I have an image that only appears when icon located within a pagegridview is selected. What should happen is that the overlay shows, with the full sized image on top of it. What really happens is that the overlay overlays my full sized image and off centers it. My code stands as followed:
CSS
#overlay{
position: fixed;
width: 100%;
height: 100%;
top: 0px;
left: 0px;
background-color: #000;
opacity: 0.7;
filter: alpha(opacity = 70) !important;
display: none;
z-index: 100;
}
.fullView{
position: absolute;
}
Javascript
Works fine to display, can't test the hiding due to overlay being on top.
$('.preview').click(function(){
$("#<%=imgFull.ClientID%>").attr("src", $(this).attr('fullImg'));
$("#overlay").show();
$("#overlayContent").show();
});
$("#<%=imgFull.ClientID%>").click(function(){
$("#<%=imgFull.ClientID%>").attr("src", "");
$("#overlay").hide();
$("#overlayContent").hide();
});
Overlay/Full Image Divs
Located right below an ASP Panel and a PageGridView
<!-- Divs for displaying the full sized image. Initially hidden. Hides again when clicked -->
<div id="overlay"></div>
<div id="overlayContent" >
<asp:Image runat="server" ID="imgFull" Width="400" ImageUrl="" CssClass="fullView"/>
</div>
I could have sworn for the most part position:absolute css would solve the main portion, but the time crunch is on and I'm trying to do this with the flu. Any help is appreciated.
The answer was staring me in the face and I just didn't quite realize it. The #overlay# CSS was fine, however, I needed to additionally change the.fullViewtofixed` as well. Once this was done, the image hovered perfectly on top of the overlay, and I was able to utilize some CSS changes in the javascript to accurately center the image.

I have a site where people can embed instagram videos. I have these show up as thumbnails, and I would like to have an overlay popup (containing the full size video) when they click on the thumbnail. Unfortunately, instagram's embed code comes with built in links and when clicked the video simply plays at the small size.
So my question is: How do I create an invisible overlaying region+link that will ignore the links of the underlying content? (I have the popups coded and working properly, just need to figure out how to disable the links)
Thanks!
You can put a transparent div on top of the links you want to disable and give it a higher z-index.
#links {
position: absolute;
z-index: 999; /* simulating that the target has a manually given z-index*/
}
#maskDiv{
background: rgba(255,255,255,0.6); /* keeping it partially visible to demontrate it's there*/
width: 200px;
height: 42px;
position: absolute;
top: 40px;
z-index:1000; /* needs to be higher than the target div */
}
<div id="links">
A functional link<br />
Another functional link<br />
A link masked by a div<br />
Another<br />
Last one is functional<br />
</div>
<div id="maskDiv"></div>
I´ve been trying (and searching) since days, but didn´t got my idea work...
I use the featherlight lightbox to display HTML content (text with some images). Because of some pics are very small, i´d like to have an image-zoom on them.
Example of the zoom here: jquery.elevatezoom.js #6:inner-zoom
The elevatezoom.js works well outside the lightbox, but unfortunately not inside. Did/does anyone get this working together? Or do I need another javascript(?) I tried several.. Thanks for help!
The problem seems to be in the way the ElevateZoom plugin is calculating the position and dimensions of the image.
If you do try to put a picture inside the featherlight hidden div, you'll see that ElevateZoom does create a zoomContainer and everything is working, except this is its generated css:
left: 0px;
top: 0px;
height: 0px;
width: 0px;
This seems to happen because when you call $('#image_element').offset() it returns {top:0,left:0} I assume because when it's inside the featherlight container, its position is fixed.
I think the easiest way to fix this, if you haven't already found another image zooming library, is to just make this effect yourself. You would simple have two divs in the featherlight container, one hidden containing the larger picture, and one smaller containing the normal picture. When the mouse enters the picture, you hide the small and show the big. That would be the first step.
The second step is making it scroll. The way elevateZoom handles this is by setting the background-image to the large image, and moving it around using the background-position attribute. Here's what the elevateZoom generates as an example:
<div style="z-index: 999; overflow: hidden; margin-left: 0px; margin-top: 0px; width: 411px; height: 274px; float: left; cursor: crosshair; position: absolute; top: 0px; left: 0px; display: block; opacity: 0; background-image: url("images/large/image1.jpg"); background-position: -152.651px -545.577px; background-repeat: no-repeat;" class="zoomWindow"> </div>
Notice the background-image and background-repeat. You can move that around with Javascript as the cursor moves relative to where the image is positioned.
I hope this helps!
I have an image inside my page. After some javascript trigger event I want a cross appear on the image. Image will still be visible but cross will be on top.
What is the proper alternatives for this?
(I have similar question here that used HTML5 canvas)
I would create a wrapper for the both the image and the cross, and have them absolutely positioned within the wrapper. The wrapper itself would be fluid within the DOM, but the image and cross would be absolutely positioned so that the cross appears on top of the image. This can be done by setting the wrapper's position property to relative and using absolute positioning on its children.
As for the cross, I would use an image. This way you can set height and width to 100%, so that it will stretch with the wrapper. To control the sizing you would set width/height on the wrapper element, not the images themselves.
HTML
<div class="wrapper">
<img class="img" src="actual-image.jpg" />
<img class="cross-img" src="cross-image.jpg" />
</div>
CSS
.wrapper {
position:relative;
width: 150px;
height: 150px;
}
.img, .cross-img {
position: absolute;
top: 0px;
left: 0px;
width: 100%;
height: 100%;
}
.cross-img {
opacity: 0.5;
}
It's then trivial to show or hide the cross. Here's a jquery snippet:
$('.cross-img').hide();
Here is a jsfiddle demonstrating this: http://jsfiddle.net/J69qR/
I'm developing a jQuery Backbone.js web app.
I have a table with table entries. The table has a white background.
If the user selects a table entry, a modal popup is shown. To show the user that the popup is now in modal mode, I used to have the jQuery UI diagonal stripes (ui-widget-overlay).
But I changed to an alternative. Those stripes were too "striking", "obtrusive" for me. I now change the opacity of the table to 0.5. I like this more.
The problem now is that I have popups in the popup window. And if I also change the opacity of the first popup to show the user that only the second popup is working now, the table shines through the first popup.
Is there any possibility, any alternative way to have a popup window (a div) "dim", "grey out" to half of its appearance without getting transparent?
I would add another div on top of the div that has the same dimensions but has grey background color with opacity 0.75. This should work pretty fine.
CSS
.inner {
position: absolute;
}
.fade {
background: grey;
opacity: 0.75;
}
HTML
<div class="outer">
<div class="inner">content</div>
<div class="inner fade"></div>
</div>
This way you are pretty safe when it comes to cross-browser references. Also you can control the fade by adding an "id" attribute to the fade class and make it go away. This way, you can also make div inactive, as they div inner fade is on top of it.
Try with hsla (look here).
<style>
#el1 {
background: red;
width: 700px;
height: 700px;
}
#el2 {
background-color: hsla(190, 30%, 94%, 0.6);
width: 500px;
height: 500px;
}
#el3 {
background: green;
width: 300px;
height: 300px;
}
</style>
<div id="el1">
<div id="el2">
<div id="el3">
</div>
</div>
</div>
In my code, el1 is the holder and not transparent at all. Then, el2 as first child uses hsla for transparency. The contained el3 is not transparent again and this works.
You could lay a glass pane on top of your page and set the z-index appropriately so that your 2nd popup lies on top of it and everything else is hidden under it:
#pane {
position: fixed;
width: 100%;
height: 100%;
margin: 0;
padding: 0;
top: 0;
left: 0;
opacity:0.5;
z-index: 999;
}
Assure that your 2nd popup has a z-index higher than the pane and you're fine.
I just stumbled across this guys site: http://mantia.me/
He has an awesome logo that reacts to the content the site is currently showing, if you wait on his homepage the logo changes with the slide show of images. I was wondering if anyone knows how to replicate the effect. I'm guessing it's a transparent png with a rotating master background then the site is layered on top, but I'm probably wrong.
Any guesses on how to make something similiar?
Images:
It's really simple what he has. Like you mention it's a transparent PNG that matches the given background ( in this case white ) and places it on top of it with z-index. The rest is just jQuery with fadeIn and fadeOut images.
You can view the png on top of the image transitions.
So basically you just need a div with position:relative set the width the height of it; then add another div inside it which has the jQuery Slideshow (check this out: http://medienfreunde.com/lab/innerfade/), set it a z-index:0 Then add another div (which will go on top of the slider) and add it a background with z-index to something higher than 0 and you're good to go.
Here is how he does it:
HTML
<div id="content">
<div id="feature"></div>
<div id="navigation"></div>
</div>
CSS
#content {
position: relative;
width: 800px;
margin: 64px auto;
font: normal 13px/16px "myriad-pro-1","myriad-pro-2", sans-serif;
color: #404040;
}
#navigation{
position: absolute;
z-index: 1000;
top: 0;
left: 0;
width: 800px;
height: 46px;
background: transparent
url(http://mantia.me/wp- content/themes/minimalouie/img/nav.png)
no-repeat top left;
}
#feature {
width: 800px;
height: 466px;
overflow: hidden;
background-color: aqua;
}
And then he just adds an img element to #feature.
<div id="feature">
<img src="http://mantia.me/images/supermariobros_large.jpg"
alt="Super Mario Bros.">
</div>
