I am trying to use a mat-expansion-panel, however, with regards to the project I am working on the length of the title(s) I need to set on each panel could be very long and not predictable in most cases. Currently, if the length of the title text is too long then it goes out of the panel's bounds.
I know that I can set [collapsedHeight] and [expandedHeight] properties to adjust this behavior, however, I am trying to look for a solution that does not hard-code a value.
Here's a StackBlitz demonstrating what I am talking about. In that, the first expansion panel shows what happens when the title content is too long and [collapsedHeight] and [expandedHeight] is not set. The second expansion panel shows what happens when I set it to a static value - 190px.
What would be the best approach to achieve this?
I did a little change, you can see here. Let me explain:
I have set the height: 100% !important; in the mat-expansion-panel-header element. With that you are telling to that element that its height will be set by all the childs it has inside (title, description, etc).
And I have deleted the margin: 10%; It's better if you use pixels instead of % in margin or padding css properties.
Also you can make the title in one single line and set a ellipsis if it is very large, you can do that if you set in the title the next class:
.title {
white-space: nowrap;
overflow: hidden;
text-overflow: ellipsis;
}

I'm trying to build a multiline tooltip using [this example], I'm using it as a refernce because it involves functional components.
It works just fine, when its a short line of text, but doesn't go on a new line, which is something that I need.
I tried adding < /br > inside of the content, changing the content to jsx format and adding code below to the css file:
width: 200px;
word-wrap: break-word;
All it managed to do was decrease the tooltip backgronud width to 200px.
How do I change code in the example to go on a new line if content size width is going above the predetermined width?
How do I change code in the example to go on a new line if content size width is going above the predetermined width?
Besides setting the width to the e.g. 200px, you should also remove the white-space: nowrap; property because that is simply disallowing the text to break, even if it does overflow the container.

Good evening gentlemen (and of course ladies),
I'm currently experiencing some problems with CSS and the dynamic positioning of some elements in one big container. And I hoped that anyone of you could probably know the solution for my problem.
Maybe I just start with the explanation, which I will split in three parts to make it easier to understand. In the end of this post, there are two links, one for the steps to visualize them and one for the example jsfiddle for step two.
Step one:
There is one div.container which has the height 255px and a dynamic width of 33.3%. This container contains two divs: div.left and div.right. The div.left has exactly 150px width, which should bring the div.right to fill up the whole remaining space.
I already tried to solve it this way, which works, but not for the next steps.
.left {
float: left;
width: 150px;
}
.right {
overflow: hidden;
}
Step two: Now, there should be three different elements in the div.right, a h3, span and p element. The h3 and span should just behave like a regular element, and use the space they want to use (like for displaying text). But the p element should take the whole remaining height of the div.right. I achieved this single step by using the code in the jsfiddle link in the end of this post. And it looks really cool, but it's not compatible with the next step. As you maybe already guessed it.
Step three:
As the p.description element contains a description, I want to put as much information into this small element as possible. Therefor, I hoped to use overflow:hidden in combination with text-overflow:ellipsis, but this didn't work. Due to some strange reason, the p.description element was placed right of the h3 and span elements after I added the overflow:hidden style.
And additionally, there is an extra div in the footer of the div.right, which is div.btns. This div contains about 3 plain links and is placed absolutely in the right bottom of div.right, and I only want to have the p.description element to wrap the text around it.
Right now, I doubt, that all of these steps are solvable by only using css. At least, I wanted to have the positioning of the elements with css and the truncating of the text could be done in Javascript.
Is there anybody out there, who has an idea, how I could solve my problem?
Many thanks in advance!

In css: the max-height of the ellipsis in lines(52 & 61) are now 200px,
this can be changed with jQuery if you want to, on window resize or load.
max-height: 200px; /*This value could be changed with jquery*/
I have two divs nested inside of a div.
<div id='outter' class='one'>
<div id='inner'></div>
<div id='button' class='bttn'>Click me!</div>
</div>
The outter div's height is a percentage of the page. I'd like one of the inside div's height to be a fixed difference away the outter div (i.e. $('#inner').height($('#outter').height() - 35)), because the second inner div is essentially a button with fixed height (35). I'd like this to happen even when I change the height (through CSS triggers (:hover/adding a class/etc. so I can use Transitions) or otherwise).
I googled around a bit and saw Less might be an answer, but from what I can tell it compiles in to static values, but I still need to use percentages, since I want this app to work/feel the same on any screen size.
I have examples of what I'm currently doing/how I'm thinking about it in some jsfiddles.
Current 'solution': http://jsfiddle.net/L9NVj/5/ (End heights are what I want them to be, but the transition looks terrible)
Idealistic 'solution': http://jsfiddle.net/L9NVj/6/ (End heights are wrong, but the inner div hugs appropriately)
Potential solution: http://jsfiddle.net/L9NVj/7/ (This hides the inner div on click and then shows it again when the appropriate size has been reached)
Any help/thoughts/insights would be greatly appreciated!
Consider absolute-positioning the inner elements, since the outer's size isn't controlled by their size/position.
#inner {
position: absolute;
top: 2px;
left: 2px;
right: 2px;
bottom: 35px;
/* ... */
}
.bttn {
position: absolute;
bottom: 2px;
left: 2px;
/* ... */
}
Example: http://jsfiddle.net/L9NVj/9/
How about conflicting absolute positioning. To do it, you'd just need to set the top, bottom, left and right of the #inner element and then transition those. That will maintain the distances around the edges of the element, and allow other positioning as well.
Note that while you don't need to actually calculate the value in this case, in the future, calc() can be used to calculate a dynamic value in CSS. In that case, you could do something like height: calc(100% - 37px); to get the same effect.
CSS3's calc() is the answer you're looking for, in combination with a JavaScript fallback for browsers that don't support calc(). In your 'Idealistic solution' fiddle, change your CSS height definition to the following:
height: -webkit-calc(100% - 35px);
height: calc(100% - 35px);
While normally you should include all prefixes (and you still may need to, depending upon your level of browser support), according to Can I Use, the only browsers that currently need prefixing are -webkit browsers.
What I would do with this knowledge is the following: grab a feature detection script, I really like Modernizr and detect to see if calc() is available in the browser. Modernizr has a non-core detect for calc() that you can use. Use that CSS in your CSS file as the default, then using a resource loader such as yepnope (comes with Modernizr), load in a JS solution if calc() isn't available.
Of your JavaScript solutions, I'd probably suggest your "Potential Solution" option, but instead of jQuery's hide() and show(), set opacity to 0 and 1 and use a CSS3 transition to transition between the two. I'd also not rely upon a timeout, but rather use the transitionend JavaScript event.
I edited your first jsfiddle little bit i think that's what you wanted. Just added line.
$(window).resize(function(){$('#inner').height($('#outter').height() - 35)});
jsfiddle:http://jsfiddle.net/Qqb3g/
You may have to some workaround to make transition smooth when button the button is clicked.
you need to calculate the inner div in %, so it can resize belong outer div, change your js code to this :
//calculating inner div'x height in % of outer
$('#inner').height((100 - (33/$('#outter').height() * 100)) + '%');
$('#button').click(function () {
$('#outter').toggleClass('two');
});

I want to use a div as a background for a website.
If I use position:fixed and set the width & size to the viewport size the design breaks on mobile devices/tablets as they do not support the fixed position.
What's the best way to set a div as a static background, so that it works on mobile devices too?
I'm not entirely sure how you intend to use the background, but I created a loose way to do this here. The tacky background is applied to a div the size of the screen, and it will not move (as long as you're careful with what you put inside it). However, the same effect could be done just by direct styles on the body - I'm not sure what exactly you need the div for, so I can't guarantee this technique will work for your use case.
How it Works
With disclaimers out of the way, here are a few details on how it works. All content will have to appear within two divs: one outer one that has the background, and an inner one to hold all of the content. The outer one is set to the size of the page and can have the background applied to it. The inner one then is set to the size of the parent, and all overflow is set to scroll. Since the outer one has no scrollbar, any interior content that exceeds the size of the background tag will cause a scrollbar to appear as though it were on the whole page, not just on a section of it. In effect, this then recreates what the body is on the average web page within the "content" div.
If you have any specific question on the styles, let me know and I'll flesh out the mechanics in more detail.
With jQuery
I suppose there's still one remaining option: use similar style rules, but absent the ability to nest everything within the background, instead prepend it, and change it's position whenever the user scrolls, like so.
Then, just inject this code:
<style>
#bg {
width: 100%;
height: 100%;
position: absolute;
top: 0px;
background-image: url(http://cdn6.staztic.com/cdn/logos/comsanzenpattern-2.png:w48h48);
margin: 0px;
padding: 0px;
overflow: hidden;
}
</style>
<script>
$("body").prepend("<div id='bg'></div>");
$(document).on("scroll", function () {
$("#bg").css("top", $(document).scrollTop())
.css("left", $(document).scrollLeft());
});
</script>
modifying the style rules for the background div accordingly, and you should be good. It will not have a good framerate since this will always appear after the scroll paint, but you're running low on options if you have so little control over the rest of the document structure and style.
You don't have to use jquery. I was able to get this effect with just CSS.
You set the div just below the initial tag. Then apply the image to the html within the div. Give the div and id attribute as well (#background_wrap in this case).
...I tried this without applying the actual image link within the html and it never worked properly because you still have to use "background-image:" attribute when applying the image to the background within css. The trick to getting this to work on the mobile device is not using any background image settings. These values were specific for my project but it worked perfectly for my fixed background image to remain centered and responsive for mobile as well as larger computer viewports. Might have to tweak the values a bit for your specific project, but its worth a try! I hope this helps.
<body>
<div id="background_wrap"><img src="~/images/yourimage.png"/></div>
</body>
Then apply these settings in the CSS.
#background_wrap {
margin-left: auto;
margin-right: auto;
}
#background_wrap img {
z-index: -1;
position: fixed;
padding-top: 4.7em;
padding-left: 10%;
width: 90%;
}

Long File Name Inside A Div
when you see those long file names with firebug you will find a span that tell us ->
.FileName {
float: left;
width: 438px;
}
we have predefined width for this span!
q#1 : so why we have overflow in that div and how can i fix that ?
q#2(important) : is it possible to make that file name scrollable without showing scroll bars ?
edit
(with jquery or javascript or css)
thanks in advance
You have an overflow because this text can't break (there are no spaces):
R1DA029_APP_SW_1212_2395_GENERIC_KT_REDBROWNBLUE_CID52_49_DB3210
You could change the span's into div's and give them a height and an overflow:hidden.
Html:
<div class="FileName">R1DA029_APP_SW_1212_2395_GENERIC_KT_REDBROWNBLUE_CID52_49_DB3210 asangsm.com.rar</div>
Css:
.FileName{
float: left;
width: 438px;
height: 20px;
overflow: hidden;
}
I don't think it's possible to make that file name scrollable without showing scrollbars.
If you don't want a scrollbar, but do want to scroll, then the most apparent solution would be to use some javascript. If you're into jquery, here's some:
http://www.net-kit.com/jquery-custom-scrollbar-plugins/
I've tried one of them (http://www.demo.creamama.fr/plugin-scrollbar/), setting the div containing the text to overflow: hidden; and the div containing the scrollbar to display: none; to mimic your situation, and that gives me a scrollable div with no scrollbar.
However, I think from a UI point of view it's not the best idea to have a scrollable section without a scrollbar. At least something should light up (as with the Mac OS Lion scrollbars) indicating you can, or are, scrolling. You could style one of the javascript solutions out there to make this happen, for instance with a tiny scrollbar or indicator.
Short of using CSS3's marquee, I can see no simple solution. You would have to use Javascript.
As per avoiding the line break, you can use white-space: nowrap;.
