I am using positioning(fixed/absolute)due to having scroll when content overflows, but the problem is if I have to change dimension of other parts, I must change position of the scroll-able container.
As far as I know to have a box scroll-able while overflowing situation, dimension of the box must be set!
Here is my css for the container:
.scrollable-box {
position: absolute;
top: 152px;
right: 0;
left: 15px;
bottom: 0;
overflow-y: auto;
}
Changing the position of a div dynamically does not affect its scrollability.Its not mandatory to position a scrollable div .
.list {
overflow-y: auto;
margin-right: 2px;
}
https://jsfiddle.net/526ctwew/
fiddle has two divs placed inline with no positioning done. Even if the scrollable div moves to next line(on resizing the screen) scrolling is not affected.
Hope this helps .

I am trying to build a layout where I have two divs in the background that span 100% of the page and then a full height wrapper div of a smaller size for content that sits centered on the page. The issue I am having is while I can get the wrapper to sit correctly on top of the top div; I cannot get it to behave correctly on the bottom div. Here is an example:
html,
body {
height: 100%;
margin: 0 !important;
padding: 0 !important;
}
.index-banner {
background: #265f7a;
height: 60%;
width: 100%;
}
.wrapper {
background: #444;
height: 200%;
margin: 0 auto;
position: relative;
top: -60%;
left: 0;
right: 0;
width: 50%;
}
.footer-bg {
background: #888;
height: 250px;
position: relative;
top: -85%;
left: 0;
right: 0;
width: 100%;
z-index: -1;
}
<body>
<div class="index-banner"></div>
<div class="wrapper"></div>
<div class="footer-bg"></div>
</body>
Now the issue with the above code is by using a negative positioning, then I leave a massive gap at the bottom of the page. However I have also tried:
Using an absolute positioning on the wrapper div. Works perfect in keeping the page the correct size however then the bottom div floats to the bottom of the viewport
Using a faux method of making the bottom div look like a full width div by using a background image on body; unfortunately this just sticks it to the bottom of the viewport instead of the bottom of the page due to no content being between both background divs.
Now I have thought about keeping the wrapper occurring naturally between both of the background divs so they do not overlap at all and then put divs inside of those background divs lined up with the wrapper however that becomes a bit of a nightmare that I want to avoid because then I have to struggle to try and align the content that overlaps them as each of those "section divs" would have to be split into two (imagine trying to make a paragraph look like one because it is spread between two divs).
So my question is - am I going about this the wrong way and overlooking something that I could be doing differently to make this work?
I am trying to do a footer that will stick to the bottom of the page instead I am getting it stuck to bottom position for the original window. When I scroll I end up having the footer stick in the middle of the page.
I am not trying to have it fixed and be sticky to the page.
When I do not have enough content to scroll all is well. (at least it looks that way)
Corresponding HTML:
<footer class="footer_div">
<div class="container">
<p>Sam Sedighian - No rights reseved!</p>
</div>
</footer>
Corresponding CSS:
.footer_div {
background-image: url("../imgs/dark_dotted2.png");
color: #818787;
position: absolute;
bottom: 0px;
left: 0px;
width: 100%;
height: 40px;
padding-top: 10px;
text-align: center;
}
It needs to be at the bottom of the page without being sticky (fixed) and only visible when scrolled to the bottom of the page. So it should work for both these examples: sedighian.github.io/blog/absolute_not_working.html and sedighian.github.io/blog/absolute_not_working2.html
This is an extremely subtle bug. Read the position: absolute documentation carefully:
Do not leave space for the element. Instead, position it at a specified position relative to its closest positioned ancestor or to the containing block.
footer does not have any positioned ancestors. Note that in the Bootstrap example, they explicitly declare position: relative on html.
In addition, you'll want to add a padding-bottom equivalent to the height of your footer so space is reserved for it.
Try:
html {
min-height: 100%;
position: relative;
}
body {
padding-bottom: 40px;
}
I'm essentially displaying a banner image on a page. At the base of that image is an overlay (the abs. pos. div) with a semi-transparent background image to make a "see through" effect. Everything is positioned properly and working fine except the overlay at a width of 100% expands outside of my container div. I've tried setting the overflow to hidden of the container div but that does not seem to work. My parent container has a position relative as well. This is responsive so the overlay with need to shrink and expand to the image width. Here's my code:
.hero-img-wrap {
position: relative;
margin-top: 35px;
padding-left: 15px;
padding-right: 15px;
}
.hero-img-wrap img {
width: 100%;
height: auto;
}
.hero-img-wrap .trans-overlay {
position: absolute;
bottom: 0;
z-index: 9;
height: 19px;
background-image: url('../images/semi_transparent_white.png');
width: 100%;
}
<div class="hero-img-wrap">
<img src="images/banner_image.jpg" alt="">
<div class="trans-overlay"></div>
</div>
I could pull this off with JQuery but I'd like to avoid that. For what it might be worth - this code is within a Bootstrap 3 column.
Since you've defined the height, why not a negative value
position: relative;
top: -19px;
Just a thought, heres a fiddle for ya

Try
Width:inherit;

I have an absolute positioned logo on the bottom left of my website... BUT the problem is that ive positioned it to stick to the right of the page but it leaves a invisible barrier to the left of it that spreads across the page. So lets say a link is placed in alignment with that footer element, I won't be able to click it, the absolute positioned layer is spreading over it (even though nothings in it)
Heres my CSS for the logos position:
#basemenu {
margin-right: auto;
position: fixed;
bottom:0px;
width: 100%;
height: 40px;
text-align:right;
right:1%;
}
It sounds like you have an img inside of a <div id='basemenu'></div>. Is that right?
We could really use a block of HTML if you wouldn't mind posting it.
What I don't understand is why you can't target the logo itself with a bit of CSS like this:
#basemenu img {
height: 40px;
position: fixed;
bottom: 0px;
left: 0px;
}
Use the following block property display : none; to hide the block
Is there anyway for an absolute positioned child to expand to fill its relative positioned parent? (The height of parent is not fixed)
Here is what i did and it is working fine with Firefox and IE7 but not IE6. :(
<div id="parent">
<div id="child1"></div>
</div>
#parent { position: relative; width: 200px; height:100%; background:red }
#child1 { position: absolute; top: 0; left: 200px; height: 100%; background:blue }
That's easy. The trick is setting top: 0px and bottom: 0px at the same time
Here's the working code
html, body {
width: 100%;
height: 100%;
overflow: hidden;
}
#parent {
display: block;
background-color: #ff0;
border: 1px solid #f00;
position: relative;
width: 200px;
height: 100%;
}
#child1 {
background-color: #f00;
display: block;
border: 1px solid #ff0;
position: absolute;
left: 200px;
top: 0px;
bottom: 0px;
}

If I remember correctly there is a bug with how IE6 handles div height. It will only create the div to the height needed to contain the content within it when height is set to 100%. I would recommend two approaches:
Don't worry about supporting IE6 as it is a dead browser anyway
If that doesn't work, use something like jQuery to get the height of the parent div and then set the child div to that height.
fake it by setting the backgrounds to be the same colour so no-one notices the difference
You can achieve this with setting both the top and bottom attributes of the child.
See how this is done
At the bottom of that article, there is a link to Dean Edwards' IE7 (and IE8) js library that you should include for IE6 visitors. It is a JS library that actually MAKES IE6 behave like IE7 (or 8) when you include it. Sweet!

As far as I know, there is no way of expanding a parent element around an absolutely positioned child element. By making the child element absolutely positioned your are removing it from the regular flow of page items.
I recently built a 2-column website where the right column was absolutely positioned but the left column was not. If the left column had less content and a smaller height than the right column, the page would cut off the right column since it was absolutely positioned.
In order to resolve this, I had to determine if the height of the right column was greater than the height of the left column and if so set the height of the parent div height to the greater of the two.
Here is my jQuery solution. I'm not much of a coder so feel free to tweak this:
jQuery(function(){
var rightColHeight = jQuery('div.right_column').height();
var leftColHeight = jQuery('div.left_column').height();
if (rightColHeight > leftColHeight){
jQuery('.content_wrap').height(rightColHeight+'px');
}
});
