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>
