Ok so let me explain. Lets say there is a small image and when you hover over it, there will be a new and much larger image (an enlarge version of the image). Thats easy, but wait! I want the larger image to be right on top of the smaller image and when you hover out of the smaller image, the div goes away. The problem is that when you display the larger image on top of the smaller image, the mouse is hovering over the larger image and not the smaller image. I want to make it so that the mouse stays hovering on the small image while having the larger image on top if it. And when you hover out of the smaller image the larger image disappears. The key is having the larger image on top of the smaller one (covering it up), but having the mouse under the larger image. Cant figure this out! Thanks guys
No, the mouse is always on top. But, you can accomplish the functionality you want - to hide the larger image when the mouse leaves the smaller image. There's more than one way to do it, for sure. Here's the approach I'd take.
HTML:
<div class="imgHover"></div> <!-- This div is the element that is hovered -->
<img class="large" src="largerImg.jpg" />
<img class="small" src="smallerImg.jpg" />
CSS:
.small, .imgHover
{
height: 55px; /* Set the div's size to match the smaller image */
width: 80px;
}
.imgHover, .large
{
position: absolute;
}
.large
{
display: none;
z-index: 2;
}
.imgHover:hover + .large /* this bit is the important part */
{
display: block;
}
.imgHover
{
z-index: 3;
}
If you want to do it with JavaScript instead of pure CSS, that's ok. Set it up with the same css, but use div.imgHover to attach your mouse events.
The solution would be to handle hover on the larger image but in the handler have the larger image go away when the pointer's x and y positions leave the boundaries of the smaller image.
Sounds like your problem is because with the .hover() because you have the new div opening over the old one it causes the .hover() to fire the mouseOut function. The best solution is to add to the .hover() so the mouseEnter also includes the larger image that "grows" out of the smaller image.
something like
$("#small_image, #large_image").hover(function (){...},function() {...});

My page has a 1000px container for the header(above the red box in below image) and the content(below the red box in the image attached). Those containers are fixed width. But I need to setup a image slider that will be displaying the images in full width.
I mean, I will be including a much wider image. Say, 1800x200 px. So, if the user's screen resolution(width) is less than or equal to 1000px, then the middle portion of the image would be displayed and the image slider should be 1000x200 px in size(resized). But if say the user's screen resolution is 1300(width), then the image slider should be resized displaying the center portion of the image and the slider container would be of size 1300x200 px in size!
Since there are lots of jQuery plugins already available, I thought of not to reinvent the wheel. So tried many jquery sliders. But none of them seems to be meeting my above needs. Or am I missing some settings in those sliders that I tried?
Any suggestions?
Maybe add an extra outer container? Then center the 1000px container within the outer one.
Then when you resize the window the image slider will respond to the outer container and the inner container stays centered.
outerContainer {
width: 100%;
.....
}
innerContainer {
width: 1000px;
margin: auto; /*or left:50% right:50%*/
}
you have to wrap all div in .wraaper div and define width 100%.
.wrapper{width:100%;}
and in inner div you have to define section using an
.inner(width: 1000px;)
where you need 100% slider dont use this .inner class.
this is help for you.
EDIT: Thanks for a lot of great examples on how to solve these. I cant decide between who to accept yet, but I will go though all examples and see which I like the most. Great feedback guys! =D
I normally do these kind of things in flash, but this time it has to be compatible with mac, iPads and all those units too.
So, what do I need help with?
I've got a picture, with some "hotspots" on. I want to be able to click any of those hotspots to show some information.
This should be fairly basic and easy to achieve, but since I've never done this in html before I have to ask you guys =)
So, what would be the best way to do this? It have to be compatible with any browser and device, and it doesnt need to be very advanced. If it's possible to add effects to the box (sliding out, fading in, or anything like that) then thats a nice bonus, but not something I need.
Any help would be great!
BREAKDOWN:
I have a background image with some "hotspots" (numbers 1 and 2 in my example). The users should be able to either hover the mouse over any of these or click it to get more information, as seen in picture #2
This is that happens when you hover/click any of these hotspots.
Text and image is displayed inside a nice little info box.
If the user clicks "more information" it will open up even further to display more information if available. Like in this img:
I don't think the Javascript approach is really necessary here. I created a little CSS-only mock-up for you on JSBin.
Basically the point is that you enclose the image in a relatively positioned div, then absolute position the hotspots inside the same div. Inside the hotspots divs you will have the more info elements, showing only on :hover of their parents.
This makes it simple, and far more accessible.
Update: cropping the image equally from both sides
If you want to keep the image centered and still not use any javascript, you could set the required image as a background-image of the container, and setting its background-position parameters to center center.
You would have to make sure that the width of this div is set to the width of your image, and the max-width to 100%, so that when the window gets resized below the image width it stays at the center.
Now, a problem that I encountered here is how to make the hotspots stay center relatively to the image. I solved it this way:
I created a wrapper div for the hotspots with these characteristics:
margin: 0 auto;
position: relative;
width: 0px;
This basically makes sure that the wrapper div finds the center of our image. Then, you would position the hotspots relatively to the top-center position of the image, instead of the top-left as a starting point.
Then you have what you are looking for.
Working demo
Here's another approach, and in my opinion far superior to using a map or excessive JS. Place <div> elements on top of the element with the background-image and have HTML and CSS do the heavy lifting for you.
See it on JSFiddle
HTML
The HTML should seem pretty each enough to understand, we create <div>s with the class hotspot and rely on certain things being present. Namely .text (to show digit), .hover-popup (to show on hover) and .click-popup (which is inside .hover-popup and is shown when clicked).
<div id="hotspot1" class="hotspot">
<div class="text">1</div>
<div class="hover-popup">
I was hovered!
<div class="click-popup">
I was clicked on!
</div>
</div>
</div>
<div id="hotspot2" class="hotspot">
<div class="text">2</div>
<div class="hover-popup">
I was hovered!
<div class="click-popup">
I was clicked on!
</div>
</div>
</div>
CSS
This is where most of the magic happens, see the comments for further explanation.
/* These two position each hotspot */
#hotspot1 {
left:15%; /* we could use px or position right or bottom also */
top:20%;
}
#hotspot2 {
left:35%;
top:25%;
}
/* General styles on the hotspot */
.hotspot {
border-radius:50%;
width:40px;
height:40px;
line-height:40px;
text-align:center;
background-color:#CCC;
position:absolute;
}
.hotspot .text {
width:40px;
height:40px;
}
/* Show the pointer on hover to signify a click event */
.hotspot .text:hover {
cursor:pointer;
}
/* hide them by default and bring them to the front */
.hover-popup,
.click-popup {
display:none;
z-index:1;
}
/* show when clicked */
.hotspot.clicked .click-popup {
display:block;
}
/* show and position when clicked */
.hotspot:hover .hover-popup {
display:block;
position:absolute;
left:100%;
top:0;
width:300px;
background-color:#BBB;
border:1px solid #000;
}
JavaScript (with jQuery)
Unfortunately you're going to have to use some JavaScript for the clicking part as CSS doesn't have a 'clicked' state (outside of hacks with checkboxes). I'm using jQuery because it's dead easy to do what I want.
$(document).ready(function () {
$('.hotspot').click(function () {
$(this).toggleClass('clicked');
});
});
Creating the arrow
Over at css-tricks you can find a tutorial for attaching an arrow to a element using the :before and/or :after pseudo-elements. You can even 'simulate' a border around them by placing the :after element on top of the :before. But yea, lots of resources on how to do this.
You should be able to use the onclick or OnMouseOver event in the map area (define the href as "").
An example using OnMouseOver is here: http://www.omegagrafix.com/mouseover/mousimap.html
Give a class for that image in html (Ex: imgclass). And in javascript(using jquery), build that hover box in html format and bind it to 'mouseover' event of that image.
For example:
function bindhtmltoimage() {
myimg = $('body').find('.imgclass');
divSlot.each(function (index) {
$(this).bind('mouseover', function () {
try {
//position the hover box on image. you can customize the y and x axis to place it left or right.
var x = $(this).offset().left;
var y = $(this).offset().top;
var position = $(window).height() - ($("#divHover").height() + y);
var widthposition = $(window).width() - ($("#divHover").width() + x);
if (position < 0 || widthposition < 0) {
if (position < 0) {
$("#divHover").css({
position: 'absolute',
left: x + 20,
top: y - $("#divHover").height() - 20
});
}
if (widthposition < 0) {
$("#divHover").css({
position: 'absolute',
left: x - $("#divHover").width(),
top: y + 20
});
}
}
//build your html string for that hover box and apply to it.
$('#divHover').html("your Html content for that box goes here");
$('#divHover').show();
//if you want the box dynamically generated. create the html content and append to the dom.
}
catch (e) {
alert(e)
}
});
});
}
it will work fine in desktop and mobile. if you face any problem in touch devices, bind the function to click event instead of 'mouseover'.
Also, for map approach, i strongly recommend SVG instead of images.
I have an image on a webpage. It's a pretty big image, however. It's 6144*768. In actuality, it is a series of 6 images mushed together.
I read that it's better practice to load this one image instead of loading 6 images. I've found this to be true as well, when I used tables and CSS.
However, when I set this image as the source of an image element and then set the size of the image element to 1024*768, the image is squished. Ack!
How can I get this image to be not-squished by using only Javascript? Also, how could I move the background of the image?
[example: Imagine a really long strip of paper. Then, place a small cut-out rectangle of paper over that somewhere on the strip of paper, so that you can only see the part of the strip that is inside the rectangle. This is what I want to do]
Place the image inside a container element, and set the overflow to hidden using CSS.
Leave the image as it is and it won't be squished
HTML
<div id="imgContainer">
<img src="myImage.jpg" alt="" width="6144" height="768" />
</div>
CSS
#imgContainer
{
height: 1024px;
width: 768px;
overflow: hidden;
}
Then to move the image use negative values for the CSS style margin-left.
#imgContainer img
{
margin-left: -1024px;
}
You can do this with jQuery as follows
$("#imgContainer img").css("margin-left", "-1024px")
What OP is looking for is CSS Sprites (also see A List Apart or Smashingmag).
Don't scale your image with CSS; instead, put it in a wrapper div and do something like this in your CSS:
#myImageWrapper {
height: 1024;
width: 768;
overflow: hidden;
}
I'm working on a web app where I have an image, and, for lack of a better word, a "view" of that image which is a box limiting what you can see to whatever part of the image is inside the box. The view can be adjusted by dragging the edges around, and the image is stays. However, I also want to be able to drag both the view and the image around together.
The best analogy I can think of is the Snipping Tool in Windows that you use to capture a portion of your screen.
I've tried a div with a background image, but that always resizes the image to fit the div. Right now I'm trying to have a div that contains an img, and setting the div to have overflow:hidden, but that makes the image stick to the upper left corner of the div.
Help? Thanks in advance!
Sounds like you want something that masks the image and only shows a segment.
Assuming a structure like.
<div class="img-mask">
<img>
</div>
You can set the styles of the mask to be overflow hidden with a width and a height (this creates the mask). Then position the image relatively, left and top till it's where you want it to be.
.img-mask {
overflow: hidden;
height: 200px;
width: 200px;
}
.img-mask img {
position: relative;
top: -25%;
left: -25%;
}
This should center the image to the mask.
I think there's a CSS property cut out for exactly this task: the clip attribute.
Here's the W3schools tutorial: http://www.w3schools.com/cssref/pr_pos_clip.asp. Click the Try it Yourself button to get a hands-on idea.
With this the CSS property applies only on the image and you do not need an additional masking div.
I need to slide a background when clicking the "next" arrow, and the "previous" arrow - right now the background is in the #container element - However, that doesnt work - I've tried putting the background on the ul#slider element - But that doesnt work either...
What i need is that the background will be slider as much as the liinside the slider...
Any suggestions on how to do that ?
You can see the project here: http://www.i-creative.dk/Slider/
thx
I've built something like what you're asking for, and it's a total pain.
The problem is, you're talking about having a different background image, the size of the page, for EVERY slide.
2 options are:
1: Have one BIG background image, with all the background aligned horizontally, and animate the css background-position when you change a div, to keep things matching. This ahs the advanatage that only one image needs to be downloaded, but it will be big.
Problems are: you see all the other images if you jump multiple steps at once;
it requires that you use a fixed width;
it's a pain if you want to change the background for just one slide;
Preload the background for the next slide on a div which is a sibling of container but has a higher z-index. Use jquery to slide this over the existing background, from the appropriate side.
The good thing about this method is that you can use css to make the background image always take up the full-width of the screen, or use a bigger imager and have it centred. See here: http://cksk.com for an example.
Long story short, you won't get this working with an off-the-shelf solution, you'll need to get your hands dirty.
Also, you'll need to spend a hell of a lot of time on optimisation.
Try this css...
#slider {
width: 472px; /* divided the width of the background image by 4 (# of panels) */
height: 570px;
list-style: none;
/* start background after the initial cloned panel: 472px to match panel width */
background: transparent url(../images/background.png) 472px 0 repeat-x;
}
/* This makes sure the last cloned panel background matches the first panel */
ul#slider li.clone {
background: transparent url(../images/background.png) 0 0 repeat-x !important;
}
/* Make the background visible */
div.anythingSlider .anythingWindow {
overflow: visible !important;
}
The only problem is that the width of the UL is limited, so when you get to the last panel, the background ends, but reappears once you hit the right arrow.
