# Contributing to this project
Please take a moment to review this document in order to make the contribution
process easy and effective for everyone involved.
## Using the issue tracker
The issue tracker is the preferred channel for [bug reports](#bugs) and
[features requests](#features), but please respect the following restrictions:
* Please **do not** use the issue tracker for personal support requests.
* Please keep the discussion **on topic** and respect the opinions of others.
<a name="bugs"></a>
## Bug reports
A bug is a _demonstrable problem_ that is caused by the code in the repository.
Good bug reports are extremely helpful - thank you!
Guidelines for bug reports:
1. **Use the GitHub issue search** &mdash; check if the issue has already been
reported.
2. **Check if the issue has been fixed** &mdash; try to reproduce it using the
latest branch in the repository.
3. **Isolate the problem** &mdash; create a [reduced test
case](http://css-tricks.com/reduced-test-cases/) and a live example.
A good bug report shouldn't leave others needing to chase you up for more
information. Please try to be as detailed as possible in your report. What is
your environment? What steps will reproduce the issue? What browser(s) and OS
experience the problem? What would you expect to be the outcome? All these
details will help people to fix any potential bugs.
<a name="features"></a>
## Feature requests
Feature requests are welcome. But take a moment to find out whether your idea
fits with the scope and aims of the project. It's up to *you* to make a strong
case to convince the project's developers of the merits of this feature. Please
provide as much detail and context as possible.

mburger CSS
================
A small collection of CSS animated hamburgers. All set up to work out of the box with the mmenu.js plugin.<br />
[Examples](https://www.mmenujs.com/mburger)
<img src="https://mmenujs.com/img/preview-mburger.png" alt="CSS animated hamburgers" width="100%" />
### Customize the hamburger
By default, the hamburger adopts to its environment pretty good,
the bars scale to fit and inherit their color for the parent element.<br />
Need help? Have a look at [the documentation](http://mmenujs.com/mburger) for examples and documentation.
### Licence
The mburger CSS is licensed under the [CC-BY-4.0 license](http://creativecommons.org/licenses/by/4.0/).
### Development
This project uses [Gulp(4)](http://gulpjs.com/) to transpile and minify SCSS to CSS.
If you are unfamiliar with Gulp, check [this tutorial](https://travismaynard.com/writing/getting-started-with-gulp) on how to get started.<br />
Run `gulp watch` in the command-line to put a watch on the files and run all scripts immediately after saving your changes.

<p>A small collection of CSS animated hamburgers.
All set up to work out of the box with the mmenu.js plugin.
Click a hamburger to see the animation.

<h3>Customize the hamburger</h3>
<p>By default, the hamburger adopts to its environment pretty good,
the bars scale to fit and inherit their <code>color</code> for the parent element.</p>
<p>The hamburger is pretty easy to customize too,
just override some of the CSS values and variables.</p>
