I'm working on a resizable page with a sidemenu to the right, and it almost works as supposed on this simple example:
http://pastehtml.com/view/1do8cy9.html
The problem though is that position auto and min-width dont react as expected. If you drag the browserwindow smaller than 500px (as the min-width is set to), the red sidemenu continues over the green content..
How do I make the sidebar stop when it reaches the min-width, fx 500px?
The absolute positioned div should be inside the min width div which should have position relative
Edit, better explanation:
For the sidebar: add top: 0 to the red sidebar and place it inside the min-width container.
For the container: replace the margin-right property with padding-right and add position:relative
I have a fix !
It's weird though:
body{
position:absolute;
top:0;
left:0;
bottom:0;
min-width:1300px;
width:100%;
overflow:auto;
padding:0;
margin:0;
}

I am using react-virtualized WindowScroller with CellMeasurer to scroll through a 100 sample records and by itself, it works great.
Now, when I place this component in a content pane with a frozen header and footer (using flex) above and below it, react-virtualized does not bring in additional data beyond the first page.
The structure of my container page is the same as the create-react-app template:
<div className="App">
<div className="App-header" />
<div className="App-intro" />
<div className="App-footer" />
</div>
and here is the CSS I use to freeze the header and footer:
html, body, #root {
width: 100%;
height: 100%;
margin: 0;
padding: 0;
overflow: hidden;
}
.App {
width: 100%;
height: 100%;
display: flex;
flex-direction: column;
}
.App-header, .App-footer {
flex-shrink: 0;
}
.App-intro {
flex-grow: 1;
overflow-y: auto;
}
FWIW, the official WindowScroller example accomplishes a frozen header using flex, but try as I might, I am not able to replicate it on my end.
I am at my wit's end after spending a whole entire day on this. I would really really appreciate any pointers to get this flex layout going with a functional window-scroller.
In the CodeSandbox you linked to (codesandbox.io/s/52j0vv936p)- window "scroll" events aren't reaching WindowScroller. That's because the window isn't actually what's scrollable, rather it's the middle "body" part. If that's what you want, you don't need to use WindowScroller at all and should remove it.
The only thing left that's broken is that your AutoSizer isn't getting a valid height because one of its parent <div>s doesn't have a correct height. For Stack Overflow convenience, here's the relevant bit:
Why is my AutoSizer setting a height of 0?
AutoSizer expands to fill its parent but it will not stretch the parent. This is done to prevent problems with flexbox layouts. If AutoSizer is reporting a height (or width) of 0- then it's likely that the parent element (or one of its parents) has a height of 0. One easy way to test this is to add a style property (eg background-color: red;) to the parent to ensure that it is the correct size. (eg You may need to add height: 100% or flex: 1 to the parent.)
Here is a diff to your sandbox that shows what I'm talking about and here is a fixed Code Sandbox demo.
I'm currently developing a site which requires headings as such:
My initial idea was to do this with border-bottom, but how would I limit the width of the border so that it doesn't go all the way across? The border needs to stop when it gets to the text.
Is this possible?
h1 {
background-color: #fff;
line-height: 1;
margin: 0;
display: inline;
position:relative;
z-index: 1;
}
h1:after {
content: '';
display: block;
border-bottom: 2px solid;
position: relative;
z-index: 0;
margin-top: -7px;
}
The length of the border is decided by the size of the element it is bordering. You could create another <div> inline with the text with border-bottom: 1px; and the other borders set to 0. You could then change the margin or width of the <div> to alter the length of the line. Note that you'd have to set a width, because an empty <div> has a width of 0 by default, so won't display.
Another possible (but not recommended) way to do it would be to use a <hr> but these are not well supported in HTML 5, so I would choose the first method personally.
A solution I can come up with is to give the title the same background-color as the page's background, and then to either transform: scale() the title up so that it overflows with the border of its parent, either scale the parent down so that its border hides behind the title's background.
See here for an example:
http://jsfiddle.net/WjRqC/1/
Oh, also, scaling can be replaced by making the title position: relative and moving it downwards a few pixels (and giving it a bit more vertical padding if you don't want the text too close to the line). Actually this is probably a better idea than scaling, because it's not CSS3, so it's more compatible.

I'm new to stackoverflow.com and this is my first post so:
I want to have a h1-text with underline. This underline will be an image and it should have a fixed width of 420px. The text in h1 will often be wider than the 420px, but sometimes shorter. Now I know that these are the solutions to get the underline as an image, but how do I set the fixed width for the underline only?
h1 {
background-image:url('images/hrBg.jpg');
background-position: 0px bottom;
background-repeat: repeat-x;
}
Create the background image with the width of 420px.
Then use the following css
h1 {
background:url('https://images.squarespace-cdn.com/content/v1/5834a5fd9de4bb511a531745/1572560269010-YEGGAHEJ1O3AG5OAMO7M/ke17ZwdGBToddI8pDm48kEnLsHrnzeww6Ind1smsg7N7gQa3H78H3Y0txjaiv_0fDoOvxcdMmMKkDsyUqMSsMWxHk725yiiHCCLfrh8O1z5QPOohDIaIeljMHgDF5CVlOqpeNLcJ80NK65_fV7S1UZMvWVOiG2zXPfa_FplZumXplNQ97KbZI2EjeHIoBACLnr1xKjsq_-rO8kOgOtwYvw/Burning-Up-BG.jpg?format=2500w') no-repeat left bottom;
min-width:420px;
}
<h1>Text here</h1>
This will ensure that the background is shown only once to with of 420px. I have added the min-width property in case the content of h1 is smaller than 420px. The no-repeat property ensures that the background is shown only once as we have set the length via the actual image.
I have the following fiddle for people to see http://jsfiddle.net/defaye/DhaHP/4/
The result on full screen: http://jsfiddle.net/defaye/DhaHP/4/embedded/result/
The problem I'm having is that when going past a certain width of resizing the window, the left column departs from the group. I need them to remain touching, with the centre column having a min-width 400 to max-width 800px, the sides width: 200px. The header should be 100% however.
Anyone know how to solve this problem? It is driving me insane.
Here is another example, compatible with IE6+: http://jsfiddle.net/DhaHP/12/
Result: http://jsfiddle.net/DhaHP/12/embedded/result
Abstract of the changes:
Changed #left and #right to be above the #center (#right before #left);
min-width and max-width on #container to 800px and 1200px respectively;
No float on #center;
margin-left and margin-right on #center equals the width of each side column;
float-left on #left and float-right on #right;
The only obs on this for IE6 is the min-width and max-width that doesn't work without a little hack or the use of IE7.js. On IE7, it works as should be.
Here's a working fiddle: http://jsfiddle.net/PhilippeVay/DhaHP/8/ (edit: now works with Chromium)
Modifications made:
HTML: #left before #center column
CSS: no relative positioning at all
display: table; on parent and table-cell on the 3 columns. This will be visually (and only visually) a table. Well, a table layout and not a table structure.
200px width on #left and #right
table-layout: fixed; on parent to switch the table algorithm to the one that respect dimensions as told by the author and not those guessed by dimensions of content of cells
Constrained widths for the parent min-width: 800px; (400+200+200) and on the grand-parent max-width: 1200px; (800+200+200) (edit: max-height on #container only worked on Fx, not Chrome). To my surprise, it works as is.
Compatibility: IE8+
You can play with inline-block with IE6/7 if needed (well, display: inline; zoom: 1; the IE6/7 equivalent of inline-block for outdated browsers)
Is there any way to achieve this in CSS3?:
height: 100% -110px;
My context:
You can't calulate it with pure CSS. (it will not work in all browsers, as mentioned by Litek ) But there is a organizational way to handle this, but you will need to wrap you element in a other one:
body {
height; 100%;
padding: 0 0 20px;
}
div#wrap {
background: #fff;
height: 100%;
padding: 0 0 20px;
margin: 0 0 -20px;
}
div#wrap div { //this would be your actual element
height: 100%;
background: pink;
}
What you want to use is calc() that is comming to FF and propably webkit, but don't count on it being widely supported anytime soon.
As for your example, maybe sticky footer will be some inspiration for you.
Edit
Nowadays it's well supported by major browsers:
http://caniuse.com/calc
Directly like that i'm not aware of any feature widely adopted to do that.
But there is a easy method to achieve the effect.
Put all element inside a container <div> with 'height: 100%', this container should have position relative so you can position the other elements inside it relative to its position. place the header on top and the footer at bottom with absolute positioning and calculate with javascript the height that the content div must have.
You can also subscribe the 'window.onResize' event to recalculate when the window is resized.
I know this is not a clean and prety solution, but is the one the you can make work well in almost any browser.
In the context it was given the 2nd div height value doesn't really matter. Actually it's only important where that div starts and where it ends.
In other words height = vertical end - vertical start:
#div2 {
position:absolute;
top:90px;/*20+50+20*/
bottom:20px;
}
