CSS3 Patterns, Explained Many of you have probably seen my CSS3 patterns gallery. It became very popular throughout the year and it showed many web developers how powerful CSS3 gradients really are. But how many really understand how these patterns are created? The biggest benefit of CSS-generated backgrounds is that they can be modified directly within the style sheet. This benefit is void if we are just copying and pasting CSS code we don’t understand. Important note In all the examples that follow, I’ll be using gradients without a vendor prefix, for readability and brevity. The syntax described here is the one that browsers currently implement. If you are not yet familiar with CSS gradients, you can read these excellent tutorials by John Allsopp and return here later, as in the rest of the article I assume you already know the CSS gradient basics: The main idea I’m sure most of you can imagine the background this code generates: background: linear-gradient(left, white 20%, #8b0 80%); See this example live

Using CSS gradients lets you display smooth transitions between two or more specified colors. This lets you avoid using images for these effects, thereby reducing download time and bandwidth usage. In addition, because the gradient is generated by the browser, objects with gradients look better when zoomed, and you can adjust your layout much more flexibly. Browsers support two types of gradients: linear, defined with the linear-gradient() function, and radial, defined with radial-gradient(). Linear gradients To create a linear gradient, you set a starting point and a direction (specified as an angle) along which the gradient effect is applied. Simple linear gradients Here's a linear gradient that starts at the center (horizontally) and top (vertically), and starts blue, transitioning to white. background: -prefix-linear-gradient(top, blue, white); background: linear-gradient(to bottom, blue, white); Using angles Size
