Besides the much talked about video tag, HTML5 also introduced a couple of new input types, one of which is a rather interesting range input type which basically translates to a slider bar control:
The range input type is currently supported by the latest versions of Safari, Chrome and Opera while other browsers such as Firefox simply treat the field as a textbox.
There are four available attributes – min, max, step and value. min and max should be self explanatory, step determines the size of each increment/decrement and value is the current value of the slider and also determines the placement of the slider when the element is loaded (if not specified, the slider will appear at the centre of the control when it’s first loaded):
<input type="range" min="0" max="200" step="5"></input>
<input type="range" min="0" max="200" value="0" step="5"></input>
I talked about the new border radius property being introduced in CSS3 in my previous blog post, and with a little JQuery I’ve put together a quick demo here of how a 400px by 400px square looks as the border radius changes.
