CSS - Auto-height Property
So, I have a div that is acting as a container. I contains a background image and colour that goes beyond the image should the image not be big enough for certain resolutions. Anyways inside this div container are 2 more divs, one with a set height that holds images, and another one below the first one that holds text. Now this text changes on a regular basis, but I don't really want to have to adjust the height of the container div everytime I add more text or take away text, I want it to automatically adjust the height as it needs to. I tried setting the height property to auto, but that didn't do anything. Just wondering if someone knows a way to do this?
Similar TutorialsHi all, I am trying to automate everything on my test website and I have one more angle to cover. In effect, I want to adjust the line-height property (which I can do) based on the number of files within a specific folder (PHP and already done). The more files in the folder, the lower the line-height value must be. This is to ensure if I copy additional files into the folder, then the navigation menu (which is PHP reading files in this particular folder) will alter the CSS line-height property accordingly to ensure it can never exceed a certain height. Sounds wierd? go to www.re3.org.uk (next to the RE3 image, I have a list of hyperlinks which are obtained from files within the folder) My problem, when adjusting the CSS property (which is set as cm in *.css file) in javascript, it doesn't correspond correctly, the line-height property in javascript doesn't appear to be work in cm but some other measurement. Does anyone know how to change what unit of measurement Javascript works in? Or does anyone know what unit of measurement javascript uses when adjusting line-height / line-width values? I want to create a mini-algorithm that works out the appropriate line-height based on the image height (got that already) and the number of files in the folder (got that too) so the menu automatically adjusts to fit. Whew! Hi, I have recently changed to using a DIV layout when designing sites. One problem i have noticed is that the margin:0 auto; doesn't work in IE5.5 What can I do to get around this? Many Thanks, Jonathan. I am building a custom form control that behaves more or less like a <select> menu. For the dropdown portion of the menu, I need to set a max-height. If the dropdown contains enough options to go beyond the max-height a vertical scrollbar should appear.

I'm seeing some unexpected behaviour ihn Firefox. When the page is loaded for the 1st time, the height of the dropdown portion of the menu is only large enough to see 1 option and no scrollbars are displayed. If I hit refresh (without holding the Shift key), the menu's height goes to its max-height and displays as expected. The only property I could find that has any effect on this behaviour is overflow. If I remove it all together or set it to scroll, it displays at the correct height. Unfortunately, neither of these are an option since they will not produce the desired scrolling behaviour. Can anyone see where I'm going wrong? I am trying to figure out how I can get this red curve to align to the bottom of the page, while also being able to move up and down with the size of the browser window. http://www.woodrichwebworks.com/psa/psa_comps/bycor/html/redtest.html Any help would be great. I am wondering if there is some way to make a <div> layer automatically expand to the full height of the screen similar to the way that one would use width=100% when talking about the width of a page. I have a layer that I want to extend to the bottom of the page no matter what resolution the user has on their screen. Maybe the layer could just extend all the way until the next layer? Any Ideas?

Basically I have a div that fills up the main div(main). The reason that there are 2 other divs is because one is slightly translucent and I didn't want the text to be translucent so it is for sitting on top of it and displaying the text, (I know it doesn't do that right now, this is just example code). My problem is that I want the div(test) to fill up the main div(main) from a certain point down, that is make it start 151px from the top and then expand until the bottom of the main div. I discovered that you can do this in firefox and opera by placing a - at the end of the height:100%. I don't know if this is correct, but it works. It does not work however in ie6. i can chop it using overflow:hidden;, but thats not really the functionality I want since the div in the final version will have a border on it. Is there someway to make it display the same way in Internet Explorer 6 as in firefox? Thanks akurtis Question) In CSS can you line-height be set to a lower value than the current font size? What does this cause? potential answers (practise revision exam are) A) line-height cannot be set to a value lower than the current font size B) The lines are cut to prevent overlapping C) The lines will overlap I am pretty sure they overlap but want to confirm I'm pretty new to this so I'm not 100% sure what I'm doing yet. However, I've created a test page to show you guys the rendering issue that I'm experiencing. The page renders how I want it to in Firefox, Flock and Chrome. It renders incorrectly in IE8 (which is a required browser that this needs to be supported in). Here is a link to the test page cm-rosestate.mine.nu/test.aspx and the css is /MyStyle.css My suspicion is that it's a problem with the css and/or the doctype. However, I just don't know enough about this to know how to troubleshoot it. Any help or insight will be appreciated. Hi guys, Before I go on, here's the page I'm referring to: http://student-consolidation-loans.co.uk/newsite3/ In IE 6 on the PC the layout is how I want it, however, skip over to the mac and it doesn't look correct in any browser (safari, IE, firefox...) The problem is I've given one of the DIVs (the one that contains the white and black diagonally striped background) an auto height so it stretches to fit all the content, but while IE 6 is picking up on this none of the mac browsers are. Is there a workaround? thanks! Hi all, I have come back to designing websites after a long time and I am having problems making the height auto work in firefox. The css code: Code: div.t2_container{
width:679px;
height:auto;
text-align:left;
padding-top:10px;
padding-bottom:10px;
background:#e7e7e9;
}
div.t2_col1{
float: left;
width:470px;
height:auto;
display: inline;
clear:both;
background:#FFFFCC;
}
div.t2_col2{
float: right;
width:199px;
height:auto;
display: inline;
background:#CCFFFF;
}
and the html: Code: <body> <div class="t2_container"> <div class="t2_col1"><p>text text</p><p>text text</p><p>text text</p></div> <div class="t2_col2"><p>text text</p><p>text text</p><p>text text</p><p>text text</p></div> </div> </body> IE recognizes the height = auto on the container div and resizes so that the inner divs are contained within the grey bounding box of the container. However firefox does not recognize this and the 2 inner divs fall outside the container which is left hanging thin at the top. Does anyone know a fix for this pls? Thanx Hello! I'm hoping you guys could help me with a small problem.. I'm trying to get my images to keep their aspect ratio with this CSS, #photo-inner img { margin: 0 0 10px; padding: 0 0 10px; max-width: 718px; width: expression(this.width > 718 ? 718: true); height: auto; } Works perfectly in Firefox, Safari.. But IE don't want to play along. Any tips? // T Hi Guys I am currently trying to make a website, the problem is that its not quite working..... I have a main div that holds everything inside it but when i set its height to auto its not staying the correct length. Basically i want this main div to stretch out longer every time new content is added (dynamically). Why is it not staying as long as the content thats contained within it? Anyone know why this is happening and how i can fix it ? Help?! Code: #main {
height: auto;
width:868px;
margin-left:15px;
margin-top:15px;
background-color:#FFFFFF;
margin-bottom:3px;

Thanks Let me start by saying I'm new to CSS and web developement in general. So I'm probably missing something simple. I have an ASP page that has a treeview along the left, and a tab control to the right of it. I put everything in div's, and floated left the treeview and tab div's. I put a div around it all to have a border. I set that div to be height:auto (or 100%), and it doesn't expand at all. I can give it a true height, but that's not really what I want. Also, it I resize my page really small (manually), the tab div drops below the tree div. Here is the code. Can anyone point me in the right direction to accomplish what I'm trying to do? Thanks!

Hello, I've got 3 questions on my mind right now and I can't find answers through the searches. All of them out of curiosity as I try to learn CSS. First, why can't I get my containers height to automatically adjust to the content? Code:
#container {
position: relative;
width: 665px;
margin: 0 auto 0 auto;
background: #FFFFFF;
border: 1px solid #505050;
}
#buttons {
position: absolute;
top: 0px;
left: 0px;
height: 300px;
width: 100px;
background: #CCCCCC;
}
// HTML
<div id='container'>
<div id='buttons'>
buttons
</div>
</div>
Second question, what is with the :after I see in CSS examples. I can't get a search on it, so I can't figure out what it is for. I usually see it in a context like (.container:after). Third question, what is with the trailing slash I see before a tag is closed. I think it has something to do with HTML Strict or something. I usually see it in a context like (<tag></tag \>) thanks for the help webg I have a wrapper div 700px wide that is currently set to the following: Code: div.wrapper {
width: 700px;
height: auto;
background-image: url(../local/images/content.gif);
background-repeat: repeat;
background-attachment: scroll;
background-position: top left;
text-align: left;
padding: 0.05in;
position: absolute;
left: 50%;
margin-left: -350px;
border: 2px #000000 ridge;
}
It renders fine in IE, FF, and Opera. Since the height of the content varies, I am trying to accomplish a minimal fixed height of 700px OR larger if the content is longer than 700 px. Any ideas? I am trying to layout some content into rows using DIVs. It works fine until I get to the row of 'cells'. If I don't set the height of the container div ("transaction"), it doesn't show the white background. If I make the background of the inner DIVs white, it looks blocky (not solid white bg). I tried float options but that didn't seem to help. Any thoughts? Code:

Please notify me of the moronic mistakes I am making... thanks. Hello, I've about given up.. I've always used mostly tables, with div 's here and there. I've been trying to build some completely CSS3 / HTML5 pages.. might as well be ready for the next step.. anyways.. Both w3.org validators (css3 and html5) validate the pages, but they are not right. I thought the body could be used as the parent container.. and if not i've tried this with a 'wrapper' div also .. with an image of bottom, problem area. . So, why wont the parent container, set to 'auto' or '100%' 'grow' beyond 1760 pixels? I can set it to 2000px or what ever, but then I have to change it anytime page content changes. FYI. I use mozilla nightly, Aurora browsers on all my openSuSE systems running KDE.. Don't know if it will look diff on another system.. don't really care, but .. Thank you in advance, Landis. Hi to all, and thanks a million in advance for help. I have developed a simple online cms and everything is setup correctly but i am stuck at one place. I am unable to make width to 100% when b div is empty i mean a div = 50% width, b div = 50% width, how set it up that when a div is empty then b div goes to 100%width and when b div is empty then a div is 100% width. i hope got my question. because currently i have set in this way. wrapper div = 980px width, a div = 50% width, b div = 50% width, wrapper div end so when a div is empty then b div is still present and that area is empty it destroy the whole look. thanks arsslan The situation is very simple: Code: <div id="maindiv" style="border:1px solid #000000; width:400px; margin:0px; padding:0px;">

</div>
AS you can see, I have a main div. Inside it, I have 2 divs: red and green. If I enter text into the green div, the main div resizes automatically. But if I enter text into the red div, the main div doesn't resize, and so the red div overflows. What I need is either enter text in the red or green divs and make the main div to auto resize. (I'm using Mozilla FireFox) Any Idea? |
