What?
So this is a quick article to demo how to center an iframe horizontally and vertically in a screen/viewport in pure CSS (no JavaScript allowed). This CSS centers it by its center point rather than the top/bottom/left/right outline.

Why?
On a mobile, a client's site uses an external page embedded by iframe. When the app within the iframe has an alert message, it popups a div at the centre of its app. The alert message is always at the center of the iframe but if the iframe has a height of 2000 pixels, the iframe gets aligned to the top of the parent...

How?
We're going to use a touch of CSS and instead of determining heights and alignment with JS.

What?
A quick article to remind me on how create an multi-level ordered list that indents and aligns correctly.

Why?
I'm finding that I need to do this quite often for some clients who want to include their terms and conditions in quote/invoice templates and want the HTML to be indented neatly.

Other examples out there will work, but I found that once the list count increased the number of digits (eg. 1.10) the text would be more indented (relative) to 1.1. I need all list elements to be all perfectly aligned.

How?
I've been refining this based on several examples and the following solution seems to be the most stable:
Category: Cascading Stylesheets :: Article: 686

What?
This is an article I hope to refine one day where given a set of breadcrumb hyperlinks, when I hover the mouse over the links, the text changes and the transition between the two is controlled smoothly.

Why?
At time of print, I couldn't find any clear example demonstrating this so here's my take on it:

What I have
copyraw
» Home / Products / Lanterns
  1.  » Home / Products / Lanterns 
What I want (on mouseover)
copyraw
// if I hover the mouse over the "Home" link:
» Return to Home / Products / Lanterns        

// if I hover the mouse over the "Products" link:
» Home / More Products / Lanterns        

// if I hover the mouse over the "Lanterns" link:
» Home / Products / More Lanterns
  1.  // if I hover the mouse over the "Home" link: 
  2.  » Return to Home / Products / Lanterns 
  3.   
  4.  // if I hover the mouse over the "Products" link: 
  5.  » Home / More Products / Lanterns 
  6.   
  7.  // if I hover the mouse over the "Lanterns" link: 
  8.  » Home / Products / More Lanterns 

How?
Category: Cascading Stylesheets :: Article: 680

What?
I saw a lot of articles that would cover this but I wanted an example which includes headers and footers and how to get an automatic page-break-inside to not overlap these. Fine on screen but this is obviously for when it comes to printing.

Why?
I needed to create a template in HTML where the first page is a cover page (background image filling the page with a logo floating at the centre) and the next page has a table which is of variable length. Fine when the table was short and didn't have many rows. But the client will pick up the phone to you when the table has too many rows to fit on one page, and this overlaps onto the next, covering the footer and header...

How?
By spending a lot of time spinning on my chair and twiddling my thumbs...

  • CSS
  • HTML
What?
A quick article on how to get a div layer to increase height based on how a heading fits on a page.

What?
I have a heading like this:
The heading in full width
The code of this is:
copyraw
<div id="page-title" class="col-xs-12">
	<h1><a href="/">A long heading that wraps over several lines</a></h1>
</div>
  1.  <div id="page-title" class="col-xs-12"> 
  2.      <h1><a href="/">A long heading that wraps over several lines</a></h1> 
  3.  </div> 
Category: Cascading Stylesheets :: Article: 646

What?
So many people asking this when the solution is a bit of aesthetic styling.
copyraw
ol{margin:4px}

-- yields
995.
996.
997.
998.
999.
000.      <-- What's going on here then?
001.
002.
  1.  ol{margin:4px} 
  2.   
  3.  -- yields 
  4.  995
  5.  996
  6.  997
  7.  998
  8.  999
  9.  000.      <-- What's going on here then? 
  10.  001
  11.  002

Ordered List Issue

How?
Category: Cascading Stylesheets :: Article: 485

What?
So this is an article to note an oddity when I was working with a Yootheme template called "yoo_sync". Some clever scripts (both mootools and jquery) using the equalize method to make div layers the same height, and in this case, the same width. It isn't so much a miscalculation of 100% divided by 3 that leaves 1 pixel left over, more the fact that the scripts use that 1 pixel (ceiling rather than floor?).

Why?
We have a row on a website of three boxes made of div layers. When viewed normally on a 15" Laptop, all was good using Chrome and tolerable using MS Internet Explorer. If we maximized the Google Chrome browser, the row would split and there would be 2 boxes on the top row and the third would pop under these. As for MSIE, that was ok when maximized.

How?
You could do loads of code hacks which is what I tested but all for nothing because you always end up needing to specify a third of the width.

What?
This is a quick article on how to resolve the following issue:
  • Overall body background color is blue.
  • Background color of my contents is white.
  • When I visit a small page on the site, the contents background (white) shows.
  • When I visit a very long page on the site, the contents background disappears and reveals the overall background (blue) making the text very hard to read.

Why?
Took me a while to figure out what was the problem, I'd visit some pages and they'd be fine, but when visiting a long page, it would initially display properly but then the white background would disappear when the page finally loaded.

How?
