固定一列的宽度或者高度:
建议:尽可能的手写代码，可以有效的提高学习效率和深度。
在实际使用中往往需要给一个块设定固定的宽度或者高度，这一使用比较简单基础。
首先我们在文档中建立一个class名称为mytest的div，然后通过内联样式表设置div的宽度和高度。为了便于查看效果，div的background-color值设置为green。下面给出完整代码:
<!DOCTYPE html><html><head><meta charset="utf-8"><meta name="author" content="http://www.softwhy.com/" /><title>蚂蚁部落</title><style type="text/css">.mytest { background-color:green; width:200px; height:200px;}</style></head><body><div class="mytest"> </div></body></html> 以上代码将div的高度和宽度分别固定为200px。
