I think you need to be a bit more specific, otherwise no-one will know exactly what parts to explain and to what level!

i just wanted to understand each line in these codes above. i'm new to CSS. i mean i can copy them and put them in my web site but i just wanted to understand each code first. i mean the main things in this "CSS Image Gallery" for example: this code below:


.thumbnail span{ /*CSS for enlarged image*/
position: absolute;
background-color: lightyellow;
padding: 5px;
left: -1000px;
border: 1px dashed gray;
visibility: hidden;
color: black;
text-decoration: none;
}
