font size

how do you adjust font size?

You can’t.

By zooming in/out, typically ctrl&(+ or-)

You can force it in firefox by pressing f12 and search for the html font-size in the css tab (2nd of the left). There you can change it for the time the browser is open. But it is ill advised to do so. It will break the layout of lichess.

1. Install the browser extension "Stylus".

2. Go to lichess, and click on the Stylus icon. A box opens, and there you click "Write style for lichess.org".

3. This opens a new tab with a code editor. Add the following code in that editor:

body
{
font-size: 13px !important;
}
.rclock > *
{ /* Less obtrusive clock */
font-size: 26px !important;
}
inline, comment
{
font-size: 13px !important;
}
textarea
{ /* size/line-height font-family */
font: 14px/1.3 Consolas !important;
}
.study-name /* List under /study */
{
font-size: 1.2em !important;
}

You can of course adjust the sizes to anything you like.

4. Click "Save" in the upper left.

That's all. :)
