Fix position: absolute element in a overflow: scroll element when scrolling - scroll

I want to accomplish a preview of an image gallery that is wider than the screen, using overflow: scroll (or auto).
To the right, a shadow that overlaps the last visible image should indicate that more images are visible to the right.
Here is a Fiddle: http://jsfiddle.net/SBdLg/
First, I thought: Easy, give that image gallery a box-shadow: inset. But that will be shown behind the images.
Now, with an overlapping div that has position: absolute, I reach the desired effect BUT the box-shadow also moves when scrolling to the right.
IMHO, this problem would also occur when using an image containing the shadow instead of the div on top.
Is the desired effect possible by CSS at all?

Removing position: relative from the outer DIV and positioning the shadow precisely where you need it (this is the ugly bit) will help you achieve this.

How to prevent a list from scrolling horizontally

I have created a list using a block element contained in a view. When the block contains enough items, I am able to scroll vertically as intended.
The problem here is that, even if the block does not overflow vertically or horizontally, I am also able to scroll horizontally. This is illustrated in the following pictures:
Normal operation:
Scrolled horizontally:
Here is the ACSS for the containing view:
position: absolute;
top: 378rpx;
width: 750rpx;
Is there any way to constrict the block from scrolling horizontally?
So it turns out that a higher-order view accidentally had a width that was more than 750rpx and this allowed scrolling to the side.
Fixing that made that the list stays in the same place horizontally.

Move elements toward each other

I want to create a click event that will have two photos on opposite corners of the screen move towards each other, once they collide, they move back in the direction they came from.
I am having trouble placing an image on the top right corner. I tried using "float: right" but when I tried that, my function does not work.
To place the images on the top right corner you should use absolute positioning:
.class {
position: absolute;
right: 0;
}
Also do you really need javascript to animate this?
It would be better and more performatic to do it with some CSS. Checkout this fiddle I made: https://jsfiddle.net/jv5et9L0/
In the fiddle I use absolute positioning to put the elements where I want, and then, through Javascript, I add apply the transform() property on my CSS. The animation occurs because I have set the transition property on the .item class.

Fixed Positioning not working in Safari 7

I'm having a problem on a website with Safari 7 (on OSX).
The website address is:
<Edit: Address not valid anymore. Sorry.>
If you click on vertical newsletter button, on the right edge of the content box, an overlay will pop-up.
This overlay looks good on most browser, but there is a problem with safari.
The overlay content is an absolutely positioned box of fixed width. It contains a div with the class "bg", which is a div with CSS position set to fixed and CSS top, right, bottom left set to 0.
The desired (and normally obtained) effect, is that this bg box sizes up to the width and height of the viewport. In safari, it just behaves as if it had it's position set to "absolute" - it just sizes up to the width and height of the container div.
Is this a known issue with Safari? Is there a bug filed? An update?
I could probably fix that by rewriting small parts of the HTML, CSS and JavaScript (if someone has an easier solution, you're welcome to share it!) but I'd like to understand what's happening at first.
I'm not sure what's going on with that positioning thing, but here was my approach to get the same result across the browsers:
#overlays .overlay { /* line 1081 */
...
width: 100%;
height:100%;
...
}
#overlays .overlay .content.text { /* line 1185 */
...
margin:0 auto;
...
}
You could use Z-index but Z-index is not reliable with position:fixed, as shown in this fiddle: http://jsfiddle.net/mZMkE/2/ use translateZ transformation instead.
transform:translateZ(1px);
on your page elements.
EDIT: In your code, Add this css:
.bla, .projects, .contact {
-webkit-transform:translateZ(1px);
-moz-transform:translateZ(1px);
-o-transform:translateZ(1px);
transform:translateZ(1px);
}
and then remove z-index refs from those elements and .intro.
Also You can try in other browsers as well

How to add an image inside a container without the container moving out of proportion?

I created a shape (a rectangle to be exact) and in this shape I wish to have an image overlapping its actual size (e.g the rectangle would be 400px by 400px and the image would be 600px by 600px).
Are there any ways of doing this? Here's a mockup of what I'm describing:
EDIT: To achieve this, simply use
z-index: 1;
position: absolute;
Thanks user acarlon.
I am not 100% sure what you are after, but it sounds like you want an image cropped to a container div.
What you want is overflow: hidden on the container div. See here for details.
You can also use clip. See here.
Update
Actually, it seems like you want one image to overlap another. In which case you want to use absolute positioning and z-index. See here.

CSS max-height and overflow auto always displays vertical scroll

I have a div class set up with the following CSS style:
div.multiple_choice{
border: 1px solid black;
max-width: 300px;
max-height: 200px;
overflow: auto;
}
The problem is, when the text inside doesn't force the DIV to reach the maximum height of 200px, the vertical scroll bar still shows up. I can click on the up and down arrows but it only moves the contents up and down by about a pixel or two.
This is occuring in Google Chrome (version 18.0) and Iceweasel 11.
As it turns out, another CSS style was causing the issue:
body{
line-height: 1;
}
Anyone interested in learning about how and why this would cause an issue, can read about the line-height property here
I was having an issue with this, and I found that having position: relative on the child elements was causing the problem. Obviously this can't be the solution for everyone, especially if position: absolute is being used, but for me it worked.
Just to put in evidence the #Kuba Orlik's solution (he posted as comment on the accepted answer) that's the only one that worked for me.
Add this on inside elements:
line-height: normal;
Note: Explicitly normal not 1 because it's different
I have encounter this problem.But I solved this use the following css style:
div.yourcontainer{overflow-y:auto;}
If the container was higher than max-height,the vertical scrollbar will show.
I had this problem when trying to wrap a list (flex column) of react components in a div, I resolved it by changing margin of elements within each list item to be 0.
The approach to troubleshoot this for me was to inspect the list items (perhaps each <li> in OP) and see what styles were making the div think each list item was larger than what was visible to the human eye.
Here is an example of inspecting a rogue margin on an icon within a list item in my project:
Solution is to set the style of that icon to have a vertical margin of 0, though in my application I just made all the margin 0 and added some padding-right.
I also had this problem using Bootstrap and nav. It occurred because bootstrap definds the li in nav-tabs as: .nav-tabs > li { margin-bottom:-1px; }. To counteract this, you must also do:
.nav-tabs > li:last-child {
margin-bottom:0;
}
Without setting the last-child, the following example would always show scroll, no matter how much content is in the list:
<ul class="navs nav-tabs nav-stacked" style="max-height:80px;overflow:auto;">
<li></li>
...
</ul>
I came across this bug earlier today. In my case a list of child elements had display: inline-block instead of display: block. Switching to display: block for my list of child elements in the truncated div fixed the issue for me.
In my case, the problem was with the font. We use font-family: Galano Grotesque. Apparently, this font is rendered higher than the computed height.
<div>
<p>some text</p>
</div>
So even without max-height, when the inner p and the outer div were both computed as 20px height, there was still a scroll bar (with overflow: auto) because the font was about 1px higher than expected.
So the solution can be any one of:
Use a different font.
Add padding to the outer div. This way it will be large enough to cover the extra pixel that comes from the font. In my case, adding one pixel of padding to the bottom and one to the top solved the problem.
Set line-height to a bit larger value (in my case, from 1.25 to 1.4), so it won't interfere with the font.
Set line-height to normal because then the actual value will be influenced by the font. However, according to Mozilla, this is not the preferred way.
The reason for the vertical scroll is obvious: the scrolled content is higher than scrolling area. But when you observe their heights, they are equal!
The causes are multiple but all come down to a common one: an element inside the scrolled content overflows it and makes the result taller.
How to fix this?
find the guilty element by looking near the bottom edge of the scrolled element (or to the right if you're scrolling horizontally), because they are the most likely to overflow. You should observe a height larger that their parent's.
see what makes them overflow, be larger than their container. As other answers suggest, it can be line-height, some margin, etc. Change those properties to make them fit, or as an alternative, set overflow-y: hidden to their immediate parent.
