Ok. Changing margin-top on the footer worked for me again. I'm guessing it's because you didn't provide your full CSS code. I'd recommend just giving us a link to your site. Lol.
This also wasn't what you wanted, but I'm going to recommend making a some changes...to get you started in the right direction.
Your code starts out like this:
You are only supposed to have one body. In addition to that, start using CSS to give your body a background. Something like...
Next, the center tag has been deprecated since HTML4. So, instead of something like this:
You should give your image a CSS class and style it with CSS like this:
<center><img title="London" alt="London" src="Pinto/images/London.jpg"></center>
<img class="centered-image" title="London" alt="London" src="Pinto/images/London.jpg">
Think of HTML as the skeleton or the content. CSS is the design. If you want to make changes in the design, adjust the placement, change the width, or just do anything like that, you use CSS.
Also, there is this section:
You open up a paragraph tag and then a heading 3 tag. That's odd. You should use one or the other. Then, before you even closed h3, you closed p. General rule: You close the nearest tag first.

You're also using a ton of linebreaks. I can understand using them once in a while, but once again, you should stick with CSS.
