Cap element size to grid area when using align-item: start - html

I have a CSS grid with a scrollable element placed in one of the grid's areas.
What'd I'd like is for the item to shrink if the content is too small to fit the area. I did this by setting align-self to start.
This works great, until the content grows. The element resizes past the end of the grid area it's assigned to.
How can I use align-start but still cap the height to the height of the grid area? I would have expected this to be the default behavior.
One solution is to have the element stretch but then have a child element inside it that contains the actual content. The parent would have overflow: auto and the child would simply grow until it's too large for the container. Unfortunately, this kills the box-shadow.
I could put the box-shadow on the outer element in this case, but then it'll be too large when the content is small.
Any ideas what I can do here? I considered using some Javascript shinnanigans but I'm not even sure how I'd grab the height of the grid area from JS.
JSFiddle: https://jsfiddle.net/1kLenm5a/2/

Apparently max-height: 100% works. I could have sworn I tried that but I was messing with so many other settings at the same time I must have missed it.
Thanks.

Autoscrolling text animation in CSS not going all the way

I'm trying to scroll some single-line labels in a single-line fixed-width container.
What I've tried so far is:
Create a container with fixed dimensions.
Place a scrollable container inside and attach the animation.
Place the labels.
The animation partially works, but the scrolling doesn't go all the way to what is configured (translateX(-100%)).
The overflowing part (green color in codepen) that exceeds the fixed container width is ignored.
I've tried various display and flex field combinations, but noting.
Here is a codepen sample.
https://codepen.io/efthymiosks/pen/QWQGVGg
The issue is that 100% is the size of the element, not the content. What I mean by this is because the content overflows the element, 100% only refers to the visible width of the container.
You need to change 100% to something else such as 150%. Unfortunately, this means that you need to know the width of the contents before. The only other way that I know of is using JavaScript to calculate the width of the contents.

Flexbox not allowing scrollable area after collapsing other part

I'm working on a HMI using AngularJS(1.7.8) and Bootstrap in which there is four main panels : the navbar, a small up-left, a big bottom left and a big right one.
The expectation are that the small up-left one can collapse to become smaller and leaving more room for the big bottom left. I was able to do that easily using flexbox. Inside the bottom-left panel there is an area that is supposed to be scrollable when the up-left panel is visible. When it is collapsed the scrollable area is supposed to have enough room to display its content.
That last expectation is what I struggle with. The scroll area is not applying the overflow-y style attribute and its height is the whole content even though it is outside its parent (the bottom-left panel).
So far I tried playing around with flexbox, setting each panel as a flexbox, setting height and various other things but nothing seems to work. Unfortunatelly I do not control the content and won't be able to fix its height. Since it needs to expand, setting a max-height attribute doesn't work.
Here is an example on fiddle.
EDIT :
From #Pablo-Binar comment, it appears flexbox don't work that great with % height attribute. I haven't found anything in the doc unfortunately.
Also from #Pablo-Binar comment, one solution is to set a height in px to the root node giving flex attributes to the child and to the final one (the scrollable one) set an height in percentage (height:100%).
Use this code
height: 100%.
If that's to high use
height: calc(100% - 30px);
That should do the job.

How can I get an element to stay within the browser's window width when its content is wider?

I am trying to get a div to expand to fill its container without causing that container to expand beyond the browser window's width, as in this page. Click "Expand" next to "Stack Trace in the last entry.
What it's supposed to do is show a horizontal scrollbar.
What it's actually doing is expanding beyond the width of the window.
I can get it to sort of work if I give the <div class="stack"> element a max-width in pixels, but I want it to expand to fill no matter how wide the window is, without expanding beyond it.
How can I fix this layout? What's a general way with css to get an element to expand horizontally to fill its container while not going beyond the window's edge?
The Page is back on now!
I cann't get your table stuff sorted. There are some invalid width Parameters.
You should use div-Containers rather then tables to layout your page!
The workaround solution I came up with was adding a max-width to the expand/collapse div. It doesn't really prevent the table being wider than the window, but it solves 95% of the cases.
Don't use tables, use DIV's and for full width use
width: 100%;
This will always use up 100% of the browser window width.
You can provide you outer Div width:100% so it will take browser width. Or else you can calculate browser width with Jquery $(document).width(); and store this in variable and provide to your outer div.

Nested Div not fitting nicely into container Div

I have a dojox chart (chartDiv) that gets created within another container div (panelContainer).
Even though I have the width and height of the chartDiv set to be 90%, it either introduces scroll bars into the chartDiv, or if I dtart altering the padding and margin settigns for the ChartDiv, it will spill outside of the parent container.
I know this is going to be a basic issue, but I have been playing with lots of different CSS settings but nothing seems to solve keeping the chartDiv within the confines of the panelContainer (taking up 95% of the space)
This fiddle might help you spot where I have gone wrong.
When you make a chart (or a dojox.gfx canvas) without width/height, it will try its best to determine its dimensions from the container you put it in. It can get confused though!
In your fiddle's case, #chart has a known width, because it's a block element and inherits its width from panelBG which is 100% of panelContainer's width.
The #chart div doesn't really have a height though, since a block element is 0px tall until you put something in it (or add some style to it). As a consequence, (I think) the chart simply assumes a height of some proportion to the width.
In your CSS, I see you have a #chartDiv rule with width and height 90%. I'm guessing you intended that to be #chart. That wouldn't actually have resolved the problem entirely though!
Assuming you changed that, the chart would now use 90%x90% as width/height, but if you try it, you'll see that the labels/axis are still positioned incorrectly.
Because you've floated the title container to the left, the chart container starts on the same "line" and tries to have its content "float" around the title container. This skews the axis labels out of place (green), while the actual chart (svg/canvas, pink) drops down below the title container.
To fix this, tell the chart container to stay clear of floats on both sides:
#chart {
width: 90%;
height: 90%;
clear: both;
}
It isn't really necessary to float anything though, and setting the height to 90% isn't always ideal. I made a suggestion in an updated fiddle: http://fiddle.jshell.net/froden/WsrHs/4/ .
The differences are just that the title container is a div spanning across the top, while the chart container is absolutely positioned so that it fills whatever space is left underneath. You can then just set width/height on panelContainer.
Absolutely positioned elements are taken out of the normal flow. This is why some of the elements are expanding beyond their containers. I have a feeling your floats are involved in that, too, but the fiddle is a little too complicated and a simpler version needs to be made.

Keep an element visible, but prevent from overflowing its parent?

Is there a way to make an element not contribute to parent overflow, but keep it visible? Let me clarify
There is a watermark-like logo to be applied to a page in the manner below. It is supposed to be positioned partly outside the main content (dashed blue line)
I'm not aware of the option to set an element background in such a manner that it would persist as the browser window is resized horizontally, so I've just added a <div> with the logo as its background and position:absolute with the necessary offset relative to main content container.
Previously, the page would not get a horizontal scrollbar as long as the browser was wider than W1. Now, with an additional "watermark" element added outside of the main content box, the scrollbar would appear whenever the browser is narrower than W2
Is there something obvious I'm missing? A background setting, or possibly a neat margin workaround/
Update:
I've added a rough jsfiddle to illustrate the issue
Unfortunately, just because you nested the "watermark" div and positioned it absolutely doesn't make it outside of the document. If you put it outside of the document, the page will scroll (as you see).
To me, the first solution I think of is to move the watermark outside of the "content" div and apply the watermark to its parent container. I'm guessing you haven't done that because you need it to be relative to the "content" div, but it's something to try.
Also, the reason it scrolls is because the document has been overflow. The quick fix, yet not recommended, is to use "overflow-x: hidden;" on the parent container of the "content" div.
It's harder to give you a solution since you've stripped the rest of your HTML, and some "fixes" may not be as applicable if your structure is complicated in certain ways.
Remember that the width of your elements is greater than the actual "width" it includes padding & margins, if you have padding on your div reduce the "width" by the equivalent amount.
does that make sense? if you post the actual css & html it might be easier to give you a more detailed answer
additionally could you not assign the image as the background of the actual body element and set it to centered?
I've had a play with the code and come up with a possible solution for you.
set
body{overflow-x:hidden;}
then add
#media all and (max-width: 400px)
{
body{overflow-x:auto; }
}
as soon as your screen is smaller than 400px (the width of the div) your overflow:hidden will be overridden and you'll be given you scroll bars.
at this point you may also want to reduce the width of your watermark.
