What is the simplest and most elegant way to simulate the hover pseudo-class for non-Anchor tags in IE6?
I am specifically trying to change the cursor in this instance to that of a pointer.
I think the simplest way is to use the hover.htc approach. You add the hover.htc file to your site, then reference it in your stylesheet:
body { behavior:url("csshover.htc"); }
If you want to keep things as clean as possible, you can use IE conditional comments so that line is only rendered users with IE6.
Regarding your request -- I am specifically trying to change the cursor in this instance to that of a pointer -- the easiest way is to specify cursor:pointer in your css. I think you will find that works in IE 6.
Try this to verify (where div can be any element):
<div style="background:orange; cursor:pointer; height:100px; width:100px;">
Hover
</div>
I would say that the simplest method would be to add onmouseover/out Javascript functions.
Another alternative that will fix many more issues in one go is to use IE7.js.
Another approach, depending on what the item is, is to add a non link anchor and set its display to block. Either put the anchor within or surrounding the item you want the pseudo hover behavior on.
Aside:
I actually already needed to swap the image anyhow
Make sure you take a look at Image Sprites. Sometimes its much nicer to use one image and "shift" the image then to use two separate images and "toggle" or "swap" between them. In my experience its been much nice when as user interacts with it is sometimes an advantage that there is a single request for the 1 image then multiple requests for multiple images.
I liked the mouseover/out best since I actually already needed to swap the image anyhow. I really should have thought of doing this with javascript to begin with.
Thanks for the quick answers.

Thanks for that link. I had never heard of this technique before and really like the idea.
I will definitely try that out and see how I fare with it.
If your willing to use JQuery, I would use Set Hover Class for Anything technique.

The question is pretty straight forward. Should I use CSS or JQuery when styling elements that are in the hover state (does one have any real advantage over the other)? To me, using JS seems like a hassle since the pseudo-classes are so easy to use. Thank you!
You should use CSS wherever possible; it's more efficient.
It also works better with property cascade and with elements created later.
Well it depends. If you want your website also displayed on mobile devices it is wiser to make a hover class and attach it with jquery because mobile browser handle hover very sketchy and different.
I stumbled upon this article
http://www.thefloatingfrog.co.uk/css/my-hatred-of-br-clearall/
When would one need to use that ?
Why is it evil ?
I don't understand the substitute syntax can you explain ?
Setting clear to both with not allow other elements to float on either the left or right side of the element. The class below is an easy way to add this anywhere.
.clear {
clear:both;
}
So when you want to clear something (that is, if you were to float the next element to the left, it would be below the current element and to the left, instead of left of it) you'd simply add the .clear class.
The problem with the following code is that if later on you decide that you don't want to clear everything after the 'something' class, then you have to go through your HTML and remove the br clear="all" wherever you have that 'something' class.
<div class="something">Cool content.</div>
<br clear="all">
<div class="other">Cool content again.</div>
Instead you could do something like this:
.something {
float: left;
}
.other {
clear :both;
float: left;
}
<div class="something">Hi!</div>
<div class="other">Hi again from below!</div>
That way if later on you decide to float all blocks with the 'other' class then you can just remove the 'clear:both;' from the CSS once.
I was about to post something snarky about you not reading the article, but when I saw that it was just a page of vitriolic rage with no explanation, I figured I'd answer.
It's because there are better ways of doing what you want to do -- namely, by using CSS in the way he does in the article, he has separated the semantics of the elements he's displaying from how he's displaying them. Why is this a big deal? Well, for one, he can more easily transform how his page looks when it's shown on different platforms (mobile, desktop) and media (screen, print, a screen reader for the blind), simply by editing CSS and not having to touch the document itself. This feature of CSS is pure gold.
On the other hand, if you use a construct such as this, you put in a hard constraint about your document's presentation that sticks around no matter what media or platform you're dealing with. What makes him so mad? Because once a developer has come in before him and used <br clear="all">, he has to take it out in order to get the benefits I just mentioned. That's why it's so frustrating. One bad developer can disable a whole host of development scenarios for every other developer who comes after.
As far as CSS goes, I have to say that it's a very difficult subject to just pick up without reading all about how it works. It's hard to explain how the clear attribute works if you don't understand floats. I had quite a hard time myself until I bought a great book on the subject.
When you have floated elements, the parent element can't calculate it's dimensions effectively and sizes incorrectly. Other items that follow floated items may also sit out of position. By clearing an element at the end of your floats, you correct alter this behaviour.
EDIT
Actually correct is probably the wrong word to use as this is what is supposed to happen and using the word correct suggests it is broken.
The author is just going off on a crazy rant about how the same thing can be accomplished using CSS on the DIV elements themselves. He's saying that br class="clear" is unnecessary.
It's also not a good practice because it mixes content with presentation. If a web designer wanted to re-theme the web application, he or she would need to modify the HTML to pull out all of the br clear elements, whereas if this was done as the author suggested, then the CSS files could be swapped out independently of the HTML, making their jobs easier and giving them one less thing to rant and rave about.
The rant is of course justified, as these simple, silly lines of code can actually cause a lot of headaches.
The idea is that your markup describes the information, and the CSS formats that information.
A dummy tag to clear floats isnt semantic, as it's only purpose is for layout reasons. There are other semantic ways of clearing floats that keep this separation. As commented below but here for clarity this is a good resource for semantically clearing floats http://css-tricks.com/the-how-and-why-of-clearing-floats/
My code creates CSS divs with dynamic names
i.e.
cke_record_body_19
cke_record_body_54
Is it possible to style all divs that contain the string cke_record_body_ in their name using CSS?
The best cross browser solution is to style them by adding a class to each div.
Can you just have your code give these divs a class="cke_record_body" attribute? Then you can just apply a style to them however you want and ignore the ids.
If you really have to this should work:
div[id*="cke_record_body_"] {
}
Keep in mind I believe this is CSS3 so I have no idea what current support is, but really this is the only way to do it in straight CSS without other libraries. If you are using jQuery or something see Nealv's answer.
sure:
$("[id^=cke_record_body]*").something()
I'm currently working with a set of links that are getting their background images replaced when they are focused, hovered over, and non-focused; but right now I also need to fix it so that when you hover a focused link you'll get yet another result. My searching hasn't found anything and my experiments with anything like:
a:focus:hover { background:url(image.url) no-repeat;}
have met with less than desired results. Does anyone know of way to simply do what I'm trying for?
This should work, but focus won't work in IE without a valid doctype, so I doubt :focus:hover will fare any better.
Solution found, that method does work; but only when you remember to include the class and sub-class names that you are applying to an item.
Is there a way to bold only part of the text in a drop down list option or is this not possible?
I know that you can style the entire option with CSS, but that is not what I am looking for. And HTML inside of an option tag does not render.
Here would be an example of a drop down list item:
SomeID - Description of ID
You cannot do this. The most likely solution you'll find "out there" would be to add a surrounding span with hard coded style, but neither IE (7) nor Firefox (3.0.12) honor this. In fact, if you look at the generated source in Firefox, the internal span is completely stripped out.
What you can do is use a JavaScript solution to give you the appearance of a select without actually using a select.
EDIT: And here's a great HOWTO on how to do it: http://www.devirtuoso.com/2009/08/styling-drop-down-boxes-with-jquery/
Not possible or at least not working cross browsers. If you really need this, you can create your own dropdown but I wouldn't recommend it.
