Hey, Tannin and welcome to the world of WordPress! 🙂 Well, I would save a backup of your style.css file before editing it. You can do that with FTP.
Next, to edit your style.css, in the Dashboard find the “appearance” menu on the left. Click on the “Editor” link within that menu.
When the editor loads, you will will need to make sure you are editing the Twenty-ten theme (check the drop-down menu at the top right to verify).
Next, you’ll see a list of files on the right, scroll down until you see “Stylesheet (style.css)”. Click it.
When that stylehseet loads in the editor, you will need to find the FONTs section in the styleshet. The code looks like this:
/* =Fonts
-------------------------------------------------------------- */
body,
input,
textarea,
.page-title span,
.pingback a.url {
font-family: Georgia, "Bitstream Charter", serif;
}
h3#comments-title,
h3#reply-title,
#access .menu,
#access div.menu ul,
#cancel-comment-reply-link,
.form-allowed-tags,
#site-info,
#site-title,
#wp-calendar,
.comment-meta,
.comment-body tr th,
.comment-body thead th,
.entry-content label,
.entry-content tr th,
.entry-content thead th,
.entry-meta,
.entry-title,
.entry-utility,
#respond label,
.navigation,
.page-title,
.pingback p,
.reply,
.widget-title,
.wp-caption-text,
input[type=submit]
{
font-family: "Helvetica Neue", Arial, Helvetica, "Nimbus Sans L", sans-serif;
}
pre {
font-family: "Courier 10 Pitch", Courier, monospace;
}
code {
font-family: Monaco, Consolas, "Andale Mono", "DejaVu Sans Mono", monospace;
}
You will need to override the default by declaring a different font value for the site title. Looking at the code, the site title is controlled by the rule: #site-title and #site-info (#site-info is the tagline, the “just another wordpress site” text).
So go ahead and delete those from the list.
Then, at the bottom of the FONTS section in the stylesheet, type the following:
`#site-title: {font-family: Arial, Helvetica, sans-serif;}
#site-info: {font-family: Arial, Helvetica, sans-serif;}’
Of course, change the “Arial, Helvetica…etc” part to whatever font you want to use.
Good luck and let me know if you have any further questions working with this.
Ideally you should be making these changes in a Child Theme, but since you are just getting started, this would be the easiest way.
