Hi, people. How are ya? Would you please see this:

<style type="text/css">
body
{ background-image:
url("../images/bgdesert.jpg");
background-repeat: repeat-x}
</style>

What does this "background-repeat: repeat-x" mean? My background was filled with image but after putting this css in, it was filled only certain place. Why? I thought this css enabled me to fill something small repeatly.

"background-repeat: repeat-x" means that the browser will repeat the background image horizontally only.

ID selectors are like class selectors and are written in the same fashion other than the fact that classes start with "." while IDs start with "#". Typically classes are used several times in a page while IDs are normally only used once per page. Class selectors simply define CSS objects to be used over and over in a page to simplify the code while ID serve a greater purpose. IDs are usually intended to define CSS objects for use with Javascript to create various DHTML effects.

I hope that helps ya out.

Hiroki: The specs are a good place to read up on this as they explain things well and with diagrams:

And these are a must read if you're going to delve into CSS -

However, it seems you are trying to move a bit too fast for your own good Hiroki. Try getting the basics of HTML down first...then move on to CSS.

Just as a minor clarification on what Shard said, ID selectors are not normally used only once per page, they are always used only once per page. I'm pretty sure it won't work if you try to use an ID more than once (although I don't think I've actually ever tried that).

Not trying to be pedantic, just wanted to clear that up to prevent Hiroki from running off and doing something that might get him hurt.

I would also recommend taking it slow. No need to rush things.

Well... *ID's* are only used once per page. Meaning that the "something" in the HTML attribute id="something" can only be used once, the next one must be id="somethingelse", etc.

However, *ID selectors* can be used multiple times. That is, your CSS can contain:

#something {blah blah}
#something {more stuff}
#somethingelse, #something {this applies to multiple elements}

Heh... yup, once again, Slime saves the day. That's what I meant to say (and probably what Shard meant to say, too).

I figured it was; I just wanted to clear up a potential vocabulary issue which could come back to haunt us =)

Yeah, that's what I was going after too. And just to clarify my first post a bit... I'm still relatively new to CSS. What I said in my first post was an indirect quote from the book "DHTML and CSS for the World Wide Web" by Jason Cranford Teague. I didn't feel the need to quote directly because I felt I could sum up the idea in the book with my own words. Anyway, the direct quote is:

quote:
...unlike a class, an ID should normally be used only once on a page to define a single element as an object.


I just wanted to clarify where my info came from. Sorry if I mislead ya Hiroki.

That's interesting, Shard. I wonder why the "normally" got stuck in there. I'm guessing that it's one of those unnecessary modifiers writers stick in for no good reason (like "literally"), but I can't be sure.

Just to clarify, though (Slime, maybe you could help us out again?), IDs can only be used once, right? Is there a special situation where you can (or should) use them more than once? I'm not trying to muddy the waters, but that "normally" has gotten me a-wonderin'...

Maybe there's some really obscure case where you have two XHTML documents within a single XML document, and there's the same element with the same ID in each of them... but I'm skeptical. I'm pretty sure it's just an unnecessary modifier, as you said =)

This one had me a little confused. Thanks for pointing us in the correct direction Suho, Slime, and DL.
