TEXT FORMATTING

How do I make text thicker in the Opera browser?

And I mean, not just making everything bold. I already managed to do that, the problem is, that the previously bold text keeps being bold and does not get bolder, when I put "font-family: Arial Black" or "font weight: bold" into user css. I want the text to be 'thicker'/'better visible' without losing the distinction of bold text within the viewed document.

Any ideas on how to do this, /comp/?

how about just zoom in?

Aside from the thickness of the text, I don't usually wish for any other components of the document to be upscaled.

preferences (ctrl+f12) - webpages - normal font - select "wide latin" (thick as fuck)
