When signifying angles for directions, you need to do some recalculation, as 0deg used to mean horizontal towards the right (equivalent to left), and now it means vertical and upwards (equivalent to to top).

So top left is equivalent to to bottom right, bottom is equivalent to to top, and so on.

The direction keywords are the opposite way round and don’t include the word to.

For compatibility with older browser versions and WebKit versions, you should consider including vendor prefixes versions of the property, all including the older syntax. Note that the newest versions of Opera, Firefox and IE all support the current syntax of linear gradients, without prefixes, while WebKit-based browsers still require the old syntax. Figure 6: A repeating gradient example Browser support, and old syntax The above example looks something like Figure 6.

This is the default, and is equivalent to writing this:īackground-image:repeating-linear-gradient( In the first example, we didn’t specify any kind of direction or angle, and the gradient went from the top of the block to the bottom.

In modern browsers, the gradient will hide the color.

To prevent older browsers displaying white text on the white background of the page, you can give your button a background-color:gray so the text remains readable and the button doesn’t appear broken.

So why is the gradient applied as a background image and not a background colour, which might seem more appropriate? This is because of flexibility and familiarity. Figure 1: A really basic CSS3 linear gradient Here I’m applying it to a simple article element, but you can apply it to any block level element you like. This creates a simple gradient that goes from a darker grey at the top of the element the gradient is applied to, down to a lighter grey at the bottom, as seen in Figure 1.
