7. Implementation of CSS3 multi-background (Multiple backgrounds)

You should be familiar with the background attribute background-image. In CSS2, the attributes related to this attribute are also background-repeat (set whether the background is repeated or not) background-position (set the position of the background image in the container) and background-attachment (set whether the background is scrolled along with the page). These attributes are used to control how the background image is displayed in the container, however, we can only provide one background image for the container. If we want to use multiple images for the background of a container, what should we do? Then add some useless elements to the container?

The birth of CSS3 solves this problem. In CSS3, multiple background images can be set for a container through background-image or background, that is to say, we can put different background images in only one block element.

First, let's look at the Syntax:

Background: [background-image] | [background-origin] | [background-clip] | [background-repeat] | [background-size] | [background-attachment] | [background-position]

Separate URLs of multiple background images with commas (,). If there are multiple background images and only one other attribute (for example, background-repeat) exists ), this attribute value is applied to all background images.

It is better to learn which website jquery and other web Front-ends are on.

Jquery's official website is fine. Learning jquery is mainly used for multiple purposes. First, write it according to the basic example. The best way is to directly look at jquery's source code. After getting familiar with jquery, you can check it out. It is very enlightening.

After two years of web Front-end development, I am engaged in developing web apps for HTML5 and jQuery Mobile apps. It will soon end in my junior year and start school next semester.

I tell you: it may take some money to find a company that is both engaged in app R & D and app training, but you need to be diligent and concentrate on copying the master's experience for a few months, you are experienced.
