The simplicity of CSS lies in its ease of learning, but the difficulty of CSS lies in finding better solutions. In the world of CSS, there seems to be no such thing as perfection. Therefore, the CSS introduced now is the absolute bottom, and it is just the most perfect solution among the solutions I have seen so far.

First let’s talk about why we use this CSS bottom layout solution:

When making a page, if the page content is very small and not enough to fill the window area of ​​a screen, follow the normal layout , it will look like the picture below (that is, the bottom content is not located at the bottom of the window, leaving a lot of blank space.

For designers who pursue imperfection, This is not beautiful. There are some solutions on the Internet, but when changing the window height, there will be a bug that the bottom and the text overlap. Although not many people will change the window height without any trouble, the design is to pursue perfection. .

The following is a relatively perfect method I found, which can be achieved by a foreign design expert using pure CSS: When the text content is small, the bottom is at the bottom of the window. There will be no overlapping problem.

Even the person who created this CSS has set up a website to introduce this CSS bottom layout scheme. I don’t know if he has applied for a patent:)

HTML code:

Note: The prerequisite for using this layout is that the footer must be in the overall div container In addition, the footer uses a layer and everything else uses an overall layer. If you really need to add other sibling layers, then this sibling layer must use position:absolute for absolute positioning.

In the world of CSS, there seems to be no such thing as perfection. Therefore, the CSS introduced now is the absolute bottom, and it is just the most perfect solution among the solutions I have seen so far.

CSS code:

The following is the main CSS code so that your bottom can be at the bottom of the window:

html, body, # wrap {height: 100%;}
body > #wrap {height: auto; min-height: 100%;}
#main {padding-bottom: 150px;} /* Must use footer Same height*/
#footer {position: relative;
margin-top: -150px; /* Negative value of footer height*/
height: 150px;
clear: both;}

Note: What needs to be noted is that the padding value of #main, the height of footer and the negative margin value need to be consistent.

It’s that simple, but it’s not over yet. If your main body uses a floating layout, you have to solve some browser compatibility issues. The focus here is on Google Chrome.

Perform the famous Clearfix Hack on the #main part:

.clearfix:after {content: ".";
display: block;
height: 0;
clear: both;
visibility: hidden;}
.clearfix {display: inline-block;}
/* Hides from IE-mac */
* html .clearfix { height: 1%;}
.clearfix {display: block;}
/* End hide from IE-mac */Note: This solution was tested on a two-column floating layout and is compatible with all major mainstream Browsers, including Google Chrome.

P.S:The previously well-known footer layout on the Internet was created by Ryan Faits, but its method will have an empty div layer in the HTML code. Strictly speaking, it does not comply with the Semantic Web code standards. Also, there is an Exploring Footers article from A List Apart , but it uses some JavaScript code. In this comparison, the seemingly simple pure CSS above appears much greater.
