Words running together is NOT caused by errors in the CSS; rather it's error in the (x)HTML coding.
For instance, here is an example from a LIBRARY book that has never seen Kobo.
Code:
<p class="p">“But you’d die. And me too. And everybody on the planet. You<span class="italic">can’t</span>.”</p>
Note the lack of a space between the
You and the
span.
Code:
span.italic {
font-weight: normal;
font-style: italic;
}
p.p {
line-height: 1.34em;
font-size: 0.92em;
margin-bottom: 0.00em;
margin-top: 0.00em;
text-indent: 1.09em;
margin-right: 0.00em;
margin-left: 0.00em;
text-align: justify;
font-weight: normal;
font-style: normal;
color: rgb(0,0,0);
}
