CSS(一)

开始学习css之旅：先照样式做一个

一、使用DIV设置

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>第一个css样式</title><link type="text/css" rel="stylesheet" href="css/test1.css"  /></head><body><div></div><div></div><div></div><div></div></body></html>

css:

@charset "utf-8";/* CSS Document *//*定义DIV元素方形显示*/div {    width:200px;    height:200px;    border:solid 2px blue;    float:left;    margin:4px;}

二、使用类设置

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>第一个css样式</title><link type="text/css" rel="stylesheet" href="css/test1.css"  /></head><body><div></div><div></div><div class="green"></div><div class="red"></div></body></html>

css

@charset "utf-8";/* CSS Document *//*定义DIV元素方形显示*/div {    width:200px;    height:200px;    border:solid 2px blue;    float:left;    margin:4px;}/*定义.green类设置背景为绿色*/.green{    background-color:green;}/*定义.red类设置背景为红色*/.red{    background-color:red;}

效果:
