Fix tag with color for titles (1.8)

Since the 1.8 update, some tags that I use to mark titles do not work.
The tag “2” is used to mark chapters in blue as you can see in the image, but since the update it doesn’t work until you put the mouse over it (then it is activated).

I don’t know if someone could help me to solve it.

On the other hand, it makes me think that it is better to use the rem.header (for titles, since the tag is more likely to not work after an update.

background: #D8F1FD; /color de fondo del resaltado/

border-top: 2px solid grey;
border-right: 1px solid grey;
border-bottom: 1px solid grey;
text-align: left;
