I'm trying to make a HTML "showcase". I am thinking of using elements like this:
<div id="index-showcase-tabs">
<div id="index-showcase-tabslide">
<div class="index-showcase-tab" id="showcase-tab-1">Item1</div>
<div class="index-showcase-tab" id="showcase-tab-2">Item2</div>
...
<div class="index-showcase-tab" id="showcase-tab-N">ItemN</div>
</div>
</div>
The showcase items are floated left, and I don't know their precise width, nor the number of them.
Problem is: if the combined width of the items is bigger than the container (index-showcase-tabs), I don't want them to break line (which they do by default). I want them in one line, and I want to hide the overflow and then let the user scroll them with javascript (not by scrollbar...).
How would I do that?
PS: There's not much css for the items yet. I only gave the slider a specific heigth:
#index-showcase-tabslide
{
height: 34px;
}
Edit: Here you can see my problem.
Edit2: explaining more with a fiddle: http://jsfiddle.net/TbSfj/19/
For this, you cannot use float: left. Instead use display: inline - this will have the same effect for what you want to accomplish, and it will not be constrained to the parent div in the DOM model.
check out this sexy control:
http://jsfiddle.net/SoonDead/U6QdQ/20/
this way made for my project, but I think it does what you want.
The tricks are:
Because you use a lot of characters that can "linebreak" and even forcefully disable linebreaks have different results in 1-2 browsers, I would recommend against it.
Instead make the overflowing width wide enough to hold all the elements easily, so if javascript is disabled it will not look ugly.
(I know that you are fine with jquery, so I use it within the example, also the outerWidth property in simple js has bugs in webkit (tends to be 0 in some cases).)
So you need to sum up the elements' outerWidth() and set the content holder's width, so you can use scrollLeft, and not overscroll.
There is no other trick, just a scrollTo function because calculating positions are not that trivial if you are new to jquery and you might want to use that.

I'm using bootstrap, angular and angular-ui-router
what I want to achieve is this mockup:
where the menu on the left is a navigation bar, a toolbar on the top, some breadcrumbs, content and a footer.
I can get all these elements in place. However, I need to populate the content with a variable number of elements from a rest data source. I want to wrap these nicely, so I am using the following angular / html
<div class="col-lg-12 ">
<div class="row">
<div class="col-md-4 " ng-repeat-start="item in $ctrl.items">
<div> card details here </div>
<div class="clearfix" ng-if="$index % 3 === 2"></div>
<div ng-repeat-end=""></div>
</div>
</div>
</div>
this works, and shows all the data. However, as there is more data than can fit into the div, scrollbars appear on the window
What I would like to acheive is to get the scrollbar to appear in the content div , like the screenshot
I have tried all sorts of css, like overflow: scroll-y, but can't figure it out.
Your problem seems to be related to dynamic heights. Using fixed heights (also %, vh, ... are useable), you can get that layout to work properly. There are a lot of solutions for that.
1. Using %
If you're going to use %, and that would by far be the best option, you have to start at the root tag which basically is <html>. After that you've to add the proper height value to it's child elements you want to use. Keep in mind to start at 100% and shrink your child element to the desired heights.
2. Using vh
The vh value is kinda same as %. You just don't need to set a height to every parent element. Demo
Note: You may have to check if that's working with your target browser.
3. CSS3 calc() function
Propably the newest method. You can calculate values through CSS(3), by using e.g. calc(100% - 100px). That's pretty cool though, but also isn't supported by every browser. See here.
4. Fixed layout
You could also use some fixed positionings. Setting up your footer, header and nav to position: fixed; would also keep up everything smooth and clean. I'd use a fixed layout in order to get that done, since I'd like it the most. Also it doesn't have any incompatibility with legacy browsers.
instead of overflow: scroll-y,
please try:
height:100%;
overflow-y:scroll
*giving it a height enables the scroll bar to appear.
I need to construct something like this: https://youtu.be/-pv77UW1w6g
But I'm facing problems to set div side by side with no space between them.
I made a wireframe to help to show my idea like the video above: https://dl.dropboxusercontent.com/u/9095670/multiple-divs.jpg
It's important to say that I'm using bootstrap and it's a responsive project. So, I don't want use fixed width or heigh (if possible) to do that. I've tried use display: inline, but I got many holes between them due the fixed min-height.
Thanks a lot for the help.
The issue lies in the fact that you markup likely has whitespace between the elements, the simplest way to avoid this is to set font-size: 0px; in the document body, then add a class to each child div that re-sets the font size back to whatever you want.
just do this:
<div class="wrap">
<div class="children">1</div>
<div class="children">2</div>
<div class="children">3</div>
</div>

Ok here you go.
You can comment out the keyframes, but I have put a bit animation in it, your video made me:-).
To explain this...as you see, there is no height declaration on the divs, only on the main wrapper div. And on the img tags, for demo purposes.
As you can see the divs will adapt height to whatever content is placed in to them.
Same for the pictures, you make them the size you want.
With the flexbox layout as it is there, I make the divs being placed as column, i.e. vertically. There is a height declaration on the main div, this one you will need if you want to display it like this, but only this one, without a height on main div, flexbox would never create a next column, it would just stack them one over the next. This way, as soon the height is reached, it creates a new horizontal column. This would be possible in other ways as well and takes some understanding of the flexbox model, do look into it, i thinks it is the future of layout.
And you set a width on the children class, i set it to 30% here, for 3 rows(flex will still create a 4th,5th etc, but these would fall out of the wrap div, so, a bit calculation is needed on your part.
Play around with it and see what happens if you change the children class width, or put more/less text in it, careful with margin, margin is bit odd with flexbox, this is beyond the scope here though.
Do not be afraid when flexbox creates a new row, don't try to fix it with margins when it looks odd(new or od row having a gap etc, you will see what i mean).
And this will be fully responsive as it is.
* {
box-sizing: border-box;

If you have any question, ask anytime.
Thanks for all help, but I solved my problem with Masonry as hungerstar said. The Masonry is good if you're using Angular.js too.
This probably was answered somewhere, but I can't find it :s
My question is about dynamic resizing of divs based in percentages.
Please look at code example below for the examples and possible solutions I made.
I ask if there is a better way to do resizing?
More detailed explanation:
Say I am writing a plugin that people can insert in their pages. (Imagine login form).
I go ahead and design the plugin's divs. I use media queries to achieve desired look for different devices. I work on a div straight inside of a 'body' element.
I use percentages for design (I like percentages). Say I set div to 80% width.
Now I give this plugin to the user. User goes ahead and puts the plugin's div inside of another
div that is 100px in width. Now everything looks awful. (80% of 100px is not a lot [80px]).
And of course I want user to put my plugin inside of whatever small-width divs that he have.
The solutions I saw so far to this problem was to create a holder div of certain width - say hardcode 300px. (ex - jQuery UI's Datepicker div; Meteor's login widget div). And then code to it always knowing the 300px width that I set before is not going to change.
But I don't know how good of a solution this is.
Moreover if I decide to go with hard-coding width, my plugin would need width of ~ 1000px. Because I want div to resize with media queries.
And if I go with hard-coding width (say holder div of 1000px width) and put it on a page, the page will have horizontal scrolling. And you cannot simply hide holder div (parent div) and have child to show at the same time. So this requires setting position:relative for holder (parent) div, putting it outside of window, and use same for child div - position:relative with same offset in opposite direction of parent offset.
I hope I am being clear so far and have not confused you!
A code example to illustrate what I am talking about:
http://jsbin.com/ifawez/18/edit
#cimmanon's comment cleared things out for me.
The problem is with lack of HTML/CSS "tools" available at the moment. Since responsiveness came into play fairly recently there are not a lot of CSS-native tools to accommodate changes in dimensions.
For instance media-queries exclusively work with width of window/document and not of other elements such as divs.
The solution I currently employ is using Javascript to determine width of a div and resize accordingly.
What I resize is the number of columns I want to display (I use Multi-Column module as suggested by cimmanon) which is pretty stable on webkit browsers. Since it is all done in Javascript (and jQuery's Sizzle) I keep an array of sizes like so:
var widthArray = [
{min:0, max:250, columns:1, secondary:false},
{min:251, max:350, columns:1, secondary:true },
{min:351, max:479, columns:1, secondary:true },
//more div sizes
];
// more code here
$(element).css({
"column-count": object.columns,
"-moz-column-count": object.columns,
"-webkit-column-count": object.columns
});
This is sort of like media-queries, but allows to work with width of html elements, not screen size alone.
Additionally I follow the way jQuery UI displays its components: using position relative/absolute.
.outer_div {
position: relative;
}
.inner_div_with_elements {
position: absolute;
z-index: 1010;
width: 99%;
float: left;
overflow: hidden;
...
}
.inner_components_displayable {
position: relative;
display: block;
}
.inner_components_hidden {
display: none;
}
So in Summary:
Media queries alone work with size of screen, and resizing of any inner element can be done in percentages to the screen size. They can be of huge help, but you turn into making your components work either with percentages based off screen, or specifying something like min-height and !important (as suggested by #Octavian)
Javascript manipulation of elements is currently easier, but is a costlier alternative (jQuery SIzzle is pretty slow)
A lot of libraries (ex. jQuery UI) use Javascript together with position relative/absolute to make sure their components/plug-ins will work nicely on all users' screen sizes.
I ended up combining position with javascript to emulate media-queries and multi-column design at the same time for responsiveness.
Thanks everyone who participated!
If I am reading this correctly, the main issue here is that it can potentially become too small based on where the code is located.
So why not just add a min-width property with !important? That way you can still base the size off of the parent container, but be sure that it doesn't get too small and ugly.
Potentially, you could even have a script to base the width off of the parent div and the min-width off of the screen size.
So I'm inspecting this site: http://www.grittirollo.it/ and it appears that the content that slides out has a fixed height. Is there no way to set this dynamically?
It appears as though the developer measured out how tall each portion of the sliders' box model would be when rendered, and then multiplied it by how many rows there were. From there, he/she set it manually in the CSS.
Elements on a webpage can typically be measured with their scrollHeight JavaScript property (element.scrollHeight) however some browsers don't have this and some browsers do it differently from others. (I believe Firefox's has to be done recursively down the tree of elements and Safari just uses the outermost element.) This should be possible without manually setting the height using JavaScript, you just may have to conditionally code it to work with all the browsers you want to support.
I don't see why it's necessary to set it dynamically. If the stuff is float:left; and they put a <div class="clear"> at the bottom of a hide-able section, you would be able to see the contents of that section when it was un-hidden with JavaScript. You could then adjust the layout with padding and margin to make it look pretty.
Or, they could have also used position:relative; and position:absolute; to layout the hide-able sections. It comes down to preference.
I have been using a lot of position:relative; in my design, I just find it the easiest way to get everything where I need them to be.
However, the more items I add on my site (each one with their individual div) each one ends up further and further at the bottom of my page, so I have to manually position them higher.
This leaves a lot of empty space at the bottom, and I thought that adding height: 1000px; would limit the scrolling a bit, but this method doesn't seem to work.
I've even tried adding height: 1000px; to the wrapper and it's still not working.
How can I limit vertical scrolling, to the number of pixels I choose?
Thanks so much in advance.
Wait, so you are creating a div, using position relative to move the content of the div to the correct location, and the issue being that the div tag itself is still in the same place and creating a vertical scroll even though there is no content there?
If so you should look into floats.
Here are some tutorials.

Learn CSS Positioning in Ten Steps
You can specify both the height and the overflow:
.someClass
{
height:1000px;
overflow:scroll;
}
The most common values for overflow are scroll, auto, and hidden.
To limit the distance someone can scroll, I think you'd need to use JavaScript. I'm not sure how, but I can't think of anything in CSS that would do that.
If you are looking to set when something should scroll instead of just be cut off or expand the tag, use overflow:auto;.
