I am trying to build a layout of buttons. I have worked at it for a while now, but I doubt my code would be helpful in understanding my problem. I have included the specs of the buttons on the image below. If you guys could show me how to make this layout it would be greatly appreciated.
Start with creating container and appropriate divs inside.
<div class="container">
<div class="blue"></div>
<div class="center">
<div class="red"></div>
<div class="yellow"></div>
</div>
<div class="green"></div>
</div>
then you have to position them and set particular width.
body, html { height: 100%; }
.container { height: 100%; }
.container > div { float: left; }
.center { height: 100%; width: 33%; }
.blue { background: blue; width: 33%; min-height: 100%; }
.red { background: red; height: 50% }
.yellow { background: yellow; height: 50% }
.green { background: green; width: 33%; height: 100% }
you can alternativly use flex box to get rid of float: left
.container { height: 100%; display: flex; }
Demo: http://jsfiddle.net/eLq0770h/
The way I would approach this is to make three DIV's side by side to make the three columns of your design. (the blue column, the red-and-yellow collumn and the green collumn)
You can then use two more DIV's to split the middle column in to two rows.
Your code would then be structured as follows
<div id="site">
<div id="leftcolumn">
CONTENT
</div>
<div id="middlecolumn">
<div id="middletop">
CONTENT
</div>
<div id="middlebottom">
CONTENT
</div>
</div>
<div id="rightcolumn">
CONTENT
</div>
</div>
You can then use CSS to set the widths and heights of these DIV's.
I don't know if this is the right way to do this, but this is how I do it.
Your code looks great. Here's how I would approach the project http://codepen.io/dfrierson2/pen/RNoWZe.
First I set the wrapper to 100% width then i centered the container with margin: 0 auto; I add a width to the container of 600px and set the height to auto and gave it a css selector class of overflow: hidden so that the container will expand with the content of the divs. I would use Bootstrap as a frame work because it is a responsive frame work with great starter code.

It also has great pre style navs and buttons http://getbootstrap.com/components/#btn-groups

You want the img to fill the height of its container which has class .img-container.
At the moment you have set the width and height of the img element to 100px. This gives a small image and one that may be distorted if the original is not square.
To make the image fill the full height but keep its original aspect ratio replace the .img-container img CSS settings with:
.img-container img {
height: 100%;
width: auto;
}
This may not be what you want if some of your images are more landscape than portrait for example. Depending on the image aspect ratios compared to the container's you may get the image cut off at the sides.
If you want to ensure that you always show exactly the whole image then investigate object-fit: contain This may give you white space either top and bottom or at the sides if the ratios don't match.
If you want to always fill the container, but without image distorion then investigate object-fit: cover. This will cut off top and bottom or the sides if it has to. You will need also to look at positioning, often center will do what is needed but may not work for all your images.
This is correct answer

I am currently creating a web-page where popup boxes are opening with dynamic content.
The popup itself should be maximal 98% height of the window -> no content goes on small devices in the overflow.
The content can consist of different elements which are floating and their width is managed by bootstrap columns. Their height should be given by their content, but not exceed the height of the popup. These content boxes can float under each other depending on screensize.
Due to the fact that all content is dynamic and therefore the heights are unknown until all is rendered, there could be scrollbars in almost every box.
html,
body {
float: left;
width: 100%;
height: 100%;
margin: 0px;
padding: 0px;
font-family: "Roboto Condensed", sans-serif;
overflow-x: hidden;
}
.clearfix:after {
content: " ";
display: block;
height: 0;
clear: both;
visibility: hidden;
}
* html .clearfix {
height: 1%;
} /* Hides from IE-mac \*/
.clearfix {
display: block;
}

The example code is only working, when you add a specific height to #dynamicPopup (for ex. 400px).
Is there any way to solve this only with CSS and HTML?
your #wrapper must have position: fixed; so it's height is relative to window not the body. then #dynamicPopup gonna work the way you expect. this is how popups (modals) work.
here's a good example of what you're trying to achieve:
https://codepen.io/jzilg/pen/vEmQrm
and I have no idea why you have floated your html and body. I've never seen something like this before. try to avoid it.
html,
body {
margin: 0px;
padding: 0px;
font-family: "Roboto Condensed", sans-serif;
overflow-x: hidden;
}
#wrapper {
position:fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
.clearfix:after {
content: " ";
display: block;
height: 0;
clear: both;
visibility: hidden;
}
* html .clearfix {
height: 1%;
} /* Hides from IE-mac \*/

I am newbie with CSS; so, I do not want to use CSS frameworks.
After reading some questions about fixed header and footer with CSS (on StackOverflow), I tried to create a HTML layout, as this:
In this layout, both header and menu are fixed.
I have created an HTML file with 2 column: left for menu, right for content. But, it comes with an scrolled-menu:
#menu {
width: 33%;
height: 100%;
float: left;
}
#page {
width: 66%;
height: 100%;
float: left;
}
#header {
width: 100%;
height: 100px;
position: fixed;
}
#content {
width: 100%;
position: absolute;
top: 100px;
}
#footer {
width: 100%;
height: 100px;
position: fixed;
bottom: 0;
}
<div id="menu">
MENU
</div>
<div id="page">
<div id="header">Header</div>
<div id="content">
<p>Some content...</p>
</div>
<div id="footer">Footer</div>
</div>
When I add this line: position: fixed; in #menu, the layout will be broken. Could help help me to fix it?
Currently you could use the Tag directly as <header> <body> <footer> you need to establish position : block. I would like to recommend that you uses a Framework like Bootstrap, today is commonly uses for design webpages, if you are new un webpages it Will be useful for you

I want the h3 and the button to be vertically aligned in the div, and I've tried setting style to vertical-align:middle but it doesn't work. What should I do?
EDIT: It seems my original question was unclear. I meant that I want the header text and button to appear on the same "line", but to be aligned vertically on that line. Right now, I can get them to be on the same line but the text and the button will be aligned by the top edge rather than the center.
Weave: http://kodeweave.sourceforge.net/editor/#0def3ea11664636810328b98a8780ed2
You didn't post your css so I don't know what you're working with. So here's a quick note:
NOTE: vertical-align only works for display: table-cell; and display: inline; elements (It also applies to ::first-letter and ::first-line).
Here's a simple solution using display: table; on the parent and display: table-cell; for what you want vertically centered.
If you want your button centered you have to remove the pull-right class, or you can add another class after it and then override it's css. (Simple solution, just remove the pull-right class.
Edit: So you want the button in the same line as your h3 tag right?
Well before I show you how to solve this remember that h1-h5 tags are all display: block; elements meaning they will always embed as a new line. (Like a paragraph <p> tag) So you need to tell the h3 tag to display either inline or inline-block.
Here is my revised weave: http://kodeweave.sourceforge.net/editor/#7b9839fb7971df2a27b7af895169ad8a

Not really clear what you mean by The width of the cols are breaking with the layout.
Try it this way :
html, body, .container {
height:100%;
width:100%; /*keep html and body 100% */
margin:0;
background:lightgray
}
.container {
display:table;
width:calc(100% - 260px);/*keep container 100% - 260px */

I don't quite understand; you want the container to be fluid, but then you have columns within it that have a fixed width?
How you could do it is:
<div class="header"></div>
<div class="container">
<div class="secondary-aside"></div>
<div class="content">
<div class="col-sm-4"></div>
<div class="col-sm-4"></div>
<div class="col-sm-4"></div>
</div>
</div>
With the following CSS:
html, body {
height: 100%;
}
.header {
height: 60px;
background: blue;
width: 100%;
}
.container {
overflow: auto;
height: 100%;
}
.secondary-aside {
width: 25%;
float: right;
background: red;
height: 100%;
}
.content {
width: 75%;
float: left;
background: #777;
overflow: auto;
height: 100%;
}
.col-sm-4 {
height: 100%;
background: yellow;
width: 33.3333%;
float: left;
}
Would that help?
I don't understand why you use so much of custom styles in BS.
