Debugger view hard to read in Chrome & Edge Windows 10

[qurm]

Hi - I find that the debugger view is really hard to read, using current Chrome & Edge browsers (Edge Version 91.0.864.64 (Official build) (64-bit)) in Windows 10. I tested on a couple of Windows PCs with different browsers, so I don't think this is a local problem. The cause is black text on grey in the disassembly and a black on dark red in the register list. I can see there was a "change to Bootstrap 5" on the css files a few weeks back?

I can try to fix the css, and do a PR?
These classes:
<span class="disassembly">BVS $<span class="instr_instr_ref">e461</span></span>
<div><span class="register">A</span>: <span id="cpu6502_a">00</span></div>

Thanks! I don't know why those are so dark; I did try and fix some things but didn't spot them being that dark! PRs always welcome, it should be a quick CSS fix.
