Got your url via email, thank you.
Ok, so if you want to change all of the body fonts, look at line 130 of styles.css:
body {
margin: 0;
font-family: 'Open Sans', sans-serif;
font-size: 13px;
line-height: 19px;
color: gray;
background-color: #fafafa;
}
For the entry-text and comment headings, look at line 2498
.entry-text h1, .entry-text h2, .entry-text h3, .entry-text h4, .entry-text h5, .entry-text h6,
.comment-content h1, .comment-content h2, .comment-content h3, .comment-content h4, .comment-content h5, .comment-content h6
{
margin: 15px 0 15px;
font-family: "Fjalla One", sans-serif;
font-weight: normal;
-webkit-font-smoothing: antialiased;
}
And for your widget titles (sidebar), line 2674
.widget-title {
font-size: 16px;
text-transform: uppercase;
font-family: "Fjalla One", sans-serif;
font-weight: normal;
margin-bottom: 5px;
-webkit-font-smoothing: antialiased;
color:#aaa;
}
If you take any of these blocks and paste them into your Child Theme style.css file, you can change all of the attributes as you wish.
No idea on the slider/map question, sorry!
