CSS Diamond shape centric website issues - html

I've got an audacious project and would like some advice. I want to have a site that uses CSS Diamonds, I've attached an image to give a better idea of what I am looking at doing. Here are the issues I have run into so far:
The triangles are perfectly aligned until a submenu is added, then the right three shift to the right (this was working at one point). Also the li in which the submenu is under loses its diamond
The text on the submenu diamonds are not centered.
I cannot have the background image, then diamond then title. I have tried different z-indexs and it hasn't worked. (To see the menu titles, the background image needs to be removed, and the diamonds need to be -1 z-indexed)
Because I need to use spans to create the triangle text wrapping for the sidebar I cannot just make the sidebar div a diamond, so I still need to add the diamond in below it.
It would be great to have both the right text body and the sidebar text body wrap to the diamond, however I think this is not possible, therefore I reverted to just having the sidebar wrap.
Here is my HTML so far: I have commented out the submenu and my sidebar diamond attempt. http://jsfiddle.net/s4XXE/

Good news! I have solved most of my issues. Here is my updated jsfiddle: http://jsfiddle.net/s4XXE/1/ I will continue to work on fixing all issues. Any assistance would be helpful.
FIXED: I used the submenu class to correct the offset that was caused by the addition of a submenu.
FIXED: The titles do show up now. I think I added display:relative; to the CSS so that it accepted the z-index
FIXED: Changed the triangles on the menu to before instead of after so the triangles still show up on the menus with submenus.
BUG: The submenus are shown when the mouse gets close to the menu item. It should just be showing the submenus when the mouse is on the triangle.
BUG: On the menu items a link is only 'valid' when the mouse is over the text. It would be nice to have it 'valid' when it is over the shape.
BUG: The titles on the submenus and sidebar title are still not centered.
BUG: Changing the "Home" titles messes everything up. (need to adjust for changing content)

HTML Body is overflown

I'm trying to create a website where the first part is a video, on top of it is a navigation bar and description sentence. The second part is a div with a picture and a lorem ipsum paragraph. But the two-part is mushed together. Do you know why?
The first part is the video-container div. It contains a video, a navigation bar and some introductory words
The second part is the intro div which has an image and a paragraph side by side

You can make use of css flex property, in your case please add
.flex-container {
display: flex;
flex-wrap: wrap;
}
under your style tags and assign this class to intro class div as <div class='intro flex-container'>, will this worked for you?
you can easily wrap the .video-container and .intro divs with a div tag and give it style display flex and make sure you add flex wrap also.
Then just give your video and intro containers width 100%

Responsive Timeline

I need a responsive timeline with labels under each number (JSFiddle Example):
<ul>
<li>1</li>
<li>2</li>
<li class="active">3</li>
<li>4</li>
</ul>
And the CSS is the following:
li {
width: 2em;
height: 2em;
text-align: center;
line-height: 2em;
border-radius: 1em;
background: dodgerblue;
margin: 0 1em;
display: inline-block;
color: white;
position: relative;
}
li::before{
content: '';
position: absolute;
top: .9em;
left: -4em;
width: 4em;
height: .2em;
background: dodgerblue;
z-index: -1;
}
li:first-child::before {
display: none;
}
.active {
background: dodgerblue;
}
.active ~ li {
background: lightblue;
}
.active ~ li::before {
background: lightblue;
}
How can I:
1. Make it responsive so the distance between circles change on browser resizing?
2. How to add a label under each circle?
Have a look at the jsfiddle i've done for you excuse me if i understood anything wrong ask me if you need anything.

#Baransel gave you a solution, but to answer your questions...
How can I:
1. Make it responsive so the distance between circles change on browser resizing?
Put margin or padding in the CSS for the li or as the example above in the div within the li.
How to add a label under each circle?
Either in the html as #Baransel has done through the use of an tag, or appending it via the ::after attribute in the CSS content field. Likely putting the label actually in the HTML is the best choice for accessibility.

How do I clear a float only on mobile? And why is my media query for mobile affected when I remove the media query for tablets?

I'm attempting to make a simple HTML/CSS site from scratch for the first time and I'm trying to adjust it for cell phones and tablets.
But the main content is displaying beside the navigation bars when displayed on a phone set to the horizontal position. I don't know how to clear the float in a media query.
Also, when I delete the tablet media query from my CSS... it affects the cell phone media query. Why is that?

The issue is in media query at screen resolution of 1024px, the same way you used media query to hide display for image div in small screen resolution, using same way you can make such many changes in your media query. Use clear:both to align text properly after menu in tag main.
clear - The clear property specifies on which sides of an element
floating elements are not allowed to float.
#media only screen and (max-width: 1024px) {
body {margin: 0; padding: 0; background-image: none;}
h1 {margin: 0;}
nav {float: none; width: auto; padding: 0.5em;}
nav a {padding: 1em;}
main {padding: 1em; margin-left: 0; font-size: 90%; clear:both;}
footer {margin: 0;}
#wrapper {width: auto; min-width: 0; margin: 0; box-shadow: none;}
}
Check this jsFiddle.

How can I set a background to 100% width while having the text within it at another width?

I'm starting out with CSS, so I'm afraid to edit the code I already have. Part of it is main { max-width: 60em } for the text to be centered and a sticky menu. When I try adding .container { width: 100% } to another section like body or div, it messes up my sticky menu.
How can I make just one part of the page have a full width background?
(The issue is not about centering the look of the text, but the positioning on a page.) I want the text to be within 960px while having the background at 100% width.

I tried different things with the width, so I thought of doing the opposite. The following code worked! Thanks for the help, everyone! :)
.container {
min-width: 100%;
background-color: #aa4464;
}

css: zooming-out inside the browser moves rightmost floated div below other divs

I am seeing something strange in both firefox and chrome when I increase
the zoom level inside these browsers, although I see nothing wrong with
my CSS.
Here is the whole story:
I have a right-floated top-level div containing three right-floated right.
The three inner divs have all box-model measurements in pixels which add
up to the width of the enclosing container. Everything looks fine when
the browser size is 100%, but when I start making the browser smaller
with CTRL+scrollwheel or CTRL+minus the rightmost margin shrinks
down too fast and eventually becomes zero, forcing my rightmost
floated inner div to fall down below the other two!
I can't make sense out of this, almost seems like some integer division
is being performed incorrectly in the browser code, but alas firefox and
chrome both display the same result.
Here is the example (just zoom out with CTRL-minus to see what I mean):

Just to narrow things down a bit, the tags of interest are the following:
div#mainContent
div#contentLeft
div#contentCenter
div#contentRight

EDIT 1:
I've checked all measurements again and carefully plugged in numbers until they
satisfied the following equation for the three uniform columns in the main area
with uniform collapsed margin areas on all sides:
TEXT_AREA * 3 + MARGIN * 4 + BORDER * 6 = 960px (the width of the
wrapper)
TEXT_AREA = WIDTH + 2 * PADDING
BORDER = 1
subject to the margin and padding set to reasonable values of course,
and here are some numbers which seemed OK which solve these constraints:
TEXT_AREA = 290px
MARGIN = 15px
BORDER = 1px
PADDING = 15px
WIDTH = 268px
which translates to the following:
div#mainContent { float: left; width: 960px; padding: 15px 0; text-align: justify; }
div#contentLeft { height: 900px; float: left; margin: 0 0 0 15px; border: 1px solid black; padding: 15px; width: 268px; background: #ccc; }
div#contentCenter { height: 900px; float: left; margin: 0 0 0 15px; border: 1px solid transparent; padding: 15px; width: 268px; background: #E00; }
div#contentRight { height: 900px; float: left; margin: 0 15px 0 15px; border: 1px solid black; padding: 15px; width: 268px; background: #ccc; }
However even now that everything is uniform, I still get the problem that when I zoom
out the rightmost column falls down below the others. One solution is to do the following:
div#contentRight { height: 900px; float: left; margin: 0 0 /* 15px */ 0 15px; border: 1px solid black; padding: 15px; width: 268px; background: #ccc; }
so that now the right column has no right margin, but the visual result is the same.
Now, when I zoom out, the rightmost column does not fall down, but its right margin
is so small compared to the others, so really, there is still a small problem.
Edit 2:
OK, I've done some more searching and found an even better solution. The solution
consists in having the margins in between the div column elements the same and having
the left and right margin adjust automatically. In order to achieve this, I had to
do away with floats, and use "display: inline-block" which IMHO is much more suitable
than floats and was designed for the purpose at hand:
div#mainContent { padding: 15px 0; width: 960px; text-align: center; }
div#contentLeft { display: inline-block; vertical-align: top; height: 900px; margin: 0 0 0 0/*15px*/; border: 1px solid black; padding: 15px; width: 268px; background: #ccc; }
div#contentCenter { display: inline-block; vertical-align: top; height: 900px; margin: 0 0 0 15px; border: 1px solid transparent; padding: 15px; width: 268px; background: #E00; }
div#contentRight { display: inline-block; vertical-align: top; height: 900px; margin: 0 0/* 15px */ 0 15px; border: 1px solid black; padding: 15px; width: 268px; background: #ccc; }
div#mainContent section { text-align: justify; }
Now, at a normal zoom level all left margins will be 15px plus the last element's right
margin which will also be 15px. On the other hand, if I zoom out, there is some pixel
rounding going on, but the rounding is applied more or less equally on both sides,
which is somewhat better. This works in Firefox.
Edit 3:
Alas, I've tried reducing the in-between margins a bit, which makes the problem
go away with Chrome, but one of the div elements still drops down in IE10.
div#mainContent { padding: 15px 0; text-align: center; }
div#contentLeft { display: inline-block; vertical-align: top; height: 900px; margin: 0 0 0 0/* 20px increased from 15px */; border: 1px solid black; padding: 15px; width: 268px; background: #ccc; overflow: hidden; }
div#contentCenter { display: inline-block; vertical-align: top; height: 900px; margin: 0 0 0 10px/* reduced from 15px */; border: 1px solid transparent; padding: 15px; width: 268px; background: #E00; overflow: hidden; }
div#contentRight { display: inline-block; vertical-align: top; height: 900px; margin: 0 0/* 20px increased from 15px */ 0 10px/* reduced from 15px */; border: 1px solid black; padding: 15px; width: 268px; background: #ccc; overflow: hidden; }
div#mainContent section { text-align: justify; }
Edit 4:
I've come up with a solution which works in Firefox, Chrome, and IE10.
Basically, I've created three div wrappers around the three columns
and taken measurements again ensuring all measurements are symmetric.

This is probably caused by sub-pixel rounding.
As you zoom, your browser may calculate pixel values with fractions of pixels. As a result of rounding these values up or down, pixel-perfect layouts can break. (Different browsers handle this in different ways.)
I had decent luck converting your pixel values to percentage values.
Here are the values that worked for me:
div#contentLeft,
div#contentCenter,
div#contentRight {
margin-left: 1.1%;
padding: 1.56%;
width: 28.3%;
}
Edit:
Here's another method, which essentially centers the three boxes in div#mainContent rather than spacing them so tightly with margins. It allows them a little more room to flex when zoomed.
I removed the margin-left from div#contentLeft and added the following CSS to center the three boxes:
div#wrapper {
overflow:hidden; /* ADDED THIS TO AVOID HORIZONTAL SCROLL */
}
div#mainContent {
position: relative; /* ADDED THIS */
left: 50%; /* ADDED THIS */
float: left;
padding: 30px 0px;
text-align: justify;
}
div#contentLeft {
position: relative; /* ADDED THIS */
left: -50%; /* ADDED THIS */
background: none repeat scroll 0% 0% #CCCCCC;
border: 1px solid black;
float: left;
height: 900px;
padding: 15px;
width: 272px;
/* margin-left:12px; REMOVED THIS */
}
div#contentCenter {
position: relative; /* ADDED THIS */
left: -50%; /* ADDED THIS */
background: none repeat scroll 0% 0% #EE0000;
border: 1px solid transparent;
float: left;
height: 900px;
margin-left: 12px;
padding: 15px;
width: 272px;
}
div#contentRight {
position: relative; /* ADDED THIS */
left: -50%; /* ADDED THIS */
background: none repeat scroll 0% 0% #CCCCCC;
border: 1px solid black;
float: left;
height: 900px;
margin-left: 12px;
padding: 15px;
width: 272px;
}
The boxes remain floated on one row even when Firefox is zoomed all the way out.
