2 Naming Convention
Naming Convention Naming convention clari es intent
Use Class over ID Don’t use a grenade to dig
a hole when a shovel will do.
.btn {} .btn-large {} .btn-small {} .btn-default {} .btn-search {}
.btn {} .is-btn-active {} .is-btn-disabled {}
.theme-header {} .theme-border {} .theme-background {}
.text-plus1 {} .text-minus1 {}
3 Decoupling CSS from HTML
.nav { margin: 0; padding: 0; list-style: none; } .nav
li { float: left; } .nav li a { display: block; padding: 5px 10px; background-color: blue; }
<ul class="nav"> <li><a href="/">Home</a></li> <li><a href="/products">Products</a></li> <li><a href="/contact">Contact Us</a></li> </ul>
<ul class="nav"> <li><a href="/">Home</a></li> <li><a href="/products">Products</a> <ul> <li><a href="/products/shoes">Shoes</a></li> <li><a
href="/products/jackets">Jackets</a></li> </ul> </li> <li><a href="/contact">Contact Us</a></li> </ul>
.nav ul { margin: 0; padding:0; list-style:none; } .nav li
li { float: none; } .nav li li a { padding: 2px; background-color: red; }
.nav { margin: 0; padding: 0; list-style: none; } .nav
> li { float: left; } .nav > li > a { display: block; padding: 5px 10px; background-color: blue; }
.menu { margin: 0; padding: 0; list-style: none } .menu
> li > a { display: block; padding: 2px; background-color: red; }
Please. Use child selectors
<div class="box"> <h2>Sites I Like</h2> <ul> <li><a href="http://smashingconf.com/">Smashing!</a></li> <li><a href="http://smacss.com/">SMACSS</a></li>
</ul> </div>
.box { border: 1px solid #333; } .box h2 {

when the HTML can’t or won’t be predictable Apply a
class
What does it mean?
Shift your thinking
Don’t code CSS for the page. Code it for the
system.
Have your CSS... Do one thing and one thing only
State-based Design
State-based Design • A layout or module style • Sub-modules
• JavaScript-driven states • Pseudo-class states • Media query states
