I'm looking for help on why my CSS isn't working.
I want to use the Stylebot chrome extension with this CSS to make gridlines darker on a Google Sheet.
.waffle td, .grid-fixed-table td {
border: 1px solid;
border-color: black;
border-collapse: collapse;
}
The gridlines show for a second when loading a new sheet but then disappear. Can anyone help me to understand why/show me a solution?
