微软的IEDevToolBar，是一个免费的为Web开发人员制作的IE插件

主要功能有：

1.以树结构查看CodeDom，并查看每个Element属性，可以使用鼠标点击选中Element，这个在我们制作Skin时很有用
    2.生成图片报表，就是将页面上说有出现的图片生成一份详细的报表，这样就省的我们自己去找图片路径和量图片大小等等。
    3.高亮显示表格，表格单元，Div等的边框，这个在我们调整布局时也是很有用
    4.页面尺子，可以然你任意在页面上度量长度，这个是大大的提高了我们的工作效率，不用为了量个长度而抓图再用画图工具量

IEDevToolBar使用方法:

安装之后，在IE顶部菜单的“查看” － “工具栏” 里面钩选“Developer Toolbar”项即可。这下在IE下做 Web开发就方便多了！
