CSS hover effect on ajax content and mobile devices - javascript

I've build a quiz. Each question has 2 answers. When the visitor answers a question, the next one is loaded using Ajax. Before the questions are loaded the visitor has to click a start button first, so the HTML for the questions isn't included in the initial page load.
The problem is when a question is anwsered, the hover effect from the previous question is still active when the next one is loaded.
For example: I anwser question 1 with "B" > question 2 is loaded > the hover effect is active on button B for question 2
I've included an image to make this more clear.
I only have this on mobile devices (iPhone, iPad,...) but not on my laptop.
I've done some research if I can alter the hover pseudo class, but apparently this isn't possible using javascript.
I think the problem is that the HTML is the same for each question, so the hover state stays active for the css class when the first question is answsered.
I can't supply a jsfiddle because the questions are entered as a content type in Drupal, and I can't include the entire Drupal in a fiddle. But here is the HTML and CSS.
<div class="quiz_st_content form-wrapper" id="ajax_form_multistep_form_content">
<div class="quiz_st_content_answer form-wrapper" id="edit-a--2">
<div class="quiz_st_content_answer_info_wrapper">Option A</div>
<div class="quiz_st_content_answer_button_wrapper">
<input class="quiz_st_content_answer_button form-submit ajax-processed" type="image" id="edit-answer-a-2" name="answer_a_2">
</div>
</div>
<div class="quiz_st_content_answer form-wrapper" id="edit-b--2">
<div class="quiz_st_content_answer_info_wrapper">Option B</div>
<div class="quiz_st_content_answer_button_wrapper">
<input class="quiz_st_content_answer_button form-submit ajax-processed" type="image" id="edit-answer-b-2" name="answer_b_2">
</div>
</div>
</div>
CSS
input.form-submit.quiz_st_content_answer_button {
margin: 0;
border-radius: 50px;
-moz-border-radius: 50px;
-webkit-border-radius: 50px;
height: 30px;
width: 30px;
padding: 20px;
background: #ccc;
}
Hover
input.form-submit.quiz_st_content_answer_button:hover {
background: #ba043f;
}
As mentioned above, this only happens on mobile devices. I've been bashing my head at this for hours now and I'm clueless on how to resolve this.
If anyone could help me, or point me in the right direction it would be greatly appreciated.

When I was working with mobile devices I added
ontouchstart=""
to the body tag like so:
<body ontouchstart="">
This made the hover pseudo selectors not act so awkwardly for me, it may be worth a shot.

I was able to fix this. Well,..its not really a fix because the hover state is still active, but I overwrite the color with the default color on touch devices, like so:
$('.quiz_st_form,').bind('touchstart', function(){
$('body').addClass('touchdevice');
});
So when someone "clicks" on the quiz start button on a mobile device, my body gets the class touchdevice and I "remove" the hover with CSS, like so:
body.touchdevice input.form-submit.quiz_st_content_answer_button:hover {
background: #ccc;
}
Technically the :hover state is still active, its just not visible anymore.
I don't really see a better way on fixing this at the moment. If someone does, please let me know.

Background colors not touching from two lines of text

I'm just trying to get the backgrounds touching on their long edge; like in this code, but with the two blues touching.
the code i have:
.header h1{ background:#0060D3; padding:10px; text-align:center}
.header h3{ background:#00CBFF; padding:10px; text-align:center}
<div class="header">
<h1>Page Name!</h1>
<h3>Subheading!</h3>
</div>
You have to normalize the css (overwrite the default states of padding and margin properties).
* {
margin: 0;
padding: 0;
}
.header h1 {
background: #0060D3;
padding: 10px;
text-align: center
}
.header h3 {
background: #00CBFF;
padding: 10px;
text-align: center
}
<div class="header">
<h1>Page Name!</h1>
<h3>Subheading!</h3>
</div>
As much as Kind User's answer solves your problem perfectly, you will still find yourself having to ask for help again next time a similar problem occurs. So rather than attempt to answer your question directly, I will explain how to figure it out for yourself.
Your browser will have an inspector (usually right click and choose Inspect from the context menu). I often use Firebug which is an extended inspector you can install as a plugin, but it is not essential for this task and the one built into your browser will suffice.
Click on the button on the top left of the inspector that looks like a cursor over a box, then click on any element on your screen to select it.
You will see under 'rules' all of the CSS rules that are currently affecting that element. Selecting the 'box model' tab will allow you to see the size of the element itself as well as the padding, border and margin on each side. Hovering your cursor over the element will also highlight each part of the box model separately so you can easily tell that the white space you saw was part of the margin.
To test this theory, you could go back to the rules tab and create a new rule stating margin:0px; and you will immediately see the effects. This is an effective technique for checking what CSS changes would appear to do before adjusting your actual file.
Side note: Just for clarification, although I would like to think it was obvious, I never make such assumptions. Any changes made in the inspector are entirely non-persistent in that they will not be saved in your file. If you refresh the page it will reload from the file and any changes made in the inspector will be gone.

Place a div at center of another with JQuery

I've a personal project to learn more about HTML/CSS/JS.
But I got a problem with it.
I have two divs in my <body>, each one with 2 circular concentric div. One is placed on the center of the area, the other one not.
<div id="sphaea_bloc">
<div id="actor" class="actor_locked">
<div class="actor_extern_locked"> </div>
<div class="actor_intern_locked"> </div>
</div>
<div id="lock" class="lock_locked">
<div class="lock_extern_locked"> </div>
<div class="lock_intern_locked"> </div>
</div>
</div>
The base placement is good.
The second step is to add drag'n'drop with JQuery, and it works fine. The aim is to drop the little div into the bigger div.
When it fails, it correctly returns at a base position.
But now, when the drop is good, I want to place with JQuery the little div in to center of the bigger div (making 4 circles concentric).
I searched for a long time but I didn't manage to do it without the problem : I've always a little offset between my 2 divs... And I'm not able to understand why.
Here is the fiddlejs link :
FiddleJS link
Someone can help me to find the problem, and why my little div is always inside the bigger but with an offset ?
Thanks in advance !

i have did like below, and its working, it will be centered even if you change with and height of divs:
.actor_locked {
position:absolute;
left:-9999px;
right:-9999px;
top:-9999px;
bottom:-9999px;
display: block;
margin: auto;
width: 60px;
height: 60px;
border-radius: 50px;
}

Hide the caret in an HTML texbox

So, this is a design decision that many of you may find odd. I would like to hide the caret from appearing in a textbox on a webpage but I want the textbox to remain active.
I was surprised to find that CSS does not actually offer any functionality for custom carets, admittedly it's nothing I've ever had the need for in the past but I thought that surely I wouldn't be the first to want to do this.
The best way for me to explain what I have done is by my showing you the website. www.hududandescape.com
As you can see, I have created my own custom caret which just blinks at the end of the text box that has been styled to blend in with the background. The textbox always keeps focus so there is no risk of users not being able to type in it.
My issue is that the caret that comes with the text box is still blinking. I have fixed this in Chrome and Safari by putting a small black box over the top of the very end of the box, thus covering up the caret. This solution is not ideal however and it does not work in Firefox or IE.
Your solutions, no matter how creative, are highly welcomed :)

I'm not sure, but try something like this. Idea is simple, i think you'll understand reading the code
<style>
input#top {
width:0px;
border: none;
}
#show-input{
border:1px solid #000;
width: 100px;
height: 25px;
}
</style>
<input id='top' /> <!-- 'hidden' -->
<div id='show-input' ></div> <!-- show input -->
<script>$(function(){
$("#show-input" ).click(function(){
$("#top").focus();
});
$("#top").keyup(
function(){
$("#show-input").html($(this).val())
})
})
</script>

JQuerymobile on an iPad: vclick triggers a scroll to the top of the page, then executes the vclick

SUPER SHORT VERSION:
Elements on a jQuerymobile-based html5 webapp don't respond directly to vclicks on an iPad. Instead, they silently scroll to the top of the page and trigger a vclick on whatever's under the same region of the screen.
LONG VERSION WITH PICTURES AND CODE:
I'm using JQuerymobile and I'm having a problem with my page responding to some vclick events when I'm using my iPad. I've got a page with a bunch of elements that are bound to respond to vclick events. If everything fits onto my iPad's display without scrolling, everything works perfectly. If I need to scroll to see the element I want to click, I get the following behavior:
I tap my finger where the red circle is here:
The page flickers and the page responds as if I clicked the area in the little blue circle:
(blue circle image redacted for lack of hyperlinks to noobs (It's Q43ri.png on imgur)
I was confused as to what the heck was happening until I superimposed the screens:
So when I click one of my divs, it seems like it's paying attention to the coordinates I click on the display, but then scrolling to the top of the window and actually executing the click from that perspective. How do I fix this?
Here's the html for that section of the page:
<div id="inventoryPageContainer" style="padding-right: 100px;">
<div id="inventoryDisplayHeaders">
<div class="inventoryPageName inventoryPageColumn header">Name</div>
<div class="inventoryPageQuant inventoryPageColumn header">#</div>
<div class="inventoryPageWt inventoryPageColumn header">Wt.</div>
</div>
</div>
<div id="inventoryTemplate" class="inventoryPageRow" style="display: none;">
<div class="inventoryPageName inventoryPageColumn">Template Item Name</div>
<div class="inventoryPageQuant inventoryPageColumn">#</div>
<div class="inventoryPageWt inventoryPageColumn">X lb</div>
</div>
<div style="clear: both; border-bottom: 2px solid black;"></div>
All of the divs are clones of that inventoryTemplate item. If you need the CSS for that (I don't know man, I'm trying to give anyone reading this all the info I've got):
#inventoryPage .inventoryPageName {
width: 100%;
}
#inventoryPage .inventoryPageQuant {
width: 50px;
margin-right: -50px;
vertical-align: middle;
}
#inventoryPage .inventoryPageWt {
width: 50px;
margin-right: -50px;
right: -50px;
vertical-align: middle;
}
Here's the event binding code:
templateCopy.find('.inventoryPageName').text(row.itemName).bind('vclick.inventoryPage', { row: row }, generateItemDescriptionDialog);
templateCopy.find('.inventoryPageQuant').text(row.quantity).bind('vclick.inventoryPage', { row: row }, generateItemQuantityDialog);
generateItemDescriptionDialog and generateItemQuantityDialog both set some values on some dialog pages and then trigger the dialog pages to show with $.changePage("#thepages").
So uh.. why's this happen and how do I make it not happen?
(It's an RPG character sheet webapp if anyone's wondering why I'm cataloging weapons and guns.)
I think my problem was how I wrote my event handlers. I went through and added:
if (event.preventDefault)
event.preventDefault();
to the beginning of each handler and made sure the handlers returned false. Admittedly, I don't know precisely what this did, so I'm cargo-culting a bit here, but it did solve the problem.

Why is this DIV rendering with no dimensions?

http://clifgriffin.com/blockade2/
Ok, I have an unordered list that serves as a list of menu links. In each li there is a div that is set to absolute positioning, bottom: 0. The idea is you hover over the link in the li and jQuery animates the height to show the hidden menu div.
It's a simple concept, but I am apparently confused.
The issue I'm having is that the div that contains the slide down menu doesn't take up any dimensions (according to Firefox and Chrome's calculated style information) when I put it in the li. If I put it anywhere else on the page it renders PERFECTLY. You can see what I mean from the link. The gray menu looking thing at the top is how it is supposed to render inside the li but doesn't.
<div class="ram">
<div class="gray_middle">
<ul>
<li>Guest Services</li>
<li>Concierge / Local Attractions</li>
<li>East Restaurant</li>
<li>Aquarium Lounge</li>
<li>Health Club</li>
<li>Sandcampers Program</li>
<li>Treasure Chest Gift Shop</li>
</ul>
</div>
<div class="gray_bottom">
<img src="images/top_menu_slidedown_gray_bottom.png" />
</div>
There is a bit of javascript going on that is supposed to find the height of the menu div and set the id of the containing li equal to the height so that it can be referenced later. Doesn't matter...the point is, when the div is in the li, its computed height is 0. When it is outside, it's correct.
Any ideas?
This is driving me absolutely batty. I have never had this many issues with something so simple.
Thanks in advance,
Clif
P.S. I added some HTML comments to the destination so that you can better see what I mean.
Absolutely positioned elements are "outside" of a container and can't really determine its size.
Relatively positioned elements impact container size (and content flow) but then they move elsewhere.
Also, for absolutely and relatively positioned elements, you should always give an explicit X,Y position. This avoids some rendering differences, cross browser.
Anyway, I made the following CSS changes and that submenu seemed to render OK on FF 3.6.4:
For <li id="49"> add: height: 230px; overflow: hidden; .
For div.subMenu add: top: 17px; and delete: bottom:0; .
For gray_middle add: height:160px; top:0; and delete: padding-top:20px; .
When you absolutely position an element, it won't expand the size of it's container to the size required to accommodate it.
EXAMPLE
HTML
<div id="outer"><div id="inner">In</div>Out</div>
CSS
#outer {
background-color: red;
}
#inner {
width: 100px;
position: absolute;
top: 100px;
background-color: blue;
}

Hi clifgriffin Had a quick look at you HTML, shame you didn't give us the CSS aswell, but ... there are a few things I'm not sure on - the header says generator WordPress 2.9.2 but the html does look like "familiar" WordPress. If it is WordPress generated then check the wp_list_pages & wp_list_categories tags you are using. Also I serously recommend an upgrade to WP3.0 as it has MUCH more functionality (custome post/page types etc) plus a "built" in menu function.
I think you may be using too much CSS. Most of what you want to acheive can be done with a lot less.

Concierge / Local Attractions
East Restaurant
Aquarium Lounge

Sandcampers Program

You can then give the ul an ID (remember ID's need to be unique) this will help with any Java you want to use also add to your ram class with a background image class images/top_menu_slidedown_gray_bottom.png. As you use the ram class again without the image. e.g. <div class="ram backgroundimageclass"> You are then saving a lot of "code" and download times etc.
If you give the ram class the attribute "position: relative;" you can then give the UL id the attribute "position: absolute;" the li's can be styled such as
ul#ID li {line-height 30px; etc ...)
ul#ID li:hover {line-height 30px; etc ...)
ul#ID li:hover a {line-height 30px; etc ...)
and so on.
Ohh forgot ... also why not add this code in the head
<meta http-equiv="X-UA-Compatible" content="chrome=1">
And this just after the tag

This allows "detection" of the browser and gives them the option (if not installed) to use Google Chrome Frame, you can:
Start using open web technologies - like the HTML5 canvas tag - right away, even technologies that aren't yet supported in Internet Explorer 6, 7, or 8.
Take advantage of JavaScript performance improvements to make your apps faster and more responsive. Enabling Google Chrome Frame is simple. For most web pages, all you have to do is add a single tag to your pages like above and detect whether your users have installed Google Chrome Frame.
If Google Chrome Frame is not installed, you can direct your users to an installation page.
If Google Chrome Frame is installed, it detects the tag you added and works automatically.
Cliff Just "totally" realised what you are trying to do here - sorry took so long to "twig"
OK you can do this with much more ease than you are trying to do at the moment. All it needs is a little JQuery and some basic CSS. No need to positions absolute etc.
In your CSS use { display: none; } for the class="subMenu" as you know this will "hide" it, I might also be tempted to do the same in your JQuery functions to be "doubly sure". Then in the JQuery create a mouseover effect (mouse over "better" than hover) for the class top_menu_links (I think you could take out the classes "aco" and "white_middle" or at least combine them in the css for the relevant ul) to show the .next('ul); you can slide it etc. Then a mouseout function on the ul. That way the ul stays visable until a mouse out event. I have done this quite successfully on a WP theme to display a "dynamic" list of categories on a mouse over event on a div made to look like a button. Sorry don't have the code to hand but will look later and "pass it over"
In addition you can set the ul background image as the approp. <img src="images/top_menu_slidedown_white_bottom.png" /> (or grey) just by setting it to background position: bottom repeat: none; and a bottom padding the height of the image. No need for alt tags etc.
Sorry been "out for a bit" anyhow here is a code I have used to "recreate" your bottom menu. It doesn't do as you suggest it closes after either a mouseout of the "menu item" or the "submenu". To get it to work on the top menu, just change the position from bottom to top:
$(document).ready(function() {
$('.indexMenu').mouseover(function(){
$(this).children().show();
$(this).children().mouseover(function(){
$(this).children().show();
});
});
$('.indexMenu').mouseout(function(){
$('.sub_menu').hide();
});
});
Here is the "html"
<div class="indexMenu">
Menu 1
<div class="sub_menu">
Item
<br />
Item
<br />
Item
</div>
</div>
<div class="indexMenu">
Menu 2
<div class="sub_menu">
Item
<br />
Item
<br />
Item
<br />
Item
</div>
</div>
<div class="indexMenu">
<div class="sub_menu">
Menu 3
<br />
Item
<br />
Item
<br />
Item
<br />
Item
</div>
</div>
<div class="indexMenu">
Menu 4
<div class="sub_menu">
Item
</div>
</div>
Obviously you can "use" any thing in submenu a ul,ol, etc...
And the "simple CSS
.indexMenu {
position: relative;
bottom: 3px;
width: 240px;
height: 32px;
float: left;
line-height: 30px;
border-top: 2px solid #FFFFFF;
text-align:center;
text-transform:uppercase;
text-shadow: 1px 1px 1px rgba(255, 255, 255, 1);
font-weight: 900;
color:#333333;
}
.sub_menu {
display: none;
position: absolute;
bottom: 33px;
width: 240px;
background-color:#DBF3FD;
opacity:0.8;
filter: alpha(opacity=80);
}
OK I've added a filter in the submenu to have a certain transparency
Gentleman,
Thanks for all of your responses! I'm sorry it took me so long to get back to this post.
This whole issue has revealed a few things I don't yet understand about the way HTML elements are rendered.
I was able to solve this problem by switching the main menu blocks to div elements instead of li elements.
This makes no sense to me in that both are rendered approximately the same way as far as I can tell from looking through the computed styles. But, for whatever reason, once the container is a div the contained divs rendered with their proper dimensions which allowed the rest of my code to work properly. I didn't even have to change the attached CSS!
As the main goal of this project was to finish and make the customer happy, I didn't experiment beyond this finding.
I welcome theories on why this would be.
Thanks again.
Clif
