How to fix table header with pure CSS? Implementation of table header fixation-CSS Tutorial-php.cn

The content of this article is to introduce how to achieve table header fixation with pure CSS? Implementation of header fixation. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

The reason why it is difficult to achieve table header fixation with pure CSS is mainly due to two points:

1. IE6, which has the largest market share, does not support position:fixed.

2. People want to achieve this effect in a table.

However, foreign people have actually achieved this effect using pure CSS, using an amazing number of CSS hacks... I think if the code is so difficult to understand and difficult to expand, it is better to use javascript. It happened that I also encountered this kind of need today. Thinking about it from a different perspective, I really figured it out.

We know that CSS is responsible for performance, and HTML is responsible for structure. The same structure, but changing the style, will give people a completely different feeling. This also shows that human eyes are easily deceived. Therefore, in the days when p CSS was enthusiastically advocated, people always wanted to remove tables from the page and used p span to create "tables" one by one.

Although this kind of thing is not advisable, it also tells us that what table can do, we can also do it through some combinations. To put it another way, since one table cannot be done, just two.

The upper table simulates the header, and the lower table simulates the part with scroll bars. Before we go any further, let's clarify our needs first, without being too abstract. First, the table is 4*9, each column is 170px wide, and the total is 680px. The scroll bar defaults to 16px in each browser. Don’t forget, the width does not include the border. There are 5 vertical borders in four columns. The width Total length is 701px.

Then we divide this table into two. The first table is the header, and the second table should have a scroll bar, which means that the overflow style should be applied to its parent element, so it needs to be coated with a p. This p and the first table should be of equal length.

But don’t worry, we put a p outside them, set their width to 701px, and then set the width of these two sub-elements to 100%. Note that we explicitly add tbody to the table to improve the rendering efficiency of the table.

Discover the grid and table of the header The body grid is not aligned. At this time we need to use the col tag. col allows us to uniformly set the background color, text alignment and width of td or th with the same index value in tbody. Although the adjacent selector of CSS2.1 and the sub-element filtering pseudo-class of CSS3 allow us to set them in a more streamlined way, and the style and structure are separated, it is a pity that the IE family always lags behind. Let's take a look at their lengths again. Since the last table may be squeezed by the scroll bar and shortened in length, we just need to ensure that the lengths of the first three columns are equal, and the rest are allocated to the last one. In other words, the last one does not need to be set. In addition, you can set the style of the scroll bar in IE, let's play around with it.
