Today, the editor will share with you the relevant knowledge points about how to use relative positioning in css. 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.

one。 Basic concepts:

As the name implies, this positioning is an offset from an object, and relative positioning does not detach the object from the document stream, and although its position may be offset, the initial position of the object is retained.

If you really want to master this method of positioning, figuring out which object you want to offset from is the key point.

two。 How to set an element to relative positioning:

Relative positioning occurs when the position property value of an object is set to relative:

The code is as follows:

Position:relative

three。 Locate the reference object:

You can use the top property and the left property to set the offset from the anchored object.

The offset reference object for relative positioning is the object itself.

Code example:

First, take a look at a code example that does not use location:

The code is as follows:

CSS relative location-ant tribe

.father {

Width:400px

Height:400px

Background-color:green

Margin:50px

}

.first {

Width:100px

Height:100px

Background-color:red

}

.second {

Width:100px

Height:100px

Background-color:blue

}

In the above code, all the objects do not use relative positioning, so there is no need to introduce them here.

Let's look at a piece of code that uses relative positioning:

The code is as follows:

CSS relative positioning

.father {

Width:400px

Height:400px

Background-color:green

Margin:50px

}

.first {

Width:100px

Height:100px

Background-color:red

Position:relative

Left:20px

Top:30px

}

.second {

Width:100px

Height:100px

Background-color:blue

}
