常用css属性

1.伸缩导航菜单

a{display:block;height:30px;text-align:center; line-height:30px; width:120px; background-color:#ccc;}
a:hover{ color:#fff;background-color:#F60;height:40px; line-height:40px;  margin-top:-10px;}

2.padding与margin,如果没有设置父元素宽高,俩者之间可以通过背景颜色分辨出是margin还是padding

margin-top: 44px;margin-left:50px;background: red;
padding-top: 44px;padding-left:50px;background: red;

3.制作一条下滑小线(i元素空白)

 .line i{display: inline-block;width: 40px;border-bottom: 1px solid #fff;}

4.制作一条横线(-)

.line i{display: inline-block;width: 40px;border-bottom: 1px solid #fff;vertical-align: middle;}

5.制造一条定位在右侧间隔线高度128px厚度在1px的线

.wrapper li .line{position:absolute;right:0;top:5px;width:0px;height:128px;border-right:1px dashed #cacaca;} 

6.做一个领线

.index-menu .menu-tips{position:absolute;left:50%;top:0;margin-left: -78px;width: 156px;height:75px;border: 1px solid blue;text-align: center;line-height:65px;color:#FFF;background: #f34949;}
.index-menu .menu-tips:after{position: absolute;content: "a";left:0;bottom:0;width:0;height: 0;border-left:78px solid transparent;border-right: 78px solid transparent;border-bottom: 20px solid #fff;}

精简版尖角不能修改

.index-menu .menu-tips:after{position: absolute;content: "";left:0;bottom:0;border-left:78px solid transparent;border-right: 78px solid transparent;border-bottom: 20px solid #ccc;}

 

border-bottom是尖角的距离,边框类型以及边框填充颜色
left:0;bottom:0;是绝对定位元素,最左边并且最底部显示
border-left和border-right的78px是相对于父级元素宽度156px的尖角居中。
.index-menu .menu-tips:after{position: absolute;content: "";left:0;bottom:0;width:46px;border-left:55px solid transparent;border-right: 55px solid transparent;border-bottom: 20px solid grey;}

尖角变平角居中是因为宽度width:46px;等于(156px-46px)/2=55px;

7.制作一个好看的目录标题

style="display: inline-block;min-width:30%;background: #DEECF4; border-radius: 6px; box-shadow: 0 0 0 1px #5F5A4B, 1px 1px 6px 1px rgba(10, 10, 0, 0.5); color: #3b3939; font-size: 15px; line-height: 24px; font-weight:bold;margin: 12px 0 !important; padding: 5px 5px 5px 10px; font-family: '微软雅黑';"

          

7.2制作一个好看的目录标题——2

 

 

style="min-width: 30%; background: #5f5a4b; box-shadow: 0 0 0 1px #5f5a4b, 1px 1px 6px 1px rgba(10,10,0,.5); color: #ffffff; ;padding: 5px 0px 5px 8px; text-shadow: 2px 2px 3px #222222; margin: 15px 0 !important; height: 25px; font-weight: normal !important; font-family: '微软雅黑'; border-radius: 7px; border: 1px solid black;"

7.5.制作一个代码背景

style="margin: 15px 0; font: 100 12px/18px monaco, andale mono, courier new;padding: 10px 12px; border: #ccc 1px solid; border-left-width: 5px; background-color: #fefefe; box-shadow: 0 0 4px #eee; word-break: break-all; word-wrap: break-word; color: #170;"

7.6制作一个文字标题

<code style="padding: 2px 4px; border: none; font-size: 13px; white-space: pre-wrap; vertical-align: middle; color: #c7254e;">row,column</code>

           

 7.7制作文字特效

style="box-sizing: border-box; outline: 0px; margin: 0px; padding: 2px 4px; font-family: 'Source Code Pro', 'DejaVu Sans Mono', 'Ubuntu Mono', 'Anonymous Pro', 'Droid Sans Mono', Menlo, Monaco, Consolas, Inconsolata, Courier, monospace, 'PingFang SC', 'Microsoft YaHei', sans-serif; line-height: 22px; color: #c7254e; border-radius: 2px; overflow-wrap: break-word; font-variant-ligatures: common-ligatures;"

        

8.给编辑博文可选表情选项——右击红块增加

<strong>🅰块级元素:</strong>

              

9.移动端开发自适应
