BootStrap前端框架学习

Bootstrap 学习

  • 给div标签class只要是col开头的都加上这个样式
<style type="text/css">
    div[class|=col]{
        border: 1px solid;
    }
</style>
  • 响应式工具
visible-xs 到768显示 hidden-xs 到768隐藏
visible-sm          hidden-sm
visible-md          hidden-md
visible-lg          hidden-lg
  • bootstrap栅格系统
流体容器  container-fluid
	width:auto
	两侧15px  padding
固定容器  container-fluid
	阈值
		xs(小于768px)        width:auto
		sm(大于等于768px)     width:720+槽宽
		md(大于等于992px)     width:940+槽宽
		lg(大于等于1200px)    width:1140+槽宽
	两侧15px padding
行
	class='row'
  • bootstrap中轮播图

    在javascript插件中找到carousel即可

  • 对全局的标签进行样式设计

    img{

    ​ width: 100% ;

    }

  • 一般我们在自定义bootstrap样式的时候,最好不要动他的样式,自己加一个样式去修改style

  • .damu-thumbnail img{

    } 让class是damu-thumbnail底下的所有img标签设置演示

  • Html 版权的实体字符https://www.w3school.com.cn/html/html_entities.asp

  • $(document).scrollTop($("#damu-tab").offset().top);

    有让点击某个按钮页面往下偏移到变化的地方的效果

  • $("#damu-nav > li > a")

    • 意思是在id是damu-nav的儿子元素是li的儿子的元素是<a>的元素起作用,也就是damu-nav的孙子元素是<a>的元素起作用

使用bootstrap开发其实我觉得就是面向bootstrap官网开发,所有我们用到的东西都去官网去查找相对应的组件、插件、样式即可!不要傻乎乎的自己去写,效率太低!!!
