Uneven Line Spacing

You themes stylesheet at http://www.moritzvs.com/wp-content/themes/novelty/style.css has the following css:

.wpcf7-form input[type="text"] {
max-width: 300px;
width: 60%;
}

You would also need something similar for .wpcf7-form input[type=”email”] as well, if you want all the input boxes to be the same width in all browsers.

Use Firebug or Chrome Dev Tools to see what is happening and fix it.
