@luismarioochoa:
1. Dots are already there in the center, so you might want to remove this. For that you can add the following css in “Appearance => Theme Options => Custom CSS” box :
#slider-nav { display: none; }
2.a) You can change the font size in the following css and then add it in “Appearance => Theme Options => Custom CSS” box :
#featured-post .entry-title { font-size: 22px; }
2.b) There is nothing like that. But yes, you can manually add hyper link in that content post. For example:
<a href="you-url">Continue Reading →</a>
3. Simply add the following css in “Appearance => Theme Options => Custom CSS” box:
.site { box-shadow: none; }
4. Sorry I don’t get it what you mean.
