Swap Images - Template #422

Media Queries

Media Queries allow the developer to change font sizes, alter navigation devices and resize images or actully swap them out at different screen sizes as this template demonstrates.

To demonstrate grab the right edge of the browser and squeeze it to the left.

As the width of the screen decreases three different size images will be displayed using the Media Queries in the style sheet.

When you've squeezed as far as you can open Developer Tools beside it to get to the smallest size screen width.

You could also use the Device Toolbar provided in most versions of Developer Tools shown here, left of Elements, to emulate various viewing devices.

Drop down Menu

The CSS for the drop down menus is a bit verbose, but it's easier than learning javascript which can slow page performance. There are a lot of sites out there that offer free menu codes, but most are heavy on the JS and will pose problems for beginners when trying to troubleshoot problems that arise.

What was then Liquid web design evolved further into what today is the norm as RWD.
