I want to make a div that follows the viewport. I am not able to use fixed positioning. For some reason the div doesn't follow the viewport properly, it always 'lags' behind, especially when changing scroll direction. You can see what I mean on plunker here.
That is the first part of the problem. The second is that I need the div to immediately move into the viewport when it appears. (Clicking anywhere in the output panel in the plunker will toggle the div to appear). The *ngIf part of the appearing is important because in my actual app I am using a component with entry animations instead of a div, so no [hidden] I'm afraid.
So why can't I use fixed positioning?
Basically, fixed positioning causes the element to calculate the width differently to its sibling elements when the viewport contains scrollbars. I also can't use the overflow: scroll trick on the element because it has shadows that get clipped by the viewport. It also looks ugly having two scrollbars.
Here is a fixed centered div in a wrapper using flex.
Demo Here
#wrapper{
position:absolute;
width:100%;
height:100%;
position:fixed;
display: flex;
justify-content: center;
}
#my-app{
position:relative;
width:50%;
height:50%;
background-color:green;
}
<div id="wrapper">
<div id="my-app">
</div>
</div>

Hi I tried all possible css combinations i can think of ,but i cannot manage to create a layout like this.
everything scrolls including navbar and Tab controlls.
<el-row>
<el-menu class="el-menu-demo" mode="horizontal"> ..</<el-menu>
</el-row>
<el-row>
<el-tabs>
<el-tab-pane>...</el-tab-pane>
<el-tabs>
</el-row>
final expected outcome
This has nothing to do with Vue.JS, but it's just plain CSS that is of problem here.
Typically, to have such "full-window" layouts with fixed elements (like navbar, footer), it's best to use absolute positioning for these elements.
I've created a small JSFiddle that creates such a layout:
https://jsfiddle.net/5wgb94kv/
Basic ideas:
the navigation bar is positioned absolutely to the top of the window with a fixed height (in CSS: position:absolute; top:0; height:25px;).
the tab bar is also positioned absolutely to the top, but below the nabber. (CSS: position:absolute; top:25px; height:25px;)
the footer is positioned absolutely to the bottom (CSS: position:absolute; bottom:0; height:25px;)
the content is positioned absolute as well, with the correct insets from top and bottom, and with overflow-x set to scroll. CSS: position:absolute; top: 50px; bottom:25px; overflow-x: scroll;
See the jsfiddle for the full css details.

I have this CSS for my website's container:
.graybox {
padding: 0 30px 30px 30px;
background: #ededed;
position:absolute;
left:0;
right:0;
}
Then I have a container on top of that to center that info.
The .graybox container spreads the width of the page like I want but now my footer div is hidden, according to firebug is it actually behind? And up on the page?
Is there a fix for this?
While I'm here can anyone explain the white space on the right side of the page. It comes into effect once the page is resized smaller.
You can use the CSS z-index property to make sure your footer is in front of the content. Z-index only works when the element is positioned though. So make sure you add position:relative to your footer
#footer{
position:relative;
z-index:999;
}

EDIT
Just checked out the code of your website, and I don't understand why your graybox is positioned absolutely, this will only make things more complex. The same goes for your menu, why position it absolute, why not just add it in the right order in the HTML in the first place?
EDIT
If you want to center your content but with a background that has a 100% width then you can simply add a container div like so:
HTML
<div class="container">
<div>lorem ipsum....</div>
</div>
CSS
.container{
background:red;
}
.container div{
width:400px;
margin:0 auto;
background:yellow;
}
See JSFiddle here: http://jsfiddle.net/HxBnF/
Currently you cannot do this because you have a container which you set at 980px, don't ever do that unless you are sure you don't want anything to wrap over it, like in this case the background of a div in that container.
in the div style, just assign a z-index value greater than any other z-index such as
.divClass{
position: absolute;
z-index: 1 //if other elements are still visible chose a higher value such as 20 or even higher.
}
I have a centered wrapper with following CSS:
div.wrapper {
width: 1170px;
padding-left:30px;
margin-top: 80px;
margin-bottom:20px;
margin-left: auto;
margin-right: auto;
position:relative;
background-color:black; }
inside i have a div with following css:
position:absolute;
top:-26px;
left:517px;
height:63px;
z-index:3;
inside of this div is an image which has 759px width, that makes the wrapper grow larger and makes the browser show a v-scrollbar on lower display resolutions.
what i want is to make the image go outside the wrapper but prevent the browser from showing the scrollbar, so that the right side of the image is only shown if your browser window is large enough and the wrapper keeps its 1200px width. i can't make it a background image because it goes over some of the other content.
something that is compatible with >= IE7 would be nice.
i uploaded a pic of the page to show what i mean:
http://img153.imageshack.us/img153/6070/hpx.jpg
the blue box is the wrapper, it has 1200px width and is ALWAYS centered in the window (unless then window is smaller than 1200px, then it scrolls)
the red box is the image (the green bar is not part of it)
You can set overflow: hidden to the wrapper so that content that exceeds the dimensions of wrapper will not be shown.
see overflow
You are looking for #your_div { overflow: hidden; }, if you want your content to be hidden. Or #your_div { overflow: visible; } if you want your content visible outside the div.
The only method that springs to mind given your requirements is to move the inner element out of that wrapper div and position it in relation to the entire window:
<body>
<div class="abs">the div with the image</div>
<div class="wrapper">the wrapper div</div>
</body>
Unfortunately, this probably means you can't position it very well. You may need to use Javascript to get the width/height of the page and/or the position of the wrapper div, and calculate the offset accordingly. (You'll find questions on Stack Overflow for these bits.)
The problem lies with the img being inline. Not tested but you should 'display:block' the image and then float it or absolutely position it.
I'm braindead on this and I know it's simple.
There's a header div, appears fine. There's a left-sidebar div, appears fine with top snuggled up to header div.
Then there's a main content div. There is an image and h1 which appear like you would expect up against the header div, but then a large gap appears until the navigation (in a nested div). Navigation is correctly in the main content div, but top of this div always aligns with bottom of sidebar content.
I've tried mixtures of clear:left and both and floating and whatnot. If inside the html I move the sidebar div below the main content div then the main content has no gap but the sidebar has a big top gap and appears flush to the bottom of where the main content nav ends.
What am I missing here, thanks in advance!
Are you setting any widths (or padding, margin, border) which might make your problematic div too wide to fit?
Remember that if you are doing something like :
width: 100%;
border: 1px solid;
Then your element will take up 100% width + 2 pixels.
It sounds like you have your sidebar occuring first in the source order.
If you have the two divs (sidebar, main) floated in different directions, then look at the width avaiable they are sharing. Reduce the width of one div (you should have width set on your floats) until their combine width, including padding, margin, borders fits in available space. (I will only use width in my example for brevity).
When this effect happens, in my experience, the one occurring later in the source order is the one that gets prevent from sliding up into it's spot by too much width.
<div id="container">
<div id="header">head</div>
<div id="sidebar">side</div>
<div id="mainContent">main</div>
</div>
Width of #sidebar & #mainContent too wide (#mainContent gets bumped down):
#container{
**width:950px;**
margin:0 auto;
background:blue;
}
#mainContent{
float:right;
**width:651px;**
background:red;
}
#sidebar{
float:left;
**width:301px;**
background:green;
}
Width of #sidebar & #mainContent fit inside container:
#container{
**width:950px;**
margin:0 auto;
background:blue;
}
#mainContent{
float:right;
**width:650px;**
background:red;
}
#sidebar{
float:left;
**width:300px;**
background:green;
}
btw...if you floated the two elements in the same direction, but their combined width is too wide, the last one in the source order would fit underneath the above floated element.
Does your h1 or img have a top margin? It will stick out of the top of the mainContent div and push it down.
I have a div with two nested divs inside, the (float:left) one is the menu bar, and the right (float:right) should display whatever content the page has, it works fine when the window is at a maximum, but when i resize it the content is collapsed until it can no longer has any space, at which it is forced to be displayed BELOW the left menu bar, how can I make the width fixed so that the user may scroll when resized?
(css width didn't work, i alternated between floating the right content and not), here is the code:
<div style="width:100%">
<div style="float:left; background:#f5f5f5; border-right:1px solid black; height:170%; width:120px;"></div>
<div style="margin-right:2px;margin-top:15px; margin-bottom:5px; width:100%; border:1px solid #f5f5f5"></div>
</div>
I only need to have this working on Interner Explorer for now.
This should do it (container is the parent div containing that 2 divs):
.container {
width: 1024px;
display: block;
}
You may want to set a width on the containing div and set your overflow property
#containing_div {
width: 200px;
overflow: auto;
}
Also use the min-width property on the page if that makes sense, however that CSS property doesn't really work with IE6, this is usually what I do in that situation (supporting Firefox, IE7, IE6, etc)
#container {
min-width: 1000px;
_width: 1000px; /* This property is only read by IE6, which gives a fixed width */
}
Well, putting a width or min-width property is the way to go.
Now, without an example, or a link of the actual page, it's a bit tricky to answer.
Simply don't make the right div floating. Menu is already floating left of any other content. Just set a left-margin for the right div so the content in that div won't be wrapped around the floating div.
if the two divs are taking up 100% of the available width, could try to use percentage width and display: inline with a further div with a fixed min-width/width (boo IE) inside where required.
this is rather difficult without some HTML to go on
Your containing div should have a width wide enough to contain both inner div's
So if your two inner div's are 300px each and assuming you have no margin/padding on them then you should set the outer div to be 600px;
I'm a bit confused:
Fixed width means the width of a node will not change. Never.
You say you want to scroll when the screen gets too small for your content, so I think you mean the exact oposite of fixed width.
If my assumption is right, you could as mentioned before go for the percentual widths.
Watch out width the suggested "min-width" solution because it is not supported all that well.
<div id="container" style="width:100%">
<div id="primaryNav" style="float:left; width:150px; background-color: Orange">someNav</div>
<div id="content" style="margin-left: 10px; background-color: Red; overflow: auto;">
