Useful CSS Snippets For Your Core Stylesheet

Hopefully, you are using CSS to stylise and layout your site. If you are not, you should move away from inline styles and start using CSS. The benefits are well worth the time to learn CSS.

Furthermore, if you are not using a CSS pre-processor, you should skill-up and learn one. There are many like SASS, LESS and Stylus. My personal preference is SASS, but my current job requires LESS so I am living in a world between both. They are both quite similar, but I expect SASS is gaining market share. Just look at the latest version of Bootstrap. They have moved their LESS core to SASS. I think that says a lot.

Here are some useful “template” CSS snippets for you to add to your core CSS file. When I say core, I mean a default CSS file that you can port between projects. This file simply does layout, global styles and mixins.

Feel free to add your own examples in the comments.
