This time I will bring you the paging ideas of the website and the paging effect when making the website. What are the precautions? . The following is a practical case. Let’s take a look.

When making a website, many paging uses li to display inline, but this is not conducive to defining the background, so the best way is to let li display as a block and add float to solve the problem, but here is a The problem is, because the paging is not fixed, and it must always be centered, the width of ul cannot be fixed, so the commonly used margin or text-align will not work. I want to Pagination is always centered and must be defined as follows.
1. Text centering definition
Text centering is always necessary, so first give the ul outer div a text-align (text alignment: centered), and you can also give an "overflow: hidden; )", of course you can also define the height and width.
2.ul definition
ul cannot define the width, we can only give one positioning, the type is relative (position: relative), the left position is 50% (left: 50%), Of course a float can also be given. Please note that ul must not be hidden with overflow: hidden;, so that part of the li cannot be displayed.
3.li definition
The definition of li is similar to that of ul. The width is not fixed. It also gives a positioning. The type is relative (position: relative). The placement right is 50% (right: 50%), which is exactly the same as On the contrary, ul is defined in this way so that li can always be centered regardless of the number of pages.
