CSS - Can Someone Explain This To Me...
Can someone explain to me how between this html and this css that this site determines the position of each of the divisions?
I'm not seeing how exactly it is interpreting the code to display the header and then move down to the next row, then display the left sidebar and the content and then move to the next row, then display the footer. How is this being done? I hope that makes sense. I'm starting to grasp alot of the CSS but I'm still not seeing how it is continuing on down from one division/frame to the next row and then displaying 2 divisions/frames and then moving to the next, and I think once I get this concept I'll be set.

Is it merely reaching the end of the width as is determined by the expression in the #page-wrap width statement and then moving to the next line using the margins determined in the #page-wrap #inside? Thanks for the help! Similar TutorialsHi i'm using the html below, for some reason in Dreamweaver the two images in the two lower cells appear on the left, and the text on the top button is up the top of the table cell. Is my code creating a conflict somewhere that would cause this? When I open it in Firefox or IE it looks fine, its just looking weird in design mode.

Cheers, Mark link There's something odd going on with the first quote box div and h2 that I can't quite work out, it doesn't appear to happen to subsequent divs (even though they're just copied and pasted...) Any ideas what could be causing that and how to fix it? Thanks --James Hello! I have been teaching myself the ins & outs of CSS for presentation & there is something I'm not exactly clear about "selectors, classes, ids, rules & definitions, delimiters" and the like. Sometimes I notice people are creating rules for elements or classes that look very different...I think this has to do with parent elements or selectors/properties, but I am not sure. Here's a few examples of rules that I don't understand: Code: div#navigation #navigation .navigation a .body div#navigation > a I know how to define a rule & class, for example #navbar to set the properties such as text color, background, etc. even a background image for this DIV. What I'm trying to say is "What the heck is the difference between using a Hash mark (#) versus a period (.) and when the heck did > or < come into play?" No tutorials on learning CSS seemed to actually explain these, just tell you "that's how it is," so I am very curious to learn more. Thanks for your help! Hi .. I have decided to teach myself Web Development .. and I have jumped into HTML and CSS first .. and will be branching off to PHP once I have a solid HTML and CSS foundation .. To teach myself practically .. I have decided to make a webpage that does nothing but have a blank coloured background and an area to write text that is surrounded by a rounded rectangle constructed of gifs .. I know this may not be the most efficient way to do this, but I am using this as an exercise to gain a greater holistic understanding of the way CSS works with HTML. The desired outcome is to have a rounded rectangle box that will be drawn to fit its container, so that it can be reused all over the place ... The code is pasted below, and any images can be substituted for the ones in my code .. but my question is .. : in the attached code, why is the final element not lined up horizontally with the other 2 elements ?? <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "(*********)"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <link href="styles.css" rel="stylesheet" type="text/css"> <title>Insert title here</title> </head> <body> <div id="body"> <div id="container"> <div id="box_top_left"> </div> <div id="box_top"> </div> <div id="box_top_right"> </div> </div> </div> </body> </html> CSS Code div#container{ width: 500px; height : 500px; position:absolute; background:#7868723; } div#box_top_left{ width: 10px; height: 10px; display: block; float:left; background-repeat: no-repeat; background-image: ******* } div#box_top_right{ width: 16px; height: 10px; float: right; position: relative; display: block; top: 0px; background-repeat: no-repeat; background-image: ******** } div#box_top{ width: 100% - 26px; height: 10px; display:block; position:relative; left : -5px; margin:0; background-repeat: repeat-x; background-image: ******* } Thanks for any assistance you can give ... So what exactly is vertical-align for, if it doesn't do this? Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <body style='color:white;'> <div style='display:block; height:600px; background-color:orange; vertical-align:middle;'> <div style='position:absolute; display:block; height:50%; width:75%; background-color:green; vertical-align:middle; text-align:center;'> <span style='position:absolute; display:block; line-height:100%; vertical-align:middle;'>Please Center me</span> </div> </div> </body> </html> Well, I know CSS however I am a bit confused with fixed width and liquid layouts as far as I know fixed width is where you set a divs width in pixels and liquid is in % so it scales to the users screen size? Which one is best to use? Also, I have the following style sheet which I created, I am guessing this is a liquid layout? Code: * {
margin: 0;
padding: 0;
}
body {
font-size: 15px;
background-color: black;
color: white;
}
#header {
width: 100%;
margin-bottom: 10px;
border-bottom: 1px solid white;
}
#header h1 {
padding-left: 25px;
margin-bottom: 0px;
}
#content {
padding: 10px;
margin-left: 200px;
border-left: 1px solid white;
}
#content h1, h2, h3, h4, h5, h6 {
text-align: center;
}
#nav {
float: left;
padding: 10px;
padding-left: 15px;
width: 20%;
}
#nav li {
list-style-type: none;
}
#nav a {
text-decoration: none;
}
#footer {
clear: left;
border-top: 1px solid white;
margin-top: 10px;
margin-bottom: 10px;
border-bottom: 1px solid white;
width: 100%;
}
a {
color: silver;
text-decoration: underline;
}
a:hover, a:focus {
font-weight: bold;
}
a:visited {
font-style: italic;
}
h1, h2, h3, h4, h5, h6 {
margin: 10px;
}
p {
margin: 5px;
}
select {
width: 30%;
}
textarea {
width: 40%;
}
.floatimage {
float: left;
margin: 10px;
}
