What and Why?
</header>
<div class="content">
<p>
As the web progress into a modular component based design, custom elements/web components become
inseparable part of it.
Many libraries and frameworks offer very strong wrappers around this technology to ease and simplify
the
process.
<br>
<br>
This project implement the same custom element with every framework/library, showing the differences.
I tried to polyfill at the top level(this page) for every possible scenario.
Every card hold some benchmark information about the custom element and the Placeholdered image created
with that library/framework.

Future Tasks
</header>
<p>
<ul>
<li>Add unit testing for each element.</li>
<li>Create elements with other frameworks/lib's (react might be a good place to start)</li>
<li>Enhance the build process and webpack configuration.</li>
</ul>
</p>
<header>Contributing </header>
<p>
Each element is built in a seperate package inside the `packages` with his own build/test/dev scripts that
can be found in the package.json file.
<br>
At the root level there is a script that run all the build scripts and collect all the bundled element
files to import them at the index.html scripts array at the end of the file.
<br>
Adding new elements is the best way to contribute to the project and ofcourse improving existing code (eg.
trying to make a bundled file from stencil because at the moment it exports an entire folder).
