Frequently asked questions
Where do I paste this CSS?
In Streamlabs or StreamElements, open your Chat Box widget settings and find the Custom CSS box (often under an Advanced or HTML/CSS section). Paste the generated CSS there and save.
Will it work with my chat widget?
The CSS targets the common chat-widget selectors used by Streamlabs and StreamElements. If your widget uses different class names, you may need to adjust the selectors, but the styles are a solid starting point.
Why turn on the text outline?
A text outline keeps chat readable when it sits over bright or busy gameplay. It adds a thin dark edge around the text so it stays legible on any background.
