Stack is warning me this is a subjective question, and will likely be close, but I'm going to try this anyway.
I have a set of control buttons attached to pictures in a gallery. These are to be initially hidden, and toggle visible when the mouse hovers over the image. The question I have is this:
Should these buttons be set to hidden in the stylesheet or stay visible and be hidden by jQuery when they load? I want graceful degradation, so it seems like initializing this in the CSS is a bad idea if I want these to be visible if javascript isn't enabled.
On top of this, I'm using Ajax to load pages of these images. If I do this using the jQuery hide, it doesn't affect those that load from an ajax request, since it only triggers on $(document).ready(). I've tried using live('ready'), but learned that that event isn't supported in live().
So what is the best practice for something like this? It seems like there's a lot of pros and cons for doing this either way (css vs. document.ready), and if they're hidden by the default CSS, the buttons will toggle fine with ajax pagination. But if javascript isn't enabled, the functionality of the buttons will be lost. Does anyone have advice for this?
Note: I didn't mention it originally, but it is significant. I'm currently using fadeToggle() to accomplish my transition, which may be what's complicating this whole issue. The solutions so far all appear to work, but not so much when fading is introduced.
If you're trying to change the style of elements loaded via Ajax, it's almost like you're trying to hit a moving target. I would create two declarations in my stylesheet - one for hidden, one for visible - and then toggle them based on a class attached to the body tag (or any other containing tag).
Like so:
body .mybutton {
display:block;
}
body.loaded .mybutton {
display:none;
}
Then in your JS file:
$(document).ready(function() {
$('body').addClass('loaded');
});
This way, any elements that have the class name mybutton - current and future - will have the appropriate style applied.
You hide with CSS initially using display:none; then use jQuery's toggle() to show and hide again. This is the best way to do it. As for people that do not have JavaScript enabled, i wouldn't worry about that. They make 1% of users. Everyone have JavaScript enabled.

I'm very new to this and don't know how to use javascript or jquery and would prefer to avoid using it in all possible cases as I know it's not compatible in all browsers, takes time to load and can be disabled by users.
I've already made and designed the menu but would like the main heading in the menu to change to the submenu link when clicked on whilst keeping the rest of the menu in tact. How do I achieve this in css?
You can take a look at http://davidwalsh.name/css-target and use the css target selector (But it's not supported in IE - I haven't checked IE10 though).
but-
If you want to change the text or href attribute then, it's not possible in pure css (correct me if I'm wrong). You would have to use javascript. Jquery makes it easier to make your site support most used browsers, why not give it a go? I am certain if you get stuck, people on Stack overflow would gladly help you.
on a sidenote, css can also be disabled by the user (and not all browsers support all css features). Css and Javascript are in the same boat, because the browser dictates what is supported.
What CSS property should I change at this page to disable transparency of a share iframe which appears when Like button is clicked?
When you hover on that Facebook box after clicking Like button, it becomes partially transparent and if you move your cursor away from it, it becomes solid white. I want it to be completely opaque all the time.
Well, I see no transparency on that box, only for the fade-in effect when it opens, but once it's fully opened it's not transparent.
To answer your question, you can see for yourself using firebug (firefox) or the development tools (chrome/safari) which css rules apply to what element.
From what I've seen now, you can use the use these: fb_edge_comment_widget fb_iframe_widget which are the classes of the span containing the iframe, or you can use the iframe itself.
The thing is though, is that you should not hack that. Why? Since then you'll have to always check for updates facebook are making, changes that they do not update you about (API changes they update on the blog), if you fail to be aware of these changes it can "break" your code/style.
I was also having the exact same problem.
I am using an AddThis widget set, and I don't know if this was the case for you or not (it looks like you may have chosen a different solution as I can't see the Like button on your site).
I ended up using
.addthis_button_facebook_like {
opacity:1 !important;
}
but you would use whatever selector that wrapped your like button. if using the standard embed from Facebook, it would probably be
.fb-like {
opacity:1 !important;
}
Someone else was having a similar problem with a Send button, which got me on the right track.
See it working like it ought to here. I'm sure it had something to do with some conflict from other styles, or possibly AddThis, but it's working now!
Is there any way to style an internally-linked div when it becomes focused? Like say I've got a link at the top of a page that I internally link (<a href="samepage.html#more">) to a div further down the page (<div id="more">), when someone clicks to that div, is there any way to style it to show that it's focused (like I'd maybe use a change in its background color or give it a border when it's clicked to)? It's not really like giving it a hover styling, it's more giving it styling on active or on focus or something like that. Is there any way to do that?
I'm not sure if there's just no way to do it, or if I'm being dense and there's an easy way, but I'm not seeing it so far. Thanks.
You should bind a JavaScript function to the window.onhashchange event:
window.onhashchange = function () {
var hashloc = window.location.hash;
// hashloc is a string like '#focusDiv'
// .. manipulate DOM
};
This miniature working jsFiddle example uses jQuery, and adds a CSS class to the focused DIV when a hash change event occurs.
The event is bound using plain JS because jQuery doesn't natively provide this hook, which may not at all be supported for older browsers as noted by Matt. To solve this I highly recommend this jQuery plugin for simple hash events.
Divs don't have a focus property that I'm aware of, but you'd probably want to bind to an event when the hash in the URL changes, then apply the changes to the div with an ID of the value of the hash.
For example, bind to this event: window.onhashchange -- it will only work on modern browsers (ie8+, Chrome 5+, Firefox 3.6+, etc) without some tweaking.
Here is the scenario: I have a div which I pre-load into a page and automatically set it's display property to hidden. I use javascript to pop-up said div. The issue is when clients have CSS disabled they can see the DIV, obviously. What is the best way to have the div (or contents of the div) display only when my javascript function is called?
The best way I could think of is passing the raw HTML to a javascript var and then loading all the HTML using javascript, however, this is a bit slow(theres a decent amount of HTML) which causes the script to break when it tries to reference DIVs that do not exist yet.
any other more elegant solutions?
Thanks
You can wrap html comment tags around it:
<!-- <div>your stuff, which should be invisible</div> -->
Or remove it completely from the DOM
http://plugins.jquery.com/plugin-tags/html-comments
Maybe, here some related stuff
If CSS is disabled, then the only way to hide the div is to remove it from the DOM.
You can set an inline style on the div (not recommended but your case is an exception anyway).
You can use JS/jQuery on page load to hide the div but it'll cause the flicker effect (div wiil be visible momentarily until the JS runs to hide it).
You want to have a div on your page when the page loads so that users without javascript can see it, perhaps to indicate them that some of the site functionalities require JS to work.
If you need to use that div exclusively with JS then having it already on the page is a bad approach imho. You should create it on the fly, at least the content.
This way you will ensure users without CSS won't see it, while still being able to show it for the rest of the people with JS enabled.
Set the height of the div you wanna hide to zero using javascript.
$('#mydiv').css("height", "0px");
I am using AJAX modal popup in my project, but there is problem with it.
Now I decided to acheive similar behaviour using javascript
I am able to show popup using
document.getElementById('dv').style.display = "block";
Now I just need, how can I make background disable like in modal popup?
you create a div that spans the whole page but initial style is display:none; along with any other styles. i.e transparency 80% with background colour of black..
When you show dv change the display attribute of the div (above). Just make sure that the dv has a higher z-index than the background div and the background div has a higher z-index than the content on the page :)
Have you considered using a library for this? The most programmer-friendly and flexible I have found is NyroModal (jQuery based). The advantage of a library is it will deal with many subtle things that happen with modal dialogs, e.g. ensuring it works effectively across all browsers (and overcomes the various quirks around things like positioning), animating on and off, lightbox effect around it.
NyroModal lets you generate dialogs dynamically, whereas most libraries are geared owards simpler use cases such as "make all images clickable so they show up as lightboxed when the user clicks on them".
