Display an background image trough table cells?

I want to set a background image on the floating bar on the bottom of my page: https://hartbodenreiniger.info/.
But sadly the background image gets cutted by each table cell..
I already tried two things:
1.Convert the table to divs and set the background image. This is working but I cannot display the button in the middle and center of the floating bar. This is needed to convert a table to divs:
jQuery('#wpfront-notification-bar > table').replaceWith( jQuery('#wpfront-notification-bar > table').html()
.replace(/<tbody/gi, "<div id='table'")
.replace(/<tr/gi, "<div")
.replace(/<\/tr>/gi, "</div>")
.replace(/<td/gi, "<span")
.replace(/<\/td>/gi, "</span>")
.replace(/<\/tbody/gi, "<\/div")
);
How can I center the Button?
Or my second solution was to create a overlay div and set this div to display:absolute; with an background image. But same problem. How do I center the button and also there is the problem that the overlay wrapper is above the text..
I think way 1 is the better way but how can I center that?
Do you have any idea or any other solution?
Kind regards

You can use line-height property. Try the code below and see the differences
.container{
height: 100px;
text-align: center;
border: 1px solid black;
}
.the-button{
height: 100%;
line-height: 100px;
}
button{
height: 30px;
}
<div class="container">
<div class="the-button">
<button>Hello</button>
</div>
</div>
<div class="container">
<div style="height:100%;">
<button>Hi</button>
</div>
</div>

HTML-CSS div is 3px taller than child

I'm working on a project that uses several divs of the same class, each containing a single child element that might be an image or an iframe, of unspecified height. I'd like the container div to be exactly the height of its child element, but the default height is 3px taller than the child.
I've got a JSfiddle demonstrating the problem at http://jsfiddle.net/52me041n/2/.
HTML:
<div class="outside">
<img class="inside" id="pic" src="https://images.duckduckgo.com/iu/?u=http%3A%2F%2Fblogs.cisco.com%2Fwp-content%2Fuploads%2Fclouds.png&f=1" height="200px"/>
</div>
<br/>
<div class="outside">
<iframe class="inside" width="420" height="315" src="//www.youtube.com/embed/VwTnyRHEZSQ" frameborder="0" allowfullscreen></iframe>
</div>
CSS:
.outside{
background-color: red;
}
I'd like to know whether it's possible to set the div to the proper height with just CSS, and if not, how to right it with JS.

Updated the fiddle. http://jsfiddle.net/52me041n/3/
Use -
img, iframe {
display: block;
}

You need to set the display property to block for children inside the parent div. As a practice, I always also set margins and pads to 0 too. fiddle here
.outside > * {
margin: 0;
padding: 0;
display: block;
}

Images are not on the same baseline as text.
add
vertical-align:bottom;
to your img css
fiddle

For "I'd like to know whether it's possible to set the div to the proper height with just CSS, and if not, how to right it with JS." <== Yes,
<div id="cntr"> </div>
css :
#cntr { width : 100px; height : 100px; overflow : hidden; } /* overflow may have other values also like hidden, auto, scroll
*/

Try this code. Fiddle
.outside
{
background-color: red;
display: block;
}
.outside img, iframe {
float: left;
}

Form element container heights

I'm building a form manager for my framework and want to add methods to create form elements based on parameters passed. Each "element container" has the following:
A validation row positioned at the top of the container. This row is turned off by default (display: none) and will only show if a javascript validation error occured.
A label container (situated on the left)
A form control container (situated on the right)
Here is a sample HTML:
<div class='control_container'>
<div class='validation'></div>
<div class='label_container'>
<label for=''>Label</label>
</div>
<div class='elements_container'>
<div class='element'>
<input type='text' name='' value='' />
</div>
</div>
</div>
My issue here is that I need to the control_container to seperate label and elements containers but also need the label_container and element_container to both have the same height irrespective of the content. These 2 containers may have different background colours so I need to ensure that the stretch to the bottom of the control_container and also keep in consideration that the validation div might show (so using position: absolute and top: 0 might not work).
I have tried the following:
Giving control_container a relative position and the 2 seperate containers both a position absolute. As the height of the containers would mostly be dictated by the height of the label (if the label is multiple lines or if the element_container has multiple elements within it this option does not work.
Floats (There I say more? :D)
I would prefer a CSS solution which is compatible with most browsers (including IE8 (am I pushing it to ask for IE7 haha)
Any ideas?
** ADDITIONAL INFORMATION **
I want the layout to look something like this:
--------------------- control_container ---------------------
[Potential validation message (this will be toggled on/off) ]
[label_container][ elements_container ]
------------------- end of control_container ----------------
So label_container (with the label) and elements_container (with it's elements) will be next to eachother. These 2 containers may have different background colours so they should both stretch (height) according to the biggest element. The only issue I see here is validation element which wont show by default so using absolute positioning might not work as the validation message might take the top area and have the elements overlap eachother.

HTML:
<div class="controls">
<div class="message">Test</div>
<div class="label_container">
<label for="">Label Label Label Label Label Label Label Label Label Label Label Label Label Label Label Label </label>
</div>
<div class="elements_container">
<div class="element">
<input type="text" name="test" value="" />
</div>
</div>
</div>
CSS:
.controls {
position: relative;
display: table;
width: 100%;
}
.controls .message {
background: red;
padding: 5px;
color: #FFF;
font-weight: bold;
height: 30px;
width: 100%;
display: table-caption;
box-sizing: border-box;
}
.controls .label_container {
display: table-cell;
background: #D3D3D3;
width: 150px;
height: 100%;
margin-top: 30px;
}
.controls .elements_container {
display: table-cell;
background: #A2A7DD;
color: #000;
width: 650px;
height: 100%;
margin-top: 30px;
margin-left: 150px;
}

How do I make a <hr /> tag go vertically

How do I make a <hr /> tag go vertically, instead of its standard appearance as a horizontal line/going sideways?
I'd like to be able to use this on a mobile site, so a more widely-supported solution is preferable to one that only works in the latest browsers.

This will require changes to more than just the hr. the element above and below it must be floated. the effect can be achieved with a solid border:
<div class="section1"> content </div>
<div class="section2"> more content </div>
CSS:
.section1 {
float: left;
width: 200px;
border-right: 1px solid #333;
}
.section2 {
float: left;
width: 200px;
}
Edit: see also this answer

You could use css transforms. However, this just turns it, things are still where they would be if you hadn't rotated it.
HTML
<hr/>
<hr class="vert" />
<hr id="vert1" />
CSS
/*All <hr>*/
hr {
transform:rotate(90deg);
-ms-transform:rotate(90deg);
/* IE 9 */
-webkit-transform:rotate(90deg);
/* Safari and Chrome */
}
/*<hr> of class ".vert"*/
hr.vert {
transform:rotate(90deg);
-ms-transform:rotate(90deg);
-webkit-transform:rotate(90deg);
}
/*<hr> with id "vert1"*/
hr#vert1 {
transform:rotate(90deg);
-ms-transform:rotate(90deg);
-webkit-transform:rotate(90deg);
}

Well you could possibly make a div (<div></div>) and then give it values with css later regarding height/width. If you want it to apply to one specific object give it an id <div id=""> and more than one object give it a class <div class="">
An example of the css you'd do is:
#(id name) or div.(class name) {
height: ; (how tall)
width: ; (how wide you want it)
background-color: ; (sets the color of the bar)
position: ; (depends on if you want it absolute or static etc.) }
You can obviously add/remove other css as you go depending on what you want to do

Put it in a div:
<div style="border-right:1px solid #333;">
Content here
</div>
This is with inline css. Otherwise, separate the css:
div {
border-right:1px solid #333;
}

I suppose you could re-style <hr /> as an inline-block element, with specified height...
hr {
display: inline-block;
width: 2px;
height: 256px;
}
That's just a basic example to get the <hr /> to look like I think you want it to look. You'd have to play with height and width (and possibly positioning) to make it do exactly what you need...

"float" a DIV to bottom of parent DIV not working. (Using Pos: rel, Bottom 0 etc)

Trying to get a DIV to "float" to the bottom of the div its in. I've got the position set to relative on the parent div and kid, and bottom to 0 on the kid; but it still just sits at the top in the middle.
Parent DIV:
.detailsContainer
{
width: 100%;
height: 30%;
overflow: hidden;
position: relative;
background-color: blue;
}
Kid DIV
.obutton
{
text-align: center;
font-weight: bold;
width: 80%;
height: 29px;
background:rgba(204,204,204,0);
position:relative;
bottom: 0;
display: inline-block;
color: #666;
}
Current actual setup:
<div class="detailsContainer">
<a href="javascript:unhide(\'BookDetails'.$row->BookID.'\');">
<div class="detailview"><b>Book Details<br></a></div>
<div id="BookDetails'.$row->BookID.'" class="hidden">
<table>
<tr><td>Total Stock </td><td>'.$row->TotalStock.'</td>
<td>Current Stock</td><td>'.$row->CurrentStock.'</td></tr>
<tr><td>Awards </td><td>'.$row->Awards.'</td>
<td>Film</td><td>'.$row->Film.'</td></tr>
</table>
</div>
';?>
<br><center><a href = "javascript:void(0)"
onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style.display='block'">
<div class= "obutton feature2">Reserve Book</div></a></center>
<div id="light2" class="white_content"></div>
<div id="fade" class="black_overlay"></div>
</div>
Its kind of a lot to post for this, but want to make sure nothing is interfering that you guys might spot. It jumps out of php near the bottom, I'll post the entire article if you think the issue might be else where.
I tried to make a jsfiddle of it, but there is so much php and variables that by time I gutted it, it'd just be 2 normal divs, having lost its uniqueness and the issue will probably have been deleted.
Thanks -Tom

.obutton position needs to be absolute... for bottom to work the way you're intending.
