Hi MorrisMuseum,
1. You can remove the sidebar with a little bit of css modification.
Try adding the following CSS to your Quick CSS (located under the Styling Tab in the theme options) or the custom.css file in the css folder of your theme files:
#top.single-portfolio .grid9 {
width: 894;
}
#top.single-portfolio .sidebar {
display: none;
}
2. Add the following css to the same place you added in #1:
#footer p {
font-size: 15px !important;
}
You may need to also target the #footer header elements. If you do (or have other specific font sizes) we can help you target them specifically.
3. In the main style.css file, look for and modify the following:
body {
font-size: 13px;
font-family: Arial, Helevtica, Verdana, san-serif;
line-height: 1.7em;
}
4. How do I add additional social icons to the site; upper right & bottom right?
Open up header.php and look for:
<li class='rss'><a href="<?php bloginfo('rss2_url'); ?>">RSS</a></li>
Right under that, add a new line for each icon and model it after this:
<li class='socialsite'><a href='http://www.socialsitename.com'>Social Site</a></li>
Now add the following css:
.social_bookmarks .socialsite a{background: transparent url(youricon.png) 0 0 no-repeat;}
Replace "socialsite" with the name you put above and the youricon.png should be the URL to where your icon file is located. If you want to put the images in the same folder as the skin you are using, it would look like:
url(../images/skin1/youricon.png)
5. When you add an image into your page with the visual editor, select the image again and hit the Edit image icon. Under advanced settings, you can vertical and horizontal space.
Let us know if you need anything else!
