:focus selector in CSS - css

JSFiddle (The *:focus rule is to illustrate which element is marked as having focus.)
What I'm wondering is why, when I click a menu item, it gets the focus... but clicking a menu item does not give it focus.
What's wrong with the CSS to make it behave this way?

focus is generally only for elements that can receive keyboard or other input, so by this heuristic lis don't qualify. This question has more about it..
In the specs, CSS doesn't explicitly define what elements can be in those states, so it's hard to come up with a set rule for what can and can't be set to focus.
What might work for your purposes is active, which you can view here.

There is a small trick - if you want an item which not have focus anabled by default you should make it tabbable by seting its tabindex="N" - N is a number. As simple as that. if you add tabindex to your clickable items they will get focus when you click. If a tag can be tabbed it have to be able to get focus. Adding tabindex attribute to all nodes of the menu is very simple if you have jQuery loaded:
$(function() {
$('#navbar *').attr('tabindex', '1');
});
end everithing comes in place. You can do it using pure JavaScript of course.

Button highlighted after click

I want my application's buttons to be green only when I hover over them. Currently, they are green after I click one of them, until I click something else.
For instance, this button is green after clicking on it and before clicking somewhere else.
What's the name of this effect?
I am now looking over my css files, trying to find this effect and replace it with hover so that the buttons are green only when I hover over them.
My guess is that it is applying the style to the :focus pseudo-class.
The :focus CSS pseudo-class is applied when an element has received
focus, either from the user selecting it with the use of a keyboard or
by activating with the mouse (e.g. a form input).
Alternately, the style might be applied by JavaScript in response to click/focus events, either directly to the element, or by adding a class to the element.
As mentioned in the comments by #AdrianoRepetti, use dev tools to help identify how the style is being applied.

appear and disappear effect for div by clicking on it

I can't understand how to make something like in this site: __smashingmagazine.com
If u resize the window, the search will be with a button. So... try to click on this search icon... the new div will appear with search input. and pay attention to the behavior of it: no matter what u gonna do next this div won't hide it self, but only if you click on 'x' that appear instead of search icon... and this is pure css, right?! how this possible...
I found this article:
Click here
but the behavior is very, very different... and i don't like it at all.
Any idea how to make it work like in the site above? anything would may help!
Thanks!
The example from Smashing Magazine uses the :target psuedo class to change the CSS of the elements when an anchor is clicked. Here's a simplified breakdown of how they've achieved that behaviour.
The anchor is configured to set a fragment identifier in the URL, in the case of Smashing Magazine this is #ms. The have an anchor like this:
Search
When clicked the fragment identifier is set to #ms, they then use this to make the search appear using the :target psuedo class.
#ms {
display: none;
}
#ms:target {
display: block;
}
When the fragment identifier is set to #ms, the :target styles are activated, displaying the search.
Here's a simple example: http://jsfiddle.net/we76L66h/
They are using :target with children (#ms:target + div.example) to also change the styling of children within the targeted element. This is how they make the button change to a "close" button when the #ms fragment identifier is set.

CSS Hover style remains after mouse is no longer hovering

The following happens in Safari Version 7.0.1 and IE8.
Steps to reproduce the problem:
http://goo.gl/lP3Ky1
Problem:
The row's hover state remains after dismissing the popup menu, and it will not go away no matter where the mouse is, until you hover over it again.
What is the expected behavior?
The row's hover state should go away after dismissing the popup menu.
Does anybody know a fix for Safari Version 7.0.1 and IE8? I would be okay with some manual way to "untrigger" the css hover state.
This was an interesting issue to solve. And while the solution is a bit hacky, it works. After setting the HTML to "boo" we clone the entire row, insert it, and remove the old one:
$(function() {
$("table").on("click", "td", function() {
$("#menu")
.clone()
.one("click", function() {
var $td = $(this).closest("td"),
$tr = $td.parent();
$td.html("boo");
$tr.clone(/* true */).insertAfter($tr);
$tr.remove();
return false;
})
.appendTo(this)
.show();
});
});

Here is a workaround - http://jsfiddle.net/3BUaT/11/ . After going through many stackoverflow posts, understood that it is not possible to remove css pseudo class from javascript. So definitely a work around was necessary.
I'm using
tr.hovered td {
background-color: lightblue;
}
instead of regular CSS hover state.
The problem is that when you click on an li in menu, it's not exactly triggering mouseout event from CSS in safari. Technically speaking, you did not actually took your mouse out of the element. It's just that the element was removed. This seems like a bug in safari.
Its not browser's fault. Its yours. You are appending the menu list to the row. So the menu list is a child of the row. So if you hover over child, the parent will also be in hover state.
I've updated your jsfiddle:
Jsfiddle;
$(function() {
$("td").on("click", function() {
$("#menu")
.clone()
.one("click", function() {
// this is key to reproduce it.
$(this).closest("td").html("boo");
return false;
})
.appendTo($(this).parent().parent().last())
.show();
});
});
You are appending the div #menu to the td with your function. Now the CSS is going to apply the hover state to the td when you mouseover either the td or the appended menu. Hovering over the menu applies the tr:hover td css, because the menu is now part of the td.
OK, so here is my proposed solution which takes the points from my comments (on Tejas Jayasheel's answer) into account: JSFiddle
The differences are:
#menu is not cloned and not added to the table cell, but instead just repositioned (so the element is also only displayed once)
CSS hover only applied if the 'no-js' class is present in the HTML element (need to be added in your original file)
otherwise hover effect is achieved by applying the class "clicked" to the cell
additionally when menu is already visible the hover effect is "disabled" by toggling another class on all TD's
clicking outside the menu on the already "clicked" cell will close/hide the menu without any further action
.no-js td:hover,
td.hover-enabled:hover,
td.clicked {
background-color: lightblue;
}
What is the expected behavior? The row's hover state should go away after dismissing the popup menu.
Maybe ...! But keep in mind that you are heavily "confusing" the browser by removing the hovered element from DOM. I guess that Safari and IE 8 simply "do not recognize" that former hovered part isn't hovered anymore. This may or may not be a "bug". But at least it is "bad practice/ writing style" and should simply be avoided!
Does anybody know a fix for Safari Version 7.0.1 and IE8? I would be okay with some manual way to "untrigger" the css hover state.
The "fix" is shown in my example. It is a common recommendation to add, remove or toggle classes when it comes to scripting and hover. By doing so you avoid the "problem" at all. Because even in future versions of any browser the behaviour in such cases is "unpredictable" at best.

Collapsible dropdown menu - Set background for menu in active state?

First, please take a look at this pen showing just the menu + the code (preview the menu here).
Coming to the point: In the navbar that you see, clicking on the "Channels" menu shows the menu item sliding out. The problem is, the menu's background doesn't represent its active state (i.e. #fff background and #222 color).
Setting the background-color when the mouse is hovered on the menu, is easy. But this one's tricky. I did try, :active selector to no avail. Any ideas?
SCREENSHOTS:
You could add a class to the li once the menu is open and remove it again.
BTW: :active works for the moment you click on it.
Since it appears as though using jQuery to add/remove a class is the only way to go, I went ahead with it. Here's the code I used.
jQuery(document).ready(function($){
$('.menu-item > a').click(function(){
$(this).toggleClass('selected');
});
});
The code finds the link element a one level down the element with .menu-item class (li in my case), and adds/removes class .selected to the link element.
Here's a fork of the original pen with the menu functioning the way I intended it to. You can preview the new and functioning menu here.
(Full credit to the code provided in this question. More info in the official jQuery documentation.)
UPDATE: You might find this answer extremely helpful (a better, simpler solution).
Example code:
jQuery(document).ready(function($){
$('.collapse').on('show hide', function () {
$(this).siblings("a").toggleClass('selected');
});
});

jQuery click class change IE weirdness

I may be trying to get too fancy on this one.
I have a pair of radio-like buttons in a row with a divider between them with background images. When one of the 'buttons' is clicked, I change its class. The CSS for the divider is keyed to the classes of the buttons on either side to select a background image. I am doing this with CSS 'sibling' selectors.
I have jQuery .click events tied to the 'buttons'. the first thing they do is clear the 'selected' class from the other button and set it on the button that was clicked.
For example, if the LEFT button class='selected' and the RIGHT button is not, the divider between them will get a blue background. Click on the RIGHT button and it gets class='selected' while the LEFT button's class is cleared. The divider turns red.
This works in IE, FF, Safari, etc. But IE is odd (IE7) - it will only reflect the divider background change when I mouse OFF the button I clicked! That is, in the example, the RIGHT button gets class='selected' and changes immediately on the click. But the divider stays blue until I mouse off the button, then it turns red.
The class itself IS changing and the button's appearance changes as a result. It's only the neighboring stuff that doesn't!?
It reminds me of my old VB6 days when you had to periodically call 'DoEvents' to get Windows to make UI changes. Could there be something similar here for IE?
I have no idea why this helps, but adding .hide().show() to a selector that includes the stuff that changed class seems to make it update.
I've read that using setAttribute to change the class will force IE7 to re-render the styles. Try that, and if it still fails, I've solved a similar IE7 problem by rewriting the html, which forced IE7 to re-render (using jquery):
if ($("html").hasClass("ie7")){
var tempHolder = $("#ajaxresults").html();
$("#ajaxresults").html(tempHolder);
}
As for giving the html or body tag the ie7 class, I recommend taking a look at html5boilerplate.com. If for some reason you can't use their solution, the jquery for it is:
if ($.browser.msie){
if ($.browser.version < 8){
$("html").addClass("ie ie7");
}
else {
$("html").addClass("ie");
}
}
