Centering and integrating image gallery - html

Question

HTML/CSS newbie question for you.
I've been stuck on this for awhile. I'm looking to center my image gallery AND also make the padding between the images tighter. I'm thinking I need a container but, I've just been screwing it all up when I try. Any help would be great!
<div id="container" align="center">
<div class="img">
<a href="#">
<img src="#" alt="PIcture1" width="210" height="180">
</a>
<div class="desc">BLAH</div>
</div>
<div class="img">
<a href="#">
<img src="Images/9700_1915630577543_1314909545_n.jpg" alt="oldman" width="210" height="180">
</a>
<div class="desc">BLAH</div>
</div>
<div class="img">
<a href="#">
<img src="#" alt="Picture3" width="210" height="180">
</a>
<div class="desc">BLAH</div>
</div>
<div class="img">
<a href="#">
<img src="#" alt="Picture4" width="210" height="180">
</a>
<div class="desc">BLAH</div>
</div>
</div>
CSS:
#container{
}
div.img
{
margin:5px;
padding: 5px;
border:none;
height:auto;
width:auto;
float:left;
text-align:center;
}
div.img img
{
display:inline;
margin:5px;
border:none;
}
div.img a:hover img
{
border:none;
}
div.desc
{
text-align:center;
font-weight:normal;
width:120px;
margin:5px;
}

Answer 1

It depends on how you want to centre your gallery.
There's a few things that you need to bear in mind. In order to centralise some HTML you need to have a set width of the centralising element.
Here's some code for you to work with:
Create a "centre" class in CSS as follows:
div.centre{
margin:0px auto;
width:800px;
}
Then add it to your container as follows:
<div id="container" class="centre">
The secret to centralisation is in the margin:0px auto;, this is convention of modern web development to centralise content.
Have a look at this code
p.s. don't use align="center" it is depreciated in later versions of HTML. Better to not get into the habit of using it and stick to using CSS classes to centralising things for you.

Answer 2

You should not use align. It is a deprecated property. To center something with a container you need to specify a fixed width and add margin auto.
Ex:
#container {
width:970px;
margin: 0 auto;
}
You can remove the padding on div.img
