Create home and login template

  1. Create the files you want to use.

    1. Edit ems_home.html. This can be as simple as a couple of lines of HTML, for example:

      <h1>Snow Leopard LTD</h1>
<h2>Rooms to join</h2>
<ul>
    <li><a href='/#/room/#welcome:snowleopard-staging.ems.host'>Welcome to Demo web chat (#welcome)</a></li>
    <li><a href='/#/room/#support:snowleopard-staging.ems.host'>Support (#support)</a></li>
    <li><a href='/#/room/#offtopic:snowleopard-staging.ems.host'>Off topic conversation (#offtopic)</a></li>
</ul>

      You can also add a more complex HTML and styling.

    2. It looks like this in your web browser:

    3. Edit ems_welcome.html. This is a bit more complex, but it can be almost anything you want as long as it has links to Log in (/#/login) and Create account (/#/register). The default design is based on this template. You can get creative with the CSS and the !important tag.

      The only change I made from the template is adding <p>This is some demo text!</p> on line 177.

    4. It looks like this in your web browser:

Serve the files

You can either serve the files on your own web server or upload them to your EMS Matrix server.

If you host the files on your web server, you need to enable the CORS header Access-Control-Allow-Origin: * on the web server for these files. See https://enable-cors.org/ for instructions on how to do this.

Serve files from your EMS Matrix server server

This is optional. See below for how to configure your EMS server.

  1. Upload the files to an unencrypted room on your EMS server.

  2. Get the ID for all four files. Click the Options button on the message containing the file, then View Source. Copy the url excluding mxc://. Make sure you do not use the thumbnail_url for images.


Configure your EMS server

  1. Add the URLs to the Client look & feel section in the EMS Control Panel. Click Save.

    Unfortunately, we have a bug in the validator affecting files hosted on Matrix. Just ignore the error.

    • Note if you are hosting the files on your own web server, you only need to change your EMS server configuration or reprovision if the URLs have changed. Changes to the contents of existing files are applied automatically

  2. Once your host finishes reprovisioning, check your Element Web to ensure the changes are applied correctly.
