Firebug折腾记_(2)HTML&CSS定位及调试小技巧_html/css_WEB-ITnose

Jun 24, 2016 am 11:38 AM

题外话

传统的开发我们是在编辑器操作代码保存,再到浏览器预览查看效果的;
而如今的firebug和chrome的内置调试器就不需要了..可以直接实时编辑且看到效果;
在调试中对代码的操作不会保存到本地实际代码中..是不是很赞!!;

定位HTML元素的三种方式
  1. 进入调试工具界面,按下”瓢虫”旁边的小鼠标,再进行网页元素的选择
  2. 默认快捷键,Ctrl + shift + C
  3. 鼠标移动到网页的某一块元素,鼠标右键,使用Firebug查看元素

HTML及CSS简单调试

##HTML元素编辑
除了写死的代码结构不能操作外(比如DIV块标签),内部的各种属性和内容都支持实时修改和预览的;
修改其中内容,只要单击你选中的东东即可,会有一个小小的蓝色框框出来
比如:

  • 类(class)
  • 行内样式(style)
  • 目标(target)
  • 链接(href)
  • 文本内容
  • 增加额外属性,在包含块的第一个标签的括号内单击即可添加自己想要增加的
  • HTML DOM选定

    可以轻而易举的选定各种包裹层和父类,单击即可

    CSS元素编辑(实时预览)

  • 支持禁用某个属性,点击属性旁边的红色圈圈,被禁用属性会变成灰色
  • 修改某个属性
  • 增加某个属性
  • CSS像素微调技巧

    CSDN不支持GIF动态图..所以没做…..百看不如一试

  • 方向键↑或者方向键↓,上增加1px(em==),下减去1px(em==)
  • Ctrl+↑ 或者Ctrl+↓,上增加0.1px(em==),下减去0.1px(em==)
  • shift+↑ 或者shift+↓,上增加10px(em==),下减去10px(em==)
  • 概览区域

  • 计算出样式可以 ? 可以计算我们选定块的整体大小,很实用
  • 布局 ? 盒模型查看,用来调试布局妥妥的
  • 快捷键及自定义

    全局自定义快捷键调用: ctrl+shift+alt+b,当然也可以点击”瓢虫进去”

    Firebug全局快捷键,支持自定义

    哪个和你的习惯冲突了.修改内部快捷键保存确定即可生效
