How do I change the text font in my header

This is a tiny css change. Go to appearance –> editor and then find stylesheet (style.css) According to firebug it should be line 90.

h1 {
    font: 45px arial;
    text-align: center;
}

The h1 refers to “heading 1” which means it’s the biggest and most prominent for SEO.

Thank you. I will try that. I figured that if I knew what it was it would be a quick fix.

Sure! Let me know if it works out for you.

It didnt work. Will you tell me what to change? Here is the stylesheet:

I don’t see the change in that css but it’s really hard to get a good overview.

thanks for your help

It looks as though the text

Lucid Dreaming Techniques

is currently displaying in the Arial font.

Are you trying to also change the tagline?

Lucid Dreaming Techniques Revealed

I was trying to change it to arial. I thought arial looked different. Maybe I was thinking of courier. I wanted something that was more smooth. So, you answered my question. I guess I have it figured out. Now I just have to find the right font. Thank you.
