensures that you are connecting to the official website and that any information you provide is encrypted and transmitted securely.


Sass Comments

Be intentional when you use // (silent comments) versus /* */ (which are preserved in the CSS output). When in doubt, use //.


Use KSS for documentation. More information on KSS can be found on the official site.


// Button
// Various buttons on the site.
// Markup
// <a class="button ">

// .button-modified - A button with a different style.

.button {

.button-modified {


KSS is the most common CSS documentation method to date. While it’s not perfect, the generated documentation can be modified through templates.
