Improve Vivaldi button states

I find the enabled vs disabled states of the Vivaldi browser's back and forward buttons to be nearly indistinguishable. I couldn't figure out the best way to fix this, so I asked ChatGPT and the answer worked. Here's how to make the states more distinct using CSS./* Disabled Back/Forward buttons more faded */ .button-toolbar button[disabled], .button-toolbar button.disabled { opacity: 0.18 !important; } /* enabled Back/Forward buttons stronger */ .button-toolbar button:not([disabled]):not(.disabled) svg { stroke-width: 2.6px !important; } Open vivaldi://flags/#vivaldi-css-modsEnable Allow CSS modificationsRestartGo to Settings → Appearance → Custom UI ModificationsCreate a CSS file with the above contents and put it in the configured folderRestart Vivaldi againMuch better.
