11 useful CSS snippets to save your time

Writing CSS can be a pain and can give you headaches. The truth is that CSS ain't rocket science and you should just have in mind some CSS pieces of code (snippets) you can use everytime.

In the following rows I'll try to present you some important snippets I often use in my project and I hope these will help you too.

Useful CSS snippets

1. CSS Reset

CSS reset

The best way to start a CSS file is to choose a CSS reset method from a various list of existing ones.

2. Clear floated elements without any extra markup

Clear floated elements without extra markup


  <li>First floated element</li>
  <li>Second one</li>


ul {
  width: 100%;
  overflow: hidden;

li {
  float: left;

3. Use border-radius instead of -webkit-border-radius

Since Chrome and Safari began to use border-radius property, you no longer have to use -webkit-border-radius anymore. So, for your rounded corners just add:

-moz-border-radius: 10px; /* Mozilla */
border-radius: 10px; /* Chrome, Safari, Opera ... */

4. CSS3 Box-shadow, text-shadow, gradients and transform properties

Define complex box shadow declarations so you can tune up your website:

box-shadow: 0 2px 2px rgba(0, 0, 0, 0.2), 
            0 1px 0 rgba(255, 255, 255, 0.8) inset;

Text shadow as a 1px white stroke effect:

text-shadow: 0 1px 0 white, 0 -1px 0 white;

Nice gradients using CSS:

background-color: #eaeaea; /* Fallback background */
background-image: linear-gradient(#fafafa,#eaeaea);

Use CSS transform for hover effects:

transform: scale(1.1);

5. Image replacement technique

This CSS technique is very common and easy to use, you can keep text for search engines and also style the element as you wish by adding an image instead. Here you have a quick example:

h1 {
  background: url(img/replacement-image.png) no-repeat;
  height: 50px;
  width: 400px;
  display: block;
  text-indent: -9999px;

6. Centering a div of unknown width

div {
  display: table;
  margin: 0 auto;

...and, as IE6 and IE7 don't support the "display: table" declaration you can use an alternative method I often use:

<table class="centered-block">
  <!-- Here you'll write your variable witdh block content -->

Here's the simple CSS for that:

.centered-block {
  margin-left: auto !important;
  margin-right: auto !important;


The main advantages of this method

  • It's valid
  • and it's also a cross-browser solution


A disadvantage would be the fact that includes extra HTML markup and you should consider that before using it.

7. Advanced selectors

You may use these selectors to target easier your elements like text inputs or to style links to pdf files for example:

input[type="text"] {
  padding: 5px;
  border: 1px solid #eaeaea;

a[href$=".pdf"] {
   background: url(pdf-icon.png) no-repeat left center;

8. Min-height

The IE6 browser threats last declaration like min-width.

div {
  min-height: 500px;
  height: auto !important;
  height: 500px;

9. Fix IE6/7 double margin/padding bug

This problem appears when a left/right floated elements has a margin/padding value defined. To fix that just target these browsers as you earlier learned in this article and add "display: inline" declaration.

ul li {
  float: right;
  margin-right: 10px;
  *display: inline; /*Target IE7 and bellow*/
  _display: inline; /*Target IE6 and bellow*/
/* This example fixes the double right margin bug */

Note that you can use these IE6/7 hacks or you can use conditional comments.

10.The font shorthand

As always this is very handy as it merges multiple lines of code.

/*font: font-style font-variant font-weight font-size/line-height font-family;*/
font: italic small-caps bold 12px/20px Arial, Helvetica;

11.Change text selection style

CSS3 text selection

If your get tired of the default blue background selection and white text when you highlight text on a browser then you can try the following.

::selection {
  color: white;
  background-color: red;

/* Firefox needs an extra attention for this */
::-moz-selection  {
  color: white;
  background-color: red;

These are just some example I had in mind at the time I wrote this article but for sure there are a lot of CSS snippets worthy to mention about, let me know which one you use from this list and not only.
