In addition, I should mention that because I had issues with so-called assumed "default" values, which did not seemed to contain the assumed default value at all (cannot remember whether it was Kobo / Sony / other), I always include at the top of my CSS the following:
Code:
* {
margin: 0;
padding: 0;
line-height: normal;
}
The "line-height" is very necessary on using the font-family "Bitter Pro" (which is often my standard font), as otherwise the default line-height is annoyingly high.
But as always, YMMV
