I want to increase the font size in a message box. I am using this which works with the HTML coding but not sure what to add to select the font I want to use.  
system.gui.messageBox(‘CRITERIA TEXT CHARACTERS \> 400,   
REDUCE SIZE TO SAVE’)

The [font html tag](https://www.w3schools.com/HTML/tryit.asp?filename=tryhtml_font) can help here:

```python
system.gui.messageBox('<html><font size="4"> CRITERIA TEXT CHARACTERS > 400,<br><font size="5">REDUCE SIZE TO SAVE')TO SAVE')

```

Thanks, I was also able to find this in Ignition. Great for bolding and size (h) height I suppose.

The `<h*>` tags are known as heading tags. There are 6 different sizes where `<h1>` would be the heading with most significance and `<h6>` would be the heading with least significance.

You can also use `<b>` tags for bolding text.
