Sounds like you want to format them as inline. By default, h1 and h2 are block-level elements which span the entire width of the line. You can change them to inline with css like this:

h1, h2 {
    display: inline;
}

Here’s an article that explains the difference between block and inline in more detail: http://www.webdesignfromscratch.com/html-css/css-block-and-inline/

To maintain vertical padding, use inline-block, like this:

h1, h2 {
    display: inline-block;
}
