burgerlicious

Yummy! Burgerlicious is the animated burger icon you always wanted.
SVG-based, customizable via SASS, dependency-free.

What it does

Some love it, some hate it: The burger icon, a three-lined icon synbolising a navigatable list. Why its Usability is debatable, it's for sure a neat and clean way to hide the bigger kind of menus behind a simple button.

So, if you're searching for a beautifully animated burger icon based on SVG and SASS - you're there, you got it! Have fun!

Browser compatibility:
Due to the IE not being able to animate SVG via CSS, animations won't work in this browser! Progressive Enhancement at its best!

How to use

Using this burger means simple copy-pasting code into your project (mainly because including HTML files in the frontend, without backend / build steps, is quite a pain). The following files exist:

• src/burgerlicious.html contains the HTML part, in particiular the burger icon as SVG
• src/burgerlicious.scss contains the styles as SASS, incl. variables & animations

This project also comes with a build step (npm run build) to turn the SASS into plain CSS.

Once included, you can toggle the burger on and off using the is-open class on the svg (with the class burgerlicious).

Customization

The following SASS variables can be used to customize the design of the burger:

• $burgerlicious--color defines the line color (defaults to #333)
• $burgerlicious--weight defines the line stroke width (preferably even numbers) (defaults to 2px)
• $burgerlicious--animation-speed defines the complete animation duration (defaults to .5s)
• $burgerlicious--animation-rotation defines the animation rotation direction (left or right) (defaults to right)

On Usability & Accessibility

Both usability and accessibility of the burger menu could be improved by:

• placing the burger inside an actual <button type="button"> node
• making the burger button more affordable
• adding a short label such as "Menu" or "Navigation" below or above the burger icon
• putting a tooltip on top of the icon (e.g. using the title attribute)
• adding accessibility nodes to the SVG, such as <title> or desc
• disable animations if the user prefers reduced motion / no motion at all
