All too often I see something like this:

<style type="text/css">
<!--
css here
-->
</style>

In people's stylesheets. This is very very wrong. - Never use HTML comments in your style sheet.

HTML COMMENT:

<!-- qwertyuiop -->

ONLY use css comments in style sheets.

CSS COMMENT:

/* This is the only right way to comment CSS */

Why?

1. Putting in HTML comments was an early hack to prevent non css aware browsers from trying to parse the css.

2. It is not now, never was, and never will be part of the standard.

3. Some gecko based UAs are starting to "silently remove" anything between html comments.

3a: Yes I'm serious, we're currently alpha testing several UAs that do this.

4. The implications should be very obvious.

To repeat your css should look like this:

<style type="text/css">

css here

</style>


and not like this:

<style type="text/css">
<!--
css here
-->
</style>

This is very interesting to read.

1. If we are still working with older browsers that won't recognize the css and will possibly print our styles, then what do we do to eliminate this? (dont' be too hard on me, I'm only in training here[;)])

2. Also, if I don't put this into my homework, how do I explain to the instructor that this is not supposed to be, when all tutorials that I have read have instructed you to do so?

2.0 Suggest as sweetly as you may that she download a copy of the specs from W3C and try to find where in the spec it say that html comments in css is either syntactically or (more importantly) semantically correct.

I know that's not very helpful but if that's what she's telling you then she's giving you incorrect information, a lot of people are labouring under this delusion, but it is quite simply incorrect, and in my view it behoves a teacher to make extra efforts - if we can do it ......... (Said Jesper trying to be as tactful as possible )

- Of course there's nothing to stop you doing it just to keep her happy and then taking it out as a matter of urgency once you've finished the course. (This is me slipping in to "peacekeeper mode" a few weeks before I leave on a tour of peackeeping duty. - Thanks for the practice )

PS: Shirley put in a link to a posting she made that gives a good example of the right way to do it while I was typing - Thank you Shirley.

1. In regards to what Shirley posted. Isn't this a different means of commenting?

2. The one that Shirley has referred to is the one that you would use for commenting OUT code? Say I'm trying something not sure if I like it, but don't want to get rid of it while I try something else, I would just comment it out, and if I decide that this is what I want I would just remove the comments? As well as the reason that is mentioned in the thread that Shirley posted.

3. The commenting out that is referred to in your posting is to keep other browsers that aren't css compatible from seeing the styles?

Don't mean to be a stubborn student here, but lol, just want it all to make sense[;)]

How does this apply to using or not using? and is this standard or not standard?</edit>

quote:

CSS also allows the SGML comment delimiters ("<!--" and "-->") in certain places, but they do not delimit CSS comments. They are permitted so that style rules appearing in an HTML source document (in the STYLE element) may be hidden from pre-HTML 3.2 user agents. See the HTML 4.0 specification ([HTML40]) for more information

quote:

2. Yes, and that is indeed a very good use for it. But it is by no means limited to that. Comments are there to for example, help you remember which bit of the file refers to which selectors. EG:

/* Start of left navigation styles */

stuff

/*End of left navigation styles */

/* Start of right navigation styles */

stuff

/*End of rigth navigation styles */

/* Start of main content styles */

stuff

/*End of main content styles */

/* Start of hacks to cope with broken box model in ie5.5 styles */

stuff

/* End of hacks to cope with broken box model in ie5.5 styles */

and so on. Comments are just that. any text between this:

/*

and this

*/ will simply be ignored by the UA.

As for the <!-- comment--> this is for only below a certain html. Not for use with xhtml and html 4.0? Therefore, if you are using the most current coding then you should not use the previous mentioned comment. wheww. what a mouth full.[;)]
<edit> hoping that I have this correct!</edit>
