Using percentages for height and width for images

Hi,

I have a Bootstrap-3 template and at first I had all my images with this code:

<img src="assets/images/1.jpg" alt="1" width="40%" height="2%" border="0">

That worked perfectly as my images were responsive to all device dimensions.

I then ran a HTML/CSS validator and all images where I used above code came back with error, a respectable 59 errors in total(I use a lot of images in my articles blog... Big smile ).

So why does above code does not validate??? Its sweet, easy, fast and effective.

A zoom-able user interface with CSS?

Hi guys, I've been surfing the internet for the past couple of days to view impressive webpages, and one i'm still mindblown by is: http://2011.beercamp.com/

I really want to recreate my own version of this (with my own text and pics) for fun, but I'm still confused as to how it works even after reading http://2011.beercamp.com/colophon/ .

Can anyone give me a recommended workflow as to how to teach myself advanced CSS and stuff like this? Any input is appreciated. Thanks!! Laughing out loud

Here is the website: http://www.webtoolhub.com/

The inner pages are more complex. What is the best way to go mobile friendly?
