Active state and display:none causes link not to work - html

Consider the following fiddle: http://jsfiddle.net/GMA76/
On the links active state I want to replace the content of the a tag, then it should continue to follow the link. However when I style it as shown in the fiddle and here:
a div:first-child{
display:block;
}
a div:last-child{
display:none;
}
a:active div:first-child{
display:none;
}
a:active div:last-child{
display:block;
}
The link doesn't work the first time you click it. It only replaces the content and then it seems the redirection fails.
How would I fix that?

Browsers don't take well to content changing on the :active event. Even if it did work, a CSS-only solution would likely mean that the user wouldn't even see the change in content before the new page had loaded (or started to load with a white screen). I tested a lot with the :after pseudo-selector and the content property, but this didn't work either.
And rightly so. Changes to content should only be done with a language like Javascript. This is a logic issue and is outside of the scope of a styling language. Therefore, I would suggest using Javascript.
I've created a quick fiddle here using Javascript with jQuery (doesn't need jQuery it but it's easier) to switch the text in the link and then go to the new page exactly 1 second afterwards. This way you only need to have the original link in the HTML rather than hiding separate links with CSS. There are more flexible and extensible ways to do this if it's not just for one or two links but for the sake of an example, take a look at the fiddle.
This is the jQuery:
$(".switch-link").click(function(){
$(this).text("Test Two");
var href = $(this).attr('href');
setTimeout(function(){
window.location = href
}, 1000);
return false;
});
1000 is the delay between the text changing and the browser starting to load the new page, you can change this to suit your needs.

using target in css to keep color

I have the following example in http://jsfiddle.net/uA97K/
What I am trying to achieve is to keep the same colour on a selected tab as the hover. So when a user clicks on a tab, that selected tab will remain blue until another tab is selected.
I thought this could be done by using a:target but does look to be working.
#bar a:target { background: #00A3EF; color: #003366;}
Any ideas what I may be doing wrong?
With only CSS, you can't do it. But you can use jQuery, and an .active class for this:
http://jsfiddle.net/uA97K/1/
$('#bar a').click(function(){
$('.active').removeClass('active');
$(this).addClass('active')
});
This is, as already noted, impossible with CSS currently. It is, however, possible with plain JavaScript (albeit the following demonstration works only with browsers that support document.querySelector(), addEventListener() and the element.classList API):
function hashMonitor() {
var D = document,
active = D.querySelector('a.active'),
link = D.querySelector('[href="#' + D.querySelector(':target').id + '"]');
if (active) {
active.classList.remove('active');
}
link.classList.add('active');
}
window.addEventListener('hashchange', hashMonitor, false);
JS Fiddle demo.
Conceivably, under Level 4 of CSS (currently entirely unsupported in the wild) this could become possible, but until implementations appear it seems fruitless to speculate on how such selectors might be used.

document.querySelector().
element.classList.

Is it possible to hide the title from a link with CSS?

I have an anchor element with a title attribute. I want to hide the popup that appears when hovering over it in the browser window.
In my case, it is not possible to do something like this,
$("a").attr("title", "");
Because of jQuery Mobile the title will reappear after certain events occur (basically everytime the anchor element gets redrawn).
So I hope to hide the title via CSS.
Something like:
a[title] {
display : none;
}
doesn't work, since it hides the entire anchor element. I want to hide the title only. Is this even possible? The popup shouldn't display.
Using the following CSS property will ensure that the title attribute text does not appear upon hover:
pointer-events: none;
Keep in mind that JS is a better solution since this CSS property will ensure that the element is never the target of any mouse events.
You can wrap your inner text in a span and give that an empty title attribute.
<a href="" title="Something">
<span title="">Your text</span>
</a>
As per #boltClock's suggestion, I'll say I don't feel that a CSS solution is appropriate here, as the browser decides what to do with the title attribute of a link, or anything for that matter. CSS, to my knowledge, is unable to handle this issue.
As mentioned, using jQuery to replace the title with an empty string wont work because jQuery mobile rewrites them at some points. This, however, will work independently of JQM, and doesn't involve entirely removing the title attribute which is SEO important.
This works:
$('a["title"]').on('mouseenter', function(e){
e.preventDefault();
});
I changed my initial code of $('body').on('mouseenter') to this after testing. This is confirmed to work.
In CSS it's not possible, because you can only add contents to DOM (tipically with :before :after and content: '...';, not remove or change attributes.
The only way is to create a live custom event (es. "change-something"):
$("a").on("change-something", function(event) { this.removeAttr("title"); });
and trigger to every changes:
... $("a").trigger("change-something");
More information and demo here:
http://api.jquery.com/trigger/
http://api.jquery.com/removeAttr/
try to change your code using this
$(document).ready(function() {
$("a").removeAttr("title");
});
this will remove title attribute so the hint label won't be appear when hover on the link
$("#test").tooltip({title: false});
There title attribute default value is true, make it false.
This will work only in case of Bootstrap Tooltip
Full working pure javascript solution
var anchors = document.querySelectorAll('a[title]');
for (let i = anchors.length - 1; i >= 0; i--) {
anchors[i].addEventListener('mouseenter', function(e){
anchors[i].setAttribute('data-title', anchors[i].title);
anchors[i].removeAttribute('title');
});
anchors[i].addEventListener('mouseleave', function(e){
anchors[i].title = anchors[i].getAttribute('data-title');
anchors[i].removeAttribute('data-title');
});
}

Element not receiving style from one of its classes

Alright i have a button element as follows:
<button class='secondary row_1 col_1 not-sticky'>Button</button>
styling for secondary etc work, but it does not pick up the styling from 'not-sticky'. This is my basic styling:
.not-sticky { color:#FFFFFF; }
.sticky-state { color:#000066; }
When a button is clicked this code is run:
if ($(this).hasClass('sticky-state'))
$same = true;
//change old sticky classes to not sticky
$('.sticky-state').removeClass('sticky-state').addClass('not-sticky');
if (!$same)
$(this).removeClass('not-sticky').addClass('sticky-state');// chain our jQuery methods
Once this is run, the styling from sticky-state does work properly and the text color becomes #000066.
Also - through the use of chromes inspector i was able to verify that the classes are changing between not-sticky and sticky-state properly, just the styling from not-sticky is not showing at all
What could be making the not-sticky styling from not being applied at all?
Thanks
Here is the whole style sheet: http://staging.easyzag.com/style.css
It works in this fiddle: http://jsfiddle.net/c7XHX/
Don't know if $same was declared or not, but you always need to declare your JavaScript values.

Trying to hide an object / create a fold effect

I'm trying to create a rather unique effect. It's actually not that complicated, what I'm trying to do is build an experimental site, which I have already done. I just can't seem to figure out how to go about doing the final step.
So this is my site I'm tinkering with http://www.dig.ital.me/sandbox/about-me/
And what I'm trying to do is collapse the left-side bar that has the text in it : "Made in blah blah blah, etc." By clicking on the : " Click this to hide this " .
And I've tried going about doing an anchor link associated with a name link and calling the display:none when that link is clicked. However, it isn't working. So I thought I would try stackoverflow, on how I could about achieving this kind of effect where it collapses, and re-opens again.
#hide-option { color:#FFF; width:500px; height:500px; padding-left:170px;}
#hide-option:hover .fixedfooter {
display:none;
cursor:pointer; }
Here's a snippet of the hide-option div id. I've exhausted a lot of routes to try and achieve this effect but I cannot seem how to figure it out. I've tried the :onClick class, and nth-child classes, but nothing seems to work.
// Store the footer as a variable, so we don't have to keep calling jQuery's selector engine
// It's slower than a tortoise stuck in a traffic jam.
var target = $('.fixedfooter');
// Every time the hide-option link is clicked
$('#hide-option a').click(function() {
// If the left position of the target is 0
if(parseInt(target.css('left')) == 0) {
// Check the target is not animated and, if it is, animate off screen
!target.is(':animated') && target.animate({left: -751}, 250);
} else {
// Assume it's hidden, and put it back to the start
!target.is(':animated') && target.animate({left: 0}, 250);
}
// Stop the link being followed
return false;
});
JQuery, the JavaScript library, will solve it all for you.
$("el").bind("onclick",function(){$("el").toggle('slow');});
If you only want CSS3 (if you don't care about IE6-8), here's something you could try: http://jsbin.com/isunoz/6/edit
I've commented it as much as possible, I hope it helps :)
What I've done is to use a checkbox input to decide if the sidebar should be shown or not.
By putting the checkbox input element right before the sidebar element (div.fixedfooter) and changing your anchor (the arrow) into a label for that checkbox, I'm able to use the :checked pseudo class and the + selector to target the sibling element (in this case, the sidebar div.fixedfooter). If the checkbox is checked, the sidebar is moved out of the screen and if it's not checked, the sidebar is shown (left: 0).
For the animation I've used some css3 transition (transition: left .4s ease) :)

link to anchor near bottom of page

I'm doing some documentation where I make heavy use of anchors for linking between pages on a wiki.
see here:
http://code.google.com/p/xcmetadataservicestoolkit/wiki/ServicesExplained#Platform_Data_Structures
The feature that really makes this work well is when the browser shows the anchor at the absolute top of the pane. When it gets confusing is when linking to an anchor shows the anchor half-way down the page since the page is scrolled down all the way
see here:
http://code.google.com/p/xcmetadataservicestoolkit/source/browse/trunk/mst-common/src/java/xc/mst/utils/Util.java#227
My solution in the wiki (first link) was to put a blank image at the bottom of the page simply to make the browser show the anchor right at the top. Is there a better way to do this? Is there a way to do it in the second link (in which I can't add a blank image)?
Putting a blank image at the bottom of your page is a bad idea, since it will expand your document to a unnecessary height.
You could throw in some javascript to apply an effect to the anchor you just travelled to, to highlight it wherever it is.
Without altering the height of your document (i.e. adding extra padding at bottom), you'll always have this issue.
However, using bit of JS/jQuery, the user experience can be improved considerably:
On clicking a named anchor:
Instead of jumping in a flash (broswer's default behavior), add a smooth scroll
add an highlight to indicate current selection (this helps tremendously in 2nd case as the user can clearly see what is current)
Created a demo to illustrate the concepts: http://jsfiddle.net/mrchief/PYsyN/9/
CSS
<style>
.current { font-weight: bold; }
</style>
JS
function smoothScroll(elemId) {
// remove existing highlights
$('.current').css({backgroundColor: "transparent"}).removeClass('current');
var top = $(elemId).offset().top;
// do a smooth scroll
$('html, body').animate({scrollTop:top}, 500, function(){
// add an highlight
$(elemId).animate({backgroundColor: "#68BFEF" }, 500, function () {
// keep tab of current so that style can be reset later
$(elemId).addClass('current');
});
});
}
// when landing directly
if (document.location.hash) {
smoothScroll(document.location.hash);
}
$('a[href*="#"]').click(function() {
// utilizing the fact that named anchor has a corresponding id element
var elemId = $(this).attr('href');
smoothScroll(elemId);
});
You can create a absolutre positioned pseudo-element with a great height to targeted block using just the following CSS (for the second link in your post:
#nums td:target a::before {
content: '';
position: absolute;
height: 700px;
}
The height must be around the height of the viewport, so the best solution is to create these styles on the fly using js. But if you don't wan't to use js, just use height: 1000px or more — if you don't mind a gap at the bottom of course.
The best part: it's only CSS and there would be no gap when no anchors are targeted.
Edit: just a sneak peek into the future: if the vw/vh units would come to other browsers (now it's only in IE9), this could be awesomely done with just CSS using height: 100vh :)
You could use Javascript / jQuery to create a white div that has the necessary height needed to put your element at the top of the browser window, and you could even remove this upon scrolling away.
However I would highly recommend against doing so as this will expand your page where it isn't needed. It's a lot smarter to simply style the tag upon going there (through Javascript / jQuery) so it pops out to the viewer, for instance by setting the font-weight to bold or changing the background-color.
I would probably use a combination of jQuery and PHP for this:
PHP(somewhere right after your <body> element):
<?php
$anchor = explode('#', $_SERVER['REQUEST_URI']);
$anchor = $anchor[1];
echo '<div id="selected-anchor" anchor="'.$anchor.'"></div>';
?>
And then the jQuery:
<script type="text/javascript">
$(function(){
$('#selected-anchor').css('background-color', '[Whatever highlight color you want]');
});
</script>
Hope this helps.
