The common practice to create gradient background is use images. You can set url with your gradient to background property in css file and nothing more.
But you can also create vertical and horizontal background gradient using css without images
This technic works in the most browsers and it’s easy to use and understand.
Browsers supporting css gradient background
- Firefox >=3.6
- MSIE >=5.5 (!)
- Safari >=4
- Chrome
Gradient background without image for Firefox
Firefox support css property -moz-linear-gradient, using this property you can create both vertical and horizontal gradient only using CSS, without images. You can use it this way
background: -moz-linear-gradient(top, #880000, #000000);
The first parameter shows the direction of gradient, top means than gradient will be from bottom to top. The first color is start color, and the second color is finish gradient color.
Gradient background CSS without images in Chrome and Safari
Chrome and Safari support -webkit-gradient css property. The usage is below:
background: -webkit-gradient(linear,
left top, left bottom, from(#880000), to(#000000));
First parameter is type of gradient, it can be either linear or radial. The second two parameters show direction of gradient, for example here gradient starts at left top corner of the element and finishes at left bottom corner of element.
And the last two parameters show start and end colors.
Notes:
- A gradient applied to a rectangle area is called a linear gradient.
- A gradient specified using circles is called a radial gradient.
