Try:
Code:
p{
text-indent:0 !important;
margin-left:0;
margin-right:0;
margin-top:.18em;
margin-bottom:.18em;
font-family:"Times New Roman",serif;
font-size:1em;
letter-spacing:.045em;
}
So, add the !important. I also changed the font-size from 100% to 1em. That way resizing will be nicer.
Be careful, some readers will not like the !important tag, but some reading apps (aldiko, Stanza) will not play nice otherwise.
