How to Install HTML5-Chat in WordPress

HTML5-Chat gives you a script like this:

You can paste this inside:

Gutenberg HTML block
Elementor HTML widget

That’s it. The chat is online.

How to Embed HTML5-Chat Inside a Specific DIV

If you want the chat inside a block with a fixed size:

<div style="width:800px;height:800px;">
<script src='https://html5-chat.com/script/1/56c5dfd75c71c'></script>
</div>

Customize width and height:

Just change the values:

<div style="width:600px;height:400px;">
<script src='https://html5-chat.com/script/1/56c5dfd75c71c'></script>
</div>

Or make it responsive:

<div style="width:100%;height:600px;">
<script src='https://html5-chat.com/script/1/56c5dfd75c71c'></script>
</div>

How to Display HTML5-Chat in Full Screen Mode

Sometimes you want the chat to cover the entire page and behave like a standalone application. Use this example:

<div style="position:fixed; top:0; left:0; width:100%; height:100%; margin:0; padding:0; z-index:9999; ">
<script src='https://html5-chat.com/script/1/56c5dfd75c71c'></script>
</div>

Now your page becomes a full-screen chat interface, ideal for:

Live streaming
Chat rooms
Full page messaging
Fullscreen support & mobile-friendly display

How to Make the Chat Responsive

For a layout that automatically stretches to the screen size:

<div style="width:100%;height:100vh;">
<script src='https://html5-chat.com/script/1/56c5dfd75c71c'></script>
</div>

✔ 100vh = 100% of viewport height
✔ Works on mobile, tablet and desktop

Advanced customization examples

Add a border and rounded corners:

<div style=" width:800px; height:600px; border:2px solid #ccc; border-radius:10px; overflow:hidden; ">
<script src='https://html5-chat.com/script/1/56c5dfd75c71c'></script>
</div>

Center the chat on screen:

<div style=" width:800px; height:600px; margin:0 auto; ">
<script src='https://html5-chat.com/script/1/56c5dfd75c71c'></script>
</div>
