Dynamically repeat/tile div and child(s)? - javascript

I've been doing some searching on here and Google and I can't seem to find an answer that quite fits what I'm trying to do. I have a single div with some text in it that does a fade effect by transitioning to a different background image on mouse hover. What I want to do is to tile/repeat that same div dynamically so it fills the entire body (or parent div). Kind of like using background-repeat:repeat but with a div instead of a background image. I like to see what kind of cool visual effects I can achieve with elements across the entire page fading in and out as the mouse moves over them.
Of course I could just copy and paste the same div in the code a bunch of times but there must be a better solution. I'm thinking javascript is needed, but the only things I've been able to find about cloning divs look to be a bit over my head and I'm wondering if there is a more simple solution.
The CSS and HTML that I'm using as an example is from menu links on a site I'm working on. It may not be the best example but I'm a bit new to CSS. Basically I want to tile the below div across an entire page.
Here is the css:
#fadediv {
background-image:url(images/buttonback.png);
transition: background-image 0.5s linear;
-moz-transition: background-image 0.5s linear;
-webkit-transition: background-image 0.5s linear;
}
#fadediv:hover {
background-image:url(images/buttonback2.jpg);
}
.fadedivtext {
display:block;
width:320px;
height:138px;
float:left;
font-size:30px;
color:#FFF;
text-align:center;
line-height:138px;
}
And the HTML snippet:
<div id="fadediv" class="fadedivtext">about me</div>
EDIT: Looks like there's a PHP example here that could work, in addition to the javascript example given below.

I think clone should work well for you -- it's not that complicated, especially when you're talking about a basic div. Just make sure to target classes instead of IDs (you're not supposed to have multiple elements with the same ID).
Here's a basic example using JQuery's clone:
var numberOfClones = 20;
var el = $("#fadediv");
for (i=0 ; i<numberOfClones ; i++) {
var newEl = el.clone();
$("#container").append(newEl);
}​

Edit
This is a comment left by aug:
Or if you want to for some reason give each clone a unique id you can access the attribute field and change the id to something else
newE1.attr("id", newId);

hide/unhide HTML portions by hovering?

more precisely, I've seen websites where there's a kind of header image, which loops through 3-4 different images, and each image is referenced by a dot, and you can pick the image you want by clicking the dot as well. I'm sure everyone has seen this somewhere.
as an example, go to http://www.tsunamitsolutions.com/
my question is, how do I make these dots appear/disappear when I hover on the image (like on the site I shared above) is it javascript or can this be accomplished just in the CSS with the "hover" style.
In other words, can hovering over one html portion/div/section make another div/section appear/disappear just by using CSS?
It can be done in the CSS.
Assuming the dots/arrows are child elements of banner container, you can do something like:
.bannerContainerClass .dotClass {
display: none;
}
.bannerContainerClass:hover .dotClass {
display: block;
}
You can also do it in jQuery if you need effects like fade:
$(".bannerContainerClass").hover(function() {
$(this).children(".dotClass").fadeIn(500);
}, function() {
$(this).children(".dotClass").fadeOut(500);
});
The jQuery method can be modified to work even if the dots aren't children of banner container.
You can accomplish it using Jquery and javascript. As in any website header images there is a tag for image one tag for collection of those points.
Suppose.
<div id="header_image">
..code for header image..
</div>
which is header tag. and there is a tag which cointains the points.
<div id="points_container">
..code for points...
</div>
Now in its javascript code if you want to disappear "points_container" tag when mouse is hovered over "header_image".and appears again when mouse is hovered out, you can write in its Javascript code.
$(document).ready(function(){
$("#header_image").hover(function(){
$("#points_container").hide();
},function(){
$("points_container").show();
});
});
You can use css on hover with either the visibility attribute or opacity attribute to hide an object, the full implementation of a gallery widget like this is somewhat more complicated though. CSS solution:
.dots:hover
{
opacity:0;
}
Makes anything with the dots class invisible on mouse over.
Or if you don't want it to take up any space when invisible:
.dots:hover
{
display:none;
}
Try this with simple CSS transitions, like this
HTML
<div id="parent"><br/><span class="bullets">* * * *</span></div>
CSS
.bullets{
opacity:1;
}
#parent:hover > .bullets{
opacity:0;
transition: opacity .2s ease-out;
-moz-transition: opacity .2s ease-out;
-webkit-transition: opacity .2s ease-out;
-o-transition: opacity .2s ease-out;
}

Hover over image, darken background only

I would like to be able to hover over an image and only the background itself to turn black (with opacity to control how much). I already have have an effect for the image itself when it's on hover, but I would like to add an effect where the background which is white to turn to a darker color. Being able to manipulate it later on with opacity and transition would be best, but I have not been able to find css3 or jquery code that works for this so far to get me to that point. Any help would be appreciated.
html
<div class="template_design2" style="margin-top:100px; margin-left:5px;"></div>
css
.template_design2 {
background-image:url(img/template_design2.jpg);
width:740px;
height:280px;
background-repeat:no-repeat;
float:left;
}
.template_design2:hover {
background-position:0 -280px;
}
You need to add a class to your <a>s that contain the background images, so you can target them.
You use .template_design:hover, so to target the first one (since it has no class, but you can use its ID to test it works quickly, then assign all <a>s inside .template_design a class so you can target them all at the same time):
.template_design:hover a#zapzonePoster { opacity: 0.5; }
Here's a fiddle showing how it works:
http://jsfiddle.net/v6aNY/
So once you know that's working, you could then assign a class so it would be more like:
.template_design:hover a.thumbnail { opacity: 0.5; }
... which will target all of them, so you only need one rule to govern it, instead of many.
Here's the same fiddle updated with a class of .thumbnail:

Animate opacity on image load

I have tried a bunch of different solutions to similar problems on here but none of them seem to be doing anything for me. See my jsFiddle to see an example of what I would like to happen: http://jsfiddle.net/Amp3rsand/HSNY5/6/
It animates how I would like but it relies on .delay when I would prefer it to fire as soon as the image is finished loading. The commented out sections in the js are the things that I have tried.
Could the problem be that the image is actually the background of a div rather than its own element? I tested making it its own <img> tag as well but it didn't seem to make a difference. I have the image as the background so that when I use media queries it is easy to swap in a different, smaller image for mobile users or small screens.
HTML:
<header></header>
<div id="image">
<div id="blah"></div>
</div>
The image I would like to fire after it finishes loading is the background of '#image'. Then I would like for it to animate to 'opacity:1;' while '#blah' and 'header' are animated into place.
Here is the jQuery I'm using right now but it is not correct:
$('#image').hide().delay(800).fadeTo(600, 1);
$('#blah').css("left", "-650px").delay(1400).animate({left:'30px'},400);
$('header').css("top", "-150px").delay(2000).animate({top:'-5px'},400);
On my website it is quite a large image so it takes about half a second to load but this code doesn't take into account caching or different network speeds.
What am I doing wrong or what should I do differently?
Thanks everyone
EDIT:
I gave the imagesLoaded plugin a go earlier and it seems to work on my website but I can't tell if it is actually doing what I want or just emulating my code from above.
$(document).ready(function() {
$('body').hide().fadeTo(500, 1)
});
imagesLoaded( document.querySelector('#homeimg'), function( instance ) {
$('article').hide().fadeTo(600, 1);
$('#caption').css("left", "-650px").delay(800).animate({left:'30px'},400);
$('header').css("top", "-150px").delay(1400).animate({top:'-5px'},400);
});
'#homeimg' being the div with the image as the background and 'article' being the container for '#homeimg' and '#caption'
I can only test with the website loaded locally at the moment so I can't simulate a slow connection. Does the code above do what I am looking for? Sorry if it should be obvious
Your image is loaded via a CSS background property, you will not be able to detect the loading of that. Why not use <img> tag for images?
If you use <img> you can read this question: Browser-independent way to detect when image has been loaded for a bullet-proof solution.
If you insist on using a background CSS property you will need to implement a way of sending your image as a data url encoded as base64 as described in this answer: https://stackoverflow.com/a/13989806/2788
Try animate
$('#image').animate({ opacity: '1'}, 600);
You can set the initial opacity to 0, and when the image onloaded, set the opacity to 1. With CSS you can make a transition between the two states:
<style>
.easeload{
opacity: 0;
-webkit-transition: all 2s ease;
-moz-transition: all 2s ease;
-ms-transition: all 2s ease;
-o-transition: all 2s ease;
}
</style>
<img class="easeload" onload="this.style.opacity=1" src="https://dummyimage.com/320x240">

Updating text of element makes it disappear

In Chrome 27 (Windows) when I update the text of a specific element, the text disappears completely until I make it "refresh" but changing the CSS of any element or window size or whatever.
Firefox is fine, haven't tried any other browser or OS (yet). I suspect its a Chrome-specific bug. I just want to make sure I'm not going insane.
I am using: CSS3 transforms in some places; web fonts (tested without them and it still happens); nested position: fixed and z-index
It's similar to this SO question however when I disable web fonts (and falled back to Arial then sans-serif) it still occurs. I suspect it has something to do with the layering I'm doing and CSS3 transforms.
The element updating is a DIV within this container:
NAV {width:100%;height:50px;position:fixed;top:0;left:0;z-index:110;padding:15px 0;text-shadow:1px 1px 2px #FFF;font-size:110%;font-weight:500;color:#565656}
Which is wrapped in a parent page:
#pages {width:100%;position:relative;overflow-x:hidden}
#pages .page {width:100%;height:100%;position:absolute;top:0;left:0;padding-top:50px;-webkit-transition:all 0.5s ease-in-out;-moz-transition:all 0.5s ease-in-out;-o-transition:all 0.5s ease-in-out;-ms-transition:all 0.5s ease-in-out;transition:all 0.5s ease-in-out}
I apply CSS3 transforms only when animating pages in/out, however the bug occurs after the transform is complete:
#pages .page.left {-ms-transform:translateX(-100%);-o-transform:translateX(-100%);-moz-transform:translateX(-100%);-webkit-transform:translateX(-100%);transform:translateX(-100%)}
#pages .page.right {-ms-transform:translateX(100%);-o-transform:translateX(100%);-moz-transform:translateX(100%);-webkit-transform:translateX(100%);transform:translateX(100%)}
The code that updates the text (trimmed down):
$('.page[data-page="Game"]').find('NAV .title').text('My text');
I don't have a demo to show you yet, sorry. If you need more code, please let me know in the comments (as I'm sure you would do anyway). I've left out the HTML because I believe it's irrelevant unless you really want to see it.

How can I affect Opacity of an image whilst hovering a div?

I'm so so close to acheiving what I want... but I'm wondering if I've hit the limit of what is possible with css.
If you navigate to http://host17.qnop.net/~gjcwebde/ecocamel/index.php?option=com_content&view=article&id=28&Itemid=49
We have a product slider. I'm trying to get it so that..
1) products start at 100% opacity on load.
2) hover over a product.. and the one you are hovering over stays at 100% opacity, the others all go to say 0.5 opacity (dim down).
I have ALMOST achieved this with css. Yo can see it working, except, when you hover over the description that pops up... the active image goes back to 0.5 opacity. Is it possible to control the opacity of this image, whilst hovering over the popup description? I really really hope so! Failing that... how might I acheive this with js? Looked at some on here, but none really apply to my situation. Hope I've given enough information for you to understand. Cheers!
#containingDiv:hover img { } will affect the img when any of the containing div is hovered over so I would use that if I were you, Ryan's solution will only affect the img if you are hovering over it
I picked up your html and put it in a fiddle. Take a look http://jsfiddle.net/hMW8N/
Anyway, this is all you basically need. I'm over specifying with these selectors, but I'm doing it so you can better understand.
#slider-list-stick-1:hover .slide-index{
opacity: 0.5;
filter:alpha(opacity=50); //ie
}
#slider-list-stick-1 .slide-index:hover {
opacity: 1;
filter:alpha(opacity=100); //ie
}
This should work for the opacity on the images when the user is not hovering.
divName img {
opacity:0.3;
filter:alpha(opacity=30);(IE)
}
And then when they hover (this should include your product info styling to as you have that displayed when hovering.)
diveName img:hover{
opacity:1.0;
filter:alpha(opacity=100);(IE)
}
Also throw in an active class on start so that at least one product is being shown when the page loads
For example:
divName img .activeLoad{
opacity:1.0;
filter:alpha(opacity=100);(IE)
}
Add to your styles this declaration
.slide-index:hover img{
opacity: 1;
}
As other divs are also in the slide-index container - the hover effect will still be applied.
