How to change the font, style and colour of tag line

What have you tried? I was able to change the characteristics of the text “A single search engine for updates in oculoplastics, ocular oncology, ophthalmic pathology & facial aesthetics.” with this code:

.site-description {
	font-family: Times;
	color: black;
	font-size: 24px;
}

You should enter this code in your theme’s custom CSS option, if one exists, or a custom CSS plugin.

Got it. Thanks a lot Stephen.

Now how do i do the align them. I want the Website title to be at the extreme left and the Tag line to begin a little later. I also want to reduce the spacing between the Title and the tag line

Try something like this:

#header .pad {
	padding-left: 0;
}

.site-description {
	margin-top: -30px;
}

You can experiment with the values until it looks right to you.

It worked. Thanks again.

The pages I have created or the posts have a while background. It does not show up well on the orange and light green background of my site page. How to I change the colour of these pages?

.content {
	background: orange;
}

.page-title {
	background: orange;
	border-bottom: orange;
}
