Today, the editor will share with you the background of css and the relevant knowledge points about how to set background. The content is detailed and the logic is clear. I believe most people still know too much about this, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

Grammar and structure

1. Grammar:

Background: bac kg round-color | | bac kg round-image | | bac kg round-repeat | | background-attachment | | background-position

2. The parameters of bac kilogram round are indicated:

The bac kilogram round attribute is a composite attribute. It is popular to say that the post-round value of bac kg can be set to multiple values, such as setting colors, repeated tiling of set pictures, and other specific backing details.

Second, bac kilogram round attribute split

1. The hue of the diameter self-setting

Background-color:#000

Configure the backup hue to black.

But the abbreviation of the introduction:

Background:#000

Get rid of-color in background-color, and the result is no less than a waste of code.

2. Background picture

Background-image:url (where the scenery picture is located); bac kg round-repeat:no-repeat;bac kg round-position:10px 20px

Set up the equipment backer picture (introduce the picture as the backer), the picture does not background-repeat:no-repeat; again and again (background-repeat:no-repeat;), after the picture as the backing, the picture is the primary representation of the 10px on the right side of the object, and the picture is away from the above 20px to reveal the performance (bac kg round-position:10px 20px).

Introduction abbreviation:

Bac kg round:url (backer picture) no-repeat 10px 20px

Scene CSS values can be separated by spaces, throwing away the code and communicating results at the same time, compare the odd attribute setting equipment and the acronym bac kilogram round to see if you can waste CSS code.

III. Bac kg round profile

The background color of the above CSS setting is # CCC, and the image logo.gif is introduced (the path must be accurate or you have no choice but to introduce the backing image). The object in the background image does not flash again and again, and the image begins to be separated by the left 10px and the upper interval 20px.

4. Configure background color

Backup hue or novice will want to use bac kg round-color to configure, but it is recommended that the abbreviation of the austerity code can be directly used with the backkilogram round attribute.

The following example sets the CSS width and CSS height pattern in order to peek into the various names of the scenery fancy in DIV.
