Custom HTML page for Web export
====================================
While Web export templates provide a default HTML page fully capable of launching
the project without any further customization, it may be beneficial to create a custom
HTML page. While the game itself cannot easily be directly controlled from the outside yet,
such page allows to customize the initialization process for the engine.
Some use-cases where customizing the default page is useful include:
- Loading files from a different directory than the page;
- Loading a ``.zip`` file instead of a ``.pck`` file as the main pack;
- Loading the engine from a different directory than the main pack file;
- Adding a click-to-play button so that games can be started in the fullscreen mode;
- Loading some extra files before the engine starts, making them available in
the project file system as soon as possible;
- Passing custom command line arguments, e.g. ``-s`` to start a ``MainLoop`` script.
The default HTML page is available in the Godot Engine repository at
`/misc/dist/html/full-size.html `__
but the following template can be used as a much simpler example:
.. code-block:: html
