    copied!<p>I will try to explain my question with a little bit of CSS</p> <h2>Option 1</h2> <p>I don't repeat the <code>float:left;</code> all over the place, instead I chain all the class names that are going to float left together.</p> <pre> .one-little-thing, .two-little-things, .three-little-things, .four-little-things, .five-little-things { float:left; } .one-little-thing { color: blue; } .two-little-things { color: red; } .three-little-things { color: yellow; } .four-little-things { color: blue; } .five-little-things { color: green; } </pre> <p>Total Number of Characters: 331 (including spaces, but even if you trim the spaces, the example is going to be valid)</p> <h2>Option 2</h2> <ul> <li>Where I repeat float:left; all over the place, but I get slightly less characters.</li> </ul> <pre> .one-little-thing { color: blue; float:left; } .two-little-things { color: red; float:left; } .three-little-things { color: yellow; float:left; } .four-little-things { color: blue; float:left; } .five-little-things { color: green; float:left; } </pre> <p>Total Number of Characters: 284</p> <p>I did exactly the same thing with both pieces of code here, the second way has less characters, which means less bytes. </p> <p><strong>So my question is this:</strong><br> Does this mean that the second way is better for performance ? What if I had up to ninety-nine-little-things ?</p> <p><strong>Why it concerns me</strong><br> The <code>@extend</code> in Sass allows to for example to <code>@extend .clearfix;</code>, which, if used as in "Option 1" would result in a very, very long selector.</p> <p>So which is the best way ?</p>
