Automatically Animate/Scroll A Div Horizontally On Page Load

I have a seemingly basic question that I can't find any resources in what I am trying to acheive. I'm new to JavaScript and fairly mediocre at CSS.
What I am trying to accomplish is this. A page which can be displayed on a TV screen showing a list of sports results, overflowing to the right. I want the page to automatically scroll that div across to the right (which has a dynamic length depending on the amount of content) so it can see all the scores across all divisions and automaticaly scroll content to the right. When it reaches the end, pause, and then refresh (using Ajax) snapping back to the beginning.
I'm sure if I can be pointed in the direction of the right functions to use I can hook the various parts together.
Here's an example of something I am trying to run on page load that I'd like to scroll smoothly to the end over the course of 10 seconds, I just can't work out how to identify/set the "end" of the div.
$('#ScrollMe').animate({
scrollX: ??? //To div end;
}, 10000);
I think if I can solve this part, I can solve the rest.
Any pointers? Javascript, CSS.... open to anything!

You can use the .scrollWidth property to determine how far to scroll, subtracting the visible width will give a more accurate end point, eg:
(styles and animation time set to 2s, just to demonstrate what's happening)
$("#scrollMe").animate({
scrollLeft: ($("#scrollMe")[0].scrollWidth - $("#scrollMe").width()) + "px"
}, 2000);
#scrollMe { width: 100%; border:1px solid blue; overflow:auto; }
#inner { width: 6000px; border:5px solid red; height:20px; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id=scrollMe>
<div id=inner>
</div>
</div>

You just need to apply overflow: scroll css propertie, to the div you want to "overflow" the page width. So it will add a bar below the div, such as the default scrolling bar of every browser.
parentDivWithContentToOverflow{
Overflow: scroll;
}

This is a great example of what you need.
https://css-tricks.com/snippets/jquery/smooth-scrolling/
But you need to specify the div to achieve this.
If your requirement is only to scroll to the end of the page(which is right), then you can use your example. But you need to specify the pixel location to scroll to right. For that, you might need something like the below.
function getWidth(){
return Math.max(document.body.scrollWidth,
document.documentElement.scrollWidth,
document.body.offsetWidth,
document.documentElement.offsetWidth,
document.documentElement.clientWidth);
}

Bootstrap Collapse over an element

I'm using Bootstrap 3 to make a responsive website. However, I'm making a "portfolio".
You can see the website here as well as my "error".
http://basic-models.com/b/
Scroll down to "Our models" and click on "Informations". When you click on that button, it will collapse a new element below the profile picture of a model.
But that collapsible element is pushing the picture below the element to right for one column.
I guess I don't have to place code here since you can just right click > source code it.
Also, this is my first question on Stack Overflow, so I'm sorry if it is not formatted properly. Thank you for all the help.

You can change the CSS position attribute of the collapsing div to absolute. That way, the element will float over the below item - but you`ll have to apply styles a bit.
Try it like that:
.model-outer div.collapse {
position: absolute;
z-index: 1000;
background-color: white;
width:100%;
left:0px;
margin-top:10px;
}
You see, positioning and styles are not that good, but I assume you can start from there.

Since you are already using Bootstrap, I would suggest you to use default bootstrap dropdown . The problem with current code is that the div which shows the information is not absolutely positioned. So, whenever that div is displayed, it takes up the extra space and breaks the layout of the grid. Bootstrap dropdown uses absolute positioned div and hence it doesn't break the layout. Try using it and it will definitely solve this issue.

Portfolio Expander width - Jquery CSS

I've been playing around with changing the way my portfolio looks and I've been struggling with getting my expander to push elements down (like google images does).
My test is here: http://chris-carpenter.co.uk/new/
I've used this as a starting point to add a filterable option for my work:
queness.com/post/14577/create-a-simple-responsive-portfolio-page-with-filtering-and-hover-effect
This is what is causing the problems. I've found ways to create the filterable portfolio, and ways to create a static portfolio that has an expanding content section but combining them is blowing my mind. I can't seem to figure it out.
At the moment this opens and pushes elements down, but the width is limited by the parent div, so anything below & to the right doesn't seem to shift.
<div class="portfolio--expand is-expanded">
</div>
I'm now looking at inserting a content div at the end of the row clicked. Much like this.
http://jsfiddle.net/JfcAu/450/
I'm not experienced enough with JS to understand what's happening and apply it to what I have though. Could anyone help me achieve a filterable grid which has a click to expand option?
I don't expect to retain any current styling ofcourse, since I haven't changed it at all from the original source yet, I just want the function working.
This has been hurting my brain for ages.
Useful things I've looked at:
isotope.metafizzy.co/filtering.html
oriongunning.com/blog/thumbnail-grid-expanding-preview/

You might have to do some width adjustment, but this:
#portfoliolist .portfolio {
box-sizing: border-box;
width: 23%;
margin: 1%;
display: none;
float: left; /* <-- this is taking it out of the DOM */
}
has a float:left - that is taking it out of the DOM - you have to remove the float:left - and then adjust width to maybe 22% or something to let the expanded content push everything out of the way.

CSS positioning full width and height of multiple elements

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!

JsFiddle for step two: http://jsfiddle.net/S8g4E/1188/

Check this Jsfiddle: http://jsfiddle.net/Mohamed_nabil/7btp2/
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*/

Side Panel in CSS

I have a div called calendar that is inside a div called cal-container. The calendar has width:100% so currently it takes up the whole cal-container.
I need to add a side-panel div. This div will have a fixed width of 150 pixels. Thus, #calendar width should be #cal-container width - 150px. Is this possible with CSS or am I forced to use a table?
If it is possible, is there an example? I googled it but nothing like what I want came up.
The side-panel can be hidden and shown by click a button so adding padding will not work.
Here is an idea of what I mean:
The days part is #calendar, and the Unscheduled part is the side panel of 150px.
I tried floating the calendar left, and cloating the side panel right and giving it a width of 150px. But the idea is if I hide that div, the calendar should then take 100%.
Thanks
Like this, the blue would be side and calendar be the left, but calendar needs to take up the room side does not when hidden.

Result of float:

Got a working solution for you here.
The code to get this working basically hinges on the following structure:
<div class="sideBar">
...
</div>
<div class="tableWrapper">
<table>
...
</table>
</div>
Next, make sure the elements have these significant CSS properties:
.sideBar {
float: right;
}
.tableWrapper {
overflow: hidden;
}
table {
width: 100%;
}
What's happening here is that the .sideBar floats right, and takes up whatever space it needs to. Meanwhile, the .tableWrapper will take up whatever space is left by virtue of overflow: hidden. Finally, tell the table to take up 100% of its available width.
Click the button in the demo to see the table automatically resize.

All major browsers and IE10 support flexbox. Not supported < IE10.
