```
.highlightgreen {
background-color: lightgreen;
}
```
Do you think it would be safe and is there a plugin that supports it? The methods most people mention don't involve editing the EPUB directly but using external metadata  |
Jumping between a kindle, libra, iBooks and pc when reading really destroyed any hope of reliable highlighting. So I use a similar method using the <mark> tag
<mark>This is some text I need to highlight/annotate
</mark>
My CSS
mark {
background-color: yellow;
}
