Header text adjustment

I know this is simple, but how do I get the header title equal distance between top and bottom?

I tried to add more to top margin, but that didn't move it down.

First of all add
*{
margin:0;
padding:0;
} in to your CSS to remove all default margins and paddings(this will help you to get a uniform layout in all browser by setting specific values).
then add padding-top:40px or some equivalent to header h1.

Thanks, that works! http://www.nwparkingcontrol.com

How would I add extra white space between text and image to make the site taller?
I've tried using [<p>&nbsp;&nbsp;&nbsp;</p>] and I don't think that works very well. I tried adding padding to the img style and that didn't work. Maybe I wrote it wrong.

This can be achieved by adding margin-top/margin-bottom wherever required.

Thanks again. I added margins to the image. How do you add margins to a paragraph of text? [<p>text</p>]

Also: what's the style to center all the text and image?

Have a look at http://www.w3schools.com/css/css_reference.asp
p{
margin-left:auto;
margin-right:auto;
}

OK, I did that, but why isn't there a space between the h4 tags, h3 tagsand the first p tags?

The answer is in my first post.
In order to get gaps between elements, you have to explicitly specify how much you want.

Wow, so the styles override the the normal spaces between h and p tags?
