This article mainly introduces the css layout naming when how to avoid underlining related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe that you read this css layout naming when how to avoid underlining article will have a harvest, let's take a look.

Friends who have used csshack should know that naming with an underscore is also a kind of hack. If you use a name like "_ style", you can make most browsers outside ie ignore the definition of this style, so it is not standard to use "_" as the delimiter when naming. There will be an error when doing a css check, so avoid using underscore naming.

To do this, we have to find a standard symbol that can replace the underscore. Of course, we don't have to use this kind of separator, it's just a matter of personal habit.

Do a small test and replace the underscore with "~", "$", "`", "&" and "-" respectively. As a result, only the "-" sign can be used, and the support for js is normal. Take a look at the test:

The following is the referenced content:

Css section:

The code is as follows:

. try-a {color:#00f;}

.try ~ a {color:#00f;}

.try`a {color:#00f;}

.try & a {color:#00f;}

.try $a {color:#00f;}

. try-b {color:#f00;}

.try ~ b {color:#f00;}

.try`b {color:#f00;}

.try & b {color:#f00;}

.try $b {color:#f00;}

Html section:

The code is as follows:

Try1

Try2

Try3

Try4

Try5

Js section:

The code is as follows:

Functionb () {

Document.getelementbyid ("a"). Classname= "try-b"

Document.getelementbyid ("b"). Classname= "try~b"

Document.getelementbyid ("c"). Classname= "try`b"

Document.getelementbyid ("d"). Classname= "try&b"

Document.getelementbyid ("e"). Classname= "try$b"

}

The result is that "try1" turns red and appears normal. However, in the definition of css, the id selector is often used. If you use "_" in the id naming of the page, you will inevitably have an underscore "_" in the css style, so you should also pay attention to avoid using an underscore in the naming of id.
