我想为我们的公司创建某些标准的CSS代码,并且作为品牌,我想以我的公司名称开头所有类名,并以-Cls结尾所有
<div class="Nam-StdCss-Cls"></div>
<div class="Nam-StdCss-Raduis-Cls"></div>
<div class="Nam-StdCss-Border-Cls"></div>
我也想允许用户使用其自定义CSS
<div class="Nam-StdCss-Cls menu"></div>
<div class="menu Nam-StdCss-Cls"></div>
我试图这样做,并且不允许进入菜单之类的自定义类。
[class^="Nam-"][class*="StdCss-1"][class$="-Cls"]{}
我尝试过,这不是检查班级名称的开始和结束
[class*="Nam-"][class*="StdCss-1"][class$=*-Cls"]{}
所以我想知道,我们如何才能检查类名的开始和结束 ,而不是整个字符串?
答案 0 :(得分:0)
基本上我们可以有4种情况:
仅具有所需的类:
<div class="Nam-StdCss-*-Cls"></div>
开始时有必要的课程
<div class="Nam-StdCss-*-Cls ... more-class"></div>
最后有必要的课程
<div class="more-class ... Nam-StdCss-*-Cls"></div>
在中间有所需的类
<div class="more-class ... Nam-StdCss-*-Cls ... more-class"></div>
您可以为每个选择器编写一个选择器,如下所示:
[class^="Nam-"][class*="StdCss-"][class$="-Cls"]{
color:red;
}
/*note the space after the class name---------v*/
[class^="Nam-"][class*="StdCss-"][class*="-Cls "]{
color:blue;
}
/* v---note the space before the class name*/
[class*=" Nam-"][class*="StdCss-"][class$="-Cls"]{
color:green;
}
/* v------space before and after---------v */
[class*=" Nam-"][class*="StdCss-"][class*="-Cls "]{
color:purple;
}
<div class="Nam-StdCss-Cls">aaa</div>
<div class="Nam-StdCss-anything-Cls">aaa</div>
<div class="Nam-StdCss-Cls ... more-class">bbb</div>
<div class="Nam-StdCss-other-Cls more-class ...">bbb</div>
<div class="more-class ... Nam-StdCss-Cls">ccc</div>
<div class="more-class ... Nam-StdCss-radius-Cls">ccc</div>
<div class="more-class ... Nam-StdCss-Cls ... more-class">ddd</div>
<div class="more-class ... Nam-StdCss-radius-Cls ... more-class">ddd</div>
<br>
<div class="more-class more-class">not !!</div>
<div class="more-class Nam-StdCss more-class">not !!</div>
<div class="Nam-StdCss more-class">not !!</div>
您应该注意,因为在某些特定情况下,这可能会针对不需要的元素,这是因为顺序对课程无关紧要。
[class^="Nam-"][class*="StdCss-"][class$="-Cls"]{
color:red;
}
[class^="Nam-"][class*="StdCss-"][class*="-Cls "]{
color:blue;
}
[class*=" Nam-"][class*="StdCss-"][class$="-Cls"]{
color:green;
}
[class*=" Nam-"][class*="StdCss-"][class*="-Cls "]{
color:purple;
}
<div class="Nam- StdCss- -Cls">aaa</div>
<div class="StdCss- Nam- -Cls">aaa</div>
<div class="-Cls StdCss- Nam-">aaa</div>
