CSS images placement in table with absolute position - javascript

I am trying to cycle through two sets of images using some Javascript. In order for each image to replace the old one as it cycles, I need to use css and set the position to absolute.
I'd like to align the image sets in a html table. If I don't specify positions within the css, the two image sets are on top of each other. If I do, they ignore the table, which I think is caused by the absolute positioning.
Rather than display a lot of code here, I will share a JSFiddle: http://jsfiddle.net/n342aadc/3/

Add:
td {
position: relative;
width: 50px;
}
.container img.
.container1 img {
position: absolute;
}
fiddle
I think you need to specify a width for td otherwise it seems to collapse.

Change element css styling with js or jquery on the fly

I want to be able to change my navbar position on the fly adjusting remaining content accordingly.
So, I have a functiona website. There is a menu navbar on top by default. What I did is added an 'edit' button to that menu so that when you click it, you get a list of 4 checkboxes with the ability to choose if you want that menu positioned on top (default), left, right or bottom with the other content moving accordingly (e.g menu on the left, content goes slightly right, etc). So basically, I have something like this:
// css for menu positioning to the left
.navbar-left {
width: 25%;
height: auto;
}
.content-right {
position: relative;
left: 200px;
}
// css for menu positioning to the bottom
.navbar-bottom {
position: relative;
bottom: 0;
left: 0;
height: 200px;
}
.content-up {
position: relative;
bottom: 200px;
}
And in JS I do something like this
if($("#left"):checked){
$("#menu-bar").addClass("navbar-left");
$("#content").addClass("content-right");
} else if ($("#bottom"):checked){
$("#menu-bar").addClass("navbar-bottom");
$("#content").addClass("content-up");
}
Now, I have much more styling than this, but it is irrelevant to the issue at hand. The problem is when I choose 'left' it styles properly but when I change it to 'bottom' after that it still uses the styles from 'left' positioning and adds the new ones to it.
Right now I solved the issue by removing the previous classes with .removeClass() method, like that:
if($("#left"):checked){
$("#menu-bar").removeClass("navbar-bottom navbar-right").addClass("navbar-left");
$("#content").removeClass("content-up content-down").addClass("content-right");
} else if ($("#bottom"):checked){
$("#menu-bar").removeClass("navbar-right").addClass("navbar-bottom");
$("#content").removeClass("content-down").addClass("content-up");
}
Basically, right now I have about a hundred lines of just adding classes of the chosen positioning while removing all the classes of 3 other choices that I added each time.
So, finally the question: Is there any other way to strip all the classes that were used before (just set everything to initial values like when the page was loaded) instead of deleting all these classes by hand?
I haven't ever tried resetting the classes to their initial state, but you can certainly clear them all off of a single element in one line of code:
To replace all existing classes with another class, we can use .attr( "class", "newClass" ) instead.
source: https://api.jquery.com/removeclass/
You could probably combine that with the .toggleClass or another method.
If I had to sit down and do it right now, based on my understanding of your question I'd just hide the original elements and add new elements with the classes that you'd like, then to revert delete the new elements and restore the original one.

Bootstrap / Css - 2 DIV same height

I've got HTML+CSS code. I need 1st div (row-1, white colored) to take first half of the container height, and 2nd div (row-2, orange-colored) to take the second part.
Here is my html:
http://pastebin.com/ipiEKHBZ
and my css:
http://pastebin.com/jtxw695F
Revised answer: After realising the default approach did not work with your HTML, this should work. You have classes .content-row-1 and 2 respectively. You can use those to tell the corresponding rows to always use a certain portion of the height. For this to work you also need to manually fix the positioning. (Someone correct me if this can be done more elegantly) For example those classes could look something like:
.content-row-1 {
background: #eee;
position: absolute;
top: 10%;
display: block;
height: 40%;
width: 100%;
}
I noticed that your footer already takes 10% of the height and and assumed you did not want any overlap or gaps. For that to work you should also give your header a percentage for height (10% in my example to keep things simple).

Filmstrip Style Image Gallery

I am trying to figure out how to create an image gallery like the one illustrated below so I can place it onto my website. I am wondering if anyone can point me in the right direction for a tutorial? I have found a lot of nice galleries that will display my images, but none of them displays the images like in the filmstrip style I am after.
Requirements of gallery:
When clicking on the arrows, the gallery strip will either shift
left/right by one picture
Hovering over the image will darken the image, and display some
caption about the image
I just answered a question where someone was using carouFredSel. This jQuery plugin looks like it would work pretty well, though I do not think it has the built-in hover effect. To be honest though, that is the easier part.
The trick is to make the width slightly larger than the images to show, which leads to the partial images on each side.
Here is a jsfiddle to illustrate.
UPDATE:
The OP asked if the page nav links could be repositioned. I modified the jsfiddle to work this way. The additions were as follows:
.list_carousel {
position: relative;
}
#prev2 {
position: absolute;
top: 35px;
left: 0;
}
#next2 {
position: absolute;
top: 35px;
right: 0;
}
If you have a relatively positioned container element, you can absolutely position child elements. I added relative positioning to the list_carousel container, then I could absolutely position the nav arrows within the container. Change the top value to position vertically, and left/right to position horizontally.
I also removed the pager all together, as it was not a requirement based on the original example. If you change the page arrows to images it is pretty much what you want.
MORE UPDATES
I decided to take it one step further and make the hover effect work more like the example. See the new jsfiddle. The changes are:
Added span wrappers around all text within list items
Added $(".list_carousel li span").hide(); to hide all the spans
Modified hover event to toggle spans
I also added some CSS to position the span text:
.list_carousel li {
position: relative;
}
.list_carousel li span {
position: absolute;
bottom: 0;
display: block;
text-align: center;
width: 100%;
}
FINAL UPDATE (I PROMISE!)
I decided to go all in and add the transparency layer too: jsfiddle
Hover modifications:
$(this).prepend($("<div class='hover-transparency'></div>")); and $(this).find("div:first").remove(); to add/remove transparency layer on hover in/out.
CSS modifications:
.hover-transparency {
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
background-color: rgba(0, 0, 0, 0.60);
}
These style the transparency layer. Change to suit your taste.
Something like jCarousel should do the trick. Once you have the carousel functionality in place, you can add in the hover affect via CSS and a span that contains the caption.
I was just looking at ContentFlow Plugin which is JavaScript based.
They include a separate library of additional plugin you can use that takes care of your Slideshow requirements, in particularity this one HERE. When you use the mousewheel over the 3 images, it scrolls by 1. That said, you can mod the plugin to do the same when the arrow buttons are clicked.
Sample plugin markup looks like:
{
shownItems: 3, //number of visible items
showCaption: true // show item caption
width: 100, // relative item width
height: 100, // relative item height
space: 0.4 // relative item spacing
}
To address that the captions should be visible only on mouse hover, I would set showCaption to always be true along with using a jQuery .hover(); Event Listener that will use .show(); and .hide(); on the caption Class Name .caption when required. Also, using jQuery to set the opacity can be done within the .hover(); event too.
The latest version of ContentFlow v1.0.2 supports multiple instances on the same webpage if that's ever required.

Thumbnails from JS Gallery Placed in Footer

I am trying to add the thumbnails section of the js gallery in the footer of a web page. I've never broken up a gallery before and figured it's the only way to achieve this look
http://img69.imageshack.us/img69/5923/bsade.jpg
The link for what I have now is this: http://www.marisaraskin.com/two.html.
(The borders are just guides for me while I'm still working on it)
The CSS code for the thumbnails container is:
.galleria-thumbnails-container {
height: 100px;<br>
bottom: 0;<br>
position: absolute;<br>
left: 10px;<br>
right: 10px;<br>
z-index: 1;<br>
border:1px solid yellow;<br>
}
I'm not sure what my other options are for this. I was maybe thinking overlapping the content container over the footer with z-index. Though I'm iffy about that especially because everyone's screen resolution is different. I can post more code per request. I am not sure what else you need to see as of now.
In case you need to know I'm using a gallery js called "Galleria" (classic).
If I were you I'd modify the js script so that you can populate blocks that are not contiguous in the actual HTML code, but here's a rough approach to doing it all through css:
remove position:relative from #container
remove position:relative from .galleria-container
add position:absolute to .galleria-stage and remove left and right
positioning. Also, add top:90px (or something close to that) and
give it a width: width:920px.
change .galleria-thumbnails-container to use absolute positioning and
use the bottom:___ property to set it where you belong.
Basically what you're doing here is removing all the relatively positioning in the parent elements of the gallery so that the gallery segments all all being positioned with respect to the page rather than any of their parent elements. Once this is done, you can just modify the absolute positioning and width of the stage block and the thumbnail block so that they sit where you want them.

CSS Place one div directly over another

I have a div which has some stuff in it, and the user has the option of clicking an 'x' to say "This is not applicable to me", for example.
Rather than delete the div, I want to play a translucent div on top of it.
I started off with some complicated javascript to determine the size and location of my div in question, and create a new one on top of it. The script was giving a size and location which looked approximately right to my eye, but the overlap div was being put in the wrong spot.
Then I realised that there is (probably) a much simpler way to do this.
I put a div with class "blackout" inside the div I want to black out. The blackout css class has a visibility set to hidden, so javascript will set that to visible when needed.
The issue I'm having is that even with this method, I can't seem to get it to precisely fill the rectangle the parent div has.
I had
.blackout
{
position: absolute;
left: 0px;
right: 0px;
top: 0px;
bottom: 0px;
background-color: black;
opacity: 0.5;
filter: alpha(opacity = 50);
}
This filled up the whole screen rather than just the parent div.
What do I need to change to make it fill the parent div only?

What do I need to change to make it fill the parent div only?
You need to add position: relative to the parent div.
That will set the parent div as the "containing block" for .blackout:
If the value of the position property is absolute, the containing
block is the nearest positioned ancestor—in other words, the nearest
ancestor whose position property has one of the values absolute,
fixed, or relative.
Read more here: http://reference.sitepoint.com/css/containingblock
Using "position:absolute" positions it in relation to the next "position:relative" div. If there isn't one set then it will use the body.
You need to make the parent div CSS contain "position:relative"
On the parent div's CSS:
overflow: hidden;
should work
Add position: relative to the parent div, overflow: hidden will only hide the outside of your parent's div
Change position: absolute; to position: relative;
Set the child <div> width and height to be 100% and remove useless markup.
