Where CSS can exist physically in a HTML file

Sam Hobbs

I am learning CSS. I am having difficulty understanding it conceptually. I have a question about where CSS can exist physically in a HTML file. I think the following are the (at least the common)

uses of CSS in terms of where it can exist in the body.

Explicit use of styles as "class" and "id" attributes in elements
Inline style using the "style" attribute in elements
Style tags (in the body)

I know that style tags in the body is not common and that in the body HTML 5 only supports style tags with the scoped attribute.

I know that type selectors in CSS within style tags in the header can affect the specified element(s) logically but I am only asking about physical presence within the body.

Does that list specify (generally) everywhere that CSS can exist physically in a HTML file?

CSS is a language. Yes, there is no CSS tag. There is no "C#" in a C# program and there is no "CSS" in CSS. CSS is just an acronym to describe the language. You say there is no CSS tag but saying there is no CSS tag is like saying there is not C# statement or method in a C# program.

Do you understand what "Inline CSS" is? In HTML, Inline CSS is specified in "style" attributes in HTML elements. Do you understand that? The value of "style" attributes is CSS (the CSS language). That is one place that the CSS language can be in the body.

Another place that CSS can exist is as class names specified in the "class" attribute in HTML elements. The "class" attribute specifies a CSS class.

No i am not comparing CSS to C# i actually tried to gives you an example of Namespace, what my moto is to make you understand that the behaviour of Namespace is same as the behaviour of CSS.It's an logical container.
I visited your link, and the answer of your question i already given you in my first reply that their is no CSS tag like html tag, It's just an Naming given W3 consortium,nothing else.
And what ever style we are using that all comes under CSS,but css originally doesn't exit, rather all it's styling attribute exit like font-size,color,and etc.
Hope this make sense.

I have a web page that explains my question, see:

http://simplesamples.info/simplesamples.info/CSS/Where%20CSS%20Exists.aspx

That shows what I mean by:
- Explicit use of styles as "class" and "id" attributes in elements
- Inline style using the "style" attribute in elements
- Style tags (in the body)
You are right, there is no "CSS" tag anywhere.

Yes, I am familiar with C# but in C# classes have methods but CSS classes cannot have methods. In C# only declarations (such as using the "class" keyword) can inherit multiple interfaces but every definition (instance) inherits exactly the same as every other instance of the class. In CSS, class instances (such as in the "class" attribute) can inherit multiple classes. In other words, when you compare CSS to other languages, there are some really big differences.

If i am not wrong U are asking for where is the physical existance of CSS, if so then
To answer this question CSS full form "Cascading Style Sheet" that's the answer for this Question.It's just like a sheet which contain all the styling property.

It's nothing like that you can find CSS tag in html page rather then you have all the tags which comes under CSS.
If you are familar with C# programming language then the best example for your Question is Namespace used in C#, Namespace have not any physical existance but it's an logical container like folder. So like that CSS is container which contains different styling atrribute inside it.
Hope i tried to answer your question,if it's make sense then reply.
