Relative positioning and absolute positioning in html

Let’s talk about relative positioning and absolute positioning in html. Some back-end students are not familiar with the relative positioning and absolute positioning of html. Here comes the bonus, this article talks about the relative positioning and absolute positioning of html in detail!

html is the entire document space, body is the document space in html, the difference between body and html is about 9cm

Relative positioning in postion: relative

Absolute positioning in postion: absolute

Relative positioning:

When there is no reference object , relative positioning is relative to body positioning

Absolute positioning:

When there is no reference object, absolute positioning is relative to html positioning

When using margin, it takes up document space. It is generally used in relative positioning.

When using top, left, right, button, it does not occupy document space. , use it depending on the situation

We usually use absolute within relative to develop the project

               #divAddress{
                    position: relative;
                    margin-top: 48px;//这就是刚才提的当使用margin的时候才能进行下面的相对
                    width: 370px;
                    height: 66px;
                    border-bottom: 1px #c1c1c1 solid;
                }
                #img1{
                    position: absolute;
                    float: left;margin-top:2px;
                    width: 24px; height: 24px;
