一列固定、一列宽度自适应:
建议:尽可能的手写代码，可以有效的提高学习效率和深度。
之前的代码中，已经介绍过一列宽度自适应和二列宽度自适应，实现自适应的效果一般就是将相应对象的宽度以百分比的形式表示。在实际的布局中，一列宽度固定、一列宽度自适应。下面我们就以左侧div宽度固定，右侧div宽度是自适应为例。
代码实例:
<!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">body{ margin:0px; padding:0px;}.left{ width:200px; height:50px; background-color:green; position:absolute; left:0px;}.right{ height:50px; background-color:blue; margin-left:200px;}</style></head><body><div class="left">我是左边</div><div class="right">我是右边</div></body></html>以上代码中左栏div宽度是固定值200px，并且将其进行绝对定位，这样它就脱离文档流了，不会对周围的div定位造成影响。这个时候设置右边div的左外边距等于左边div的宽度，且不设置此div的宽度以达到宽度自使用效果。
