*{ margin:0; padding:0;}body { text-align:center; background:url(bg.jpg);}a:link { color: #A0410D; text-decoration:none; }a:visited { color: #A0410D; text-decoration:none; }a:active { color: #A0410D; cursor:hand; text-decoration:none; }a:hover { color: #FFCC17; cursor:hand; text-decoration:"underline"; }h1,h2,h3,h4{ color:#C36C2D;}#wrap{ width:800px; margin:0 auto; text-align:left;}#header{ height:118px; text-align:center; background:#FDE38F url(logo.jpg) no-repeat;}#header h1{ line-height:118px;}#menu{ height:22px; background:url(bar.jpg) repeat-x;}#container{ float:left; background:#A0410D;}#side{ width:200px; float:left;}#content{ width:600px; float:left; height:400px; background:white;}#footer{ clear:both; height:22px; text-align:right;}#footer p{ line-height:22px;}
[ Description】
1. *{ margin:0; padding:0;} is a loose style reset. To build your own website, you generally need a reset.css. Please refer to reset.css content. http://blog.csdn.net/yousuosi/article/details/7939325
2. Text-aling:center is set in the body, and text-align:left is set in the wrap, which seems a bit redundant. , this is to solve the compatibility problem of old version browsers. For new versions of browsers, a margin:0 auto; in wrap can solve the centering problem.
3. The problem of vertical centering of the title h1 in div#header. You can set the line-height of h1: 118px, that is, the line height of h1 is consistent with the height of div#header.
4. Side and content divs are juxtaposed. They can be positioned absolutely, or they can be floated like this example. When floating, the two divs are set to float:left; Attributes will break away from the standard flow. At this time, in order to ensure that the container can still surround the two divs, it is also set to float.
5. Since the side, content and content are all set to float, the footer that follows needs to set clear:both; to clear the impact of floating. This is a habit.
Sixth, setting the background color of two side-by-side divs. There is a problem, that is, the height of the content usually changes with the content. At this time, it is difficult to ensure that the height of the side is consistent with the content. The solution is to set the background color of the side on the container. The side does not have a background color. Because the content needs to store web content, the background color generally needs to be set lighter, or simply set to white.
7. Fixed-width and centered layouts can also use absolute positioning attributes. For details, please refer to the typical DIV+CSS layout - left, center and right layout.
[Conclusion]
For programmers, they don’t understand the front desk at all, and they can’t even make a simple interface. It will indeed undermine people’s confidence. When doing back-end code, it will also No confidence. And it is unrealistic to ask programmers to make beautiful front-end interfaces. To make interfaces, you need to have profound artistic accomplishments, a foundation in art, and rich image thinking skills. This is different from the logic that programmers are good at. There is conflict in thinking. At this point, programmers must have a good positioning for themselves. Personally, I think that maybe CSS is the interface between the backend code and the frontend interface...
Programmers should understand the Web standard design idea of separation of structure, content and performance, and master the basic HTML structure. Master basic CSS design, and be able to use simple colors and a small number of pictures to build an interface that conforms to Web standards. It can be considered a demo. The HTML structure must be reasonable and the CSS must be standardized. On this basis, artists and front desk staff Only then can they use their imagination to build a truly beautiful interface. At this time, the structure and content of the interface will not be affected.
