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:
<center><img title="London" alt="London" src="Pinto/images/London.jpg"></center>
You should give your image a CSS class and style it with CSS like this:
<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:
<p><h3>Finding a partner in far-away places that can organize the travel arrangements of your clients, or changing an existing one because of poor service or excessive cost, is not always easy and the outcome is often unpredictable.</p>
<p>This website attempts to solve the problem by providing essential information about incoming agencies in every country and region of the world. Besides, by relying on feedback from users (Travel Agencies) the links and information recveived play an important role in maintaining the confidence in those firms that are displayed in these pages.</p> </h3>
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.
