CSS question

html,
body {
margin:0;
padding:0;
height:100%; /* 100 % height */
}

Above is a part of a CSS file I found in the Internet. I have been
searching in the Internet to find out what does the 1st line (html,)
mean. Can any one tell me what does it mean?

}

It contains a most spectacular comment. It is potentially useful for
misleading people, if the actual CSS code is later changed and the comment
is not. :-)

It means that you need to read a primer, a tutorial, or a book on CSS now.
It's a matter of very basic constructs in CSS, so if you needed an
explanation, you need a crash course in CSS before trying to understand
other people's CSS code (which is often much more difficult and much less
useful than writing good CSS code of your own).

In CSS, you specify that some declarations are to be applied to some
elements by listing selectors that refer to elements, using a comma as a
separator. At the simplest, a selector is just an element's name, like html
or body. Thus

html, body { something }

is equivalent to

html { something }
body { something }

(and the line break is irrelevant: it is equivalent to a space in CSS).

No, no... OP is wanting you to tell him about the html element.
It looks so strangely ephemeral.

Do you mean that OP does not know about HTML?

I know what you mean, and I guess you know what I meant.

That should be: html, body { *declaration(s)* }
The whole thing is a *rule* (selector followed by a declaration block).

Nothing wrong with what you were trying to say about grouping selectors.
