CSS - Can You Position Something In Css Using Percentages?
I'm trying to piece together a sliced image using CSS, but I need it in percentages so it stays together when the window is resized! Does anybody know if this is possible or a better way to go about it?
Thanks! Similar TutorialsCan someone please explain this to me, because I'm apparently missing something. I have a div that I am using as an overlay to my site. I want this div to be 50% wide, and 50% high, and be properly centered on the screen. I was able to get horizontal centering working almost perfectly, but when it comes to vertical centering- things just don't make sense. To center, I'm setting top & left to 50% and then using margin-top and margin-left with negative values to compensate. What I assume should work (and seems to work with horizontal centering) is that if I set the margin-left to -25%, the leftmost side of my div should end up half-way between the beginning of the browser window and the center of the browser window. But if I set margin-top to -25%, by the same logic, it should move the topmost side of the div up to between the top of the browser view area and the center. But that doesn't seem to happen- at least in FF3: Code:
<html>
<head>
<style>
div#dialog
{
display: block;
position: absolute;
top: 50%;
left: 50%;
width: 50%;
height: 50%;
margin-top: -50%;
margin-left: -25%;
background-color: #FFFFFF;
border-top: #FF0000 3px solid;
border-left: #FF0000 3px solid;
border-right: #FF0000 3px solid;
border-bottom: #FF0000 3px solid;
z-index: 202;
}
</style>
</head>
<body>
<div id="dialog"></div>
</body>
</html>
Instead what happens is the top of my div ends up at the very top of the viewing area of the browser- and actually a little bit ABOVE it (outside of the view area). WHY!? If I set the margin-top to -50%, which I would expect to place the topmost edge of the div at the very top of the browser viewing area, the div disappears entirely! Yet if I set margin-left to -50%, it appears along the left side of the browser window where I'd expect it to be. Why might this be happening? Again, obviously I'm missing something. Can someone please explain? Is there another/better way of doing this? Thanks, - skubik Hi all, I've got a problem with CSS, and while I usually can fix them myself, I can't seem to find a solution to this one. I want to create a centered block with a dynamic width using almost nothing but CSS (except for the div in the HTML code). Not specified by percentages, but instead specified by the distance from both the left and the right border of the block to the body. So what I want is to specify the left and right properties of the DIV, so my first attempt was: Code: #block {
position: absolute;
top: 40px;
right: 40px;
left: 40px;
height: 40px;
}
In Opera and FireFox it worked fine, but in Internet Explorer the block had no width. Does anyone know of a way to accomplish this? I have having issues with IE displaying my page wrong. The page is http://]http://tampabay-online.org/cetr/about.php (or any page within that site) and the css can be found at http://tampabay-online.org/cetr/cetr.css It displays fine in Firefox and Opera but IE makes the content class lower from the top than the #right navigation bar (they should both be 20 pixels form the top) Any help much appreciated. Code: .content {
position:relative;
width:320px;
margin-left: 125px;
margin-top: 20px;
border:1px solid black;
background-color:white;
padding:10px;
z-index:3;
}
#right {
position:absolute;
width:200px;
top:20px;
left:500px;
border:1px solid black;
background-color:white;
padding:10px;
z-index:1;
}

Regards. Is it possible to position something below a division that has the property { position: absolute } and can expand to a varied length depending on what is contained with it? Hi, I have 2 divs. The first one is set to a specific width and height. The second one varies in size. The problem is that I need the second div to sit on top the first, and the page to position itself according to the first div. Here's an example:http://www.caillouette.com/testSite/index2.php The blank image will be white, but it's dark grey for demonstration purposes. here's the CSS: Code: .big_image{
z-index:9;
position:absolute;
left:0px;
top:0px;
margin: 5px 0x 0px 27px;
}
.big_image_blank{
z-index:0;
position:relative;
width:262px;
height:262px;
background-image: url(images/Uploads/Listings/blank.jpg);
margin: 5px 0x 0px 27px;
}
If you look at that page in IE6 you'll see the image with the woman is misaligned. It looks fine in FF and IE7. I'm not sure what I need to do to get it to align in IE6. This isn't my site design and frankly the CSS is a mess (too many css includes, etc), so I'm actually pretty lost as to how to fix this. Does it have something to do with the #leftcontent being absolute positioned? Hi, The following example is positioned as I want. Code: <div><label id="day">Day:</label><span> <input type="checkbox" name="day" value="1" />Sat <input type="checkbox" name="day" value="2" />Sun </span> </div> How do I make in next example <table> vertically aligned with <label> element? Right now <table> element is positioned next to it but way below <label> element. Code: <div><label id="lang_lbl">What languages do you speak?:</label> <span> <table><tr><td><input type="checkbox" name="lang" value="1" />English </td> <td><input type="checkbox" name="langs" value="2" />Spanish</td> </tr> </table> </span> </div> Thank you. I'm having an issue using position: relative in IE6. Basically I'm doing this: Code:
<style>
.class1 {
width: 900px;
padding: 0px;
margin: 0 auto 0 auto;
}
.floatimg {
position: relative;
top: -200px;
left: 0px;
padding: 0px;
margin: 0px;
}
</style>
<div class="class1">
<img class="floatimg" src="foo.gif" />
<p>Some text.</p>
</div>
So, basically I'm trying to move the image up a bit in the div. This works in the latest firefox and IE7, but in IE6 the image moves up, but the text does not. It stays as if the image had not been moved and this leaves a big gap. Im working on a project that required some css that I'm not used to using to pull off an effect. here is the url http://www.staging.crea8te.com/ftea I'm having one issue: Issue: the basic structure is <div1>position: relative <subdiv></div>position:absolute <subdiv></div>position:absolute </div> <div2> </div> <div3 </div> I'm not a pro at using positioning by any means with something like this and I don't understand why div2 is sitting at the top instead of at the bottom of div1. div 2 and 3 display correctly .. just arent showing up at the bottom of div1 i can paste the html and css if necessary it is just kind of a lot and didnt want to have a huge post.... any ideas? My site is RegionalCreations.com if you want to see the issue for yourself. I actually haven't encountered this issue before with the countless sites I've made. I used the basic layout of an already made wordpress theme and redesigned it for my site, I didn't change the menu position however, so I think the issue is with the original theme. Here is an image showing the problem: Well apparently I can't post an image so go to my site and then add /images/IE-CSS-bug.jpg on to see it, thanks. As you can see my image across the top is off center in IE even though it looks fine in Firefox. My menu is also spaced down in IE when it shouldn't be. Here are the locations of my stylesheets, the second 1 loads after the main 1 if you view the page in IE. (I can't post the url so go to my site and add the rest of the url on.) Stylesheet: /main/wp-content/themes/cleanmachine/style.css IE additional style: /main/wp-content/themes/cleanmachine/ie-win.css If anyone can look at my stylesheets and tell me the problem that would be great. Thanks. Im trying to get an image to center in a div. It works as long as one part of my CSS is commented out. The issues is the part that is breaking it, is required for another script to run that I have not added in due to its vast amount of code. Can anyone tell me a workaround.. leaving the MUST have code in place. Im willing to add anything to the code, just not remove if possible. Full Code Code:

Just to note, the rest of the code is for the most part an exact dup of the cross-browser image center in div code here, http://www.brunildo.org/test/img_center.html Hi devshed, First post here so I hope someone wouldn't mind giving me some help with a layout problem I'm having which I think is probably CSS related. The navbar div should be at the top of the maincontent div and to the right of the sidebar div with no gaps. I can get the desired results in FF but in IE there is a whitespace gap between the top of maincontent and navbar divs. Unfortunately I don't have it online yet to show you because I need to upgrade my hosting package first. If anyone can spare a few minutes and make any suggestions I would be very grateful. Many Thanks Jez HTML: Code:

/* Tips for sidebar1:
1. Since we are working in relative units, it's best not to use padding on the sidebar. It will be added to the overall width for standards compliant browsers creating an unknown actual width.
2. Since em units are used for the sidebar value, be aware that its width will vary with different default text sizes.
3. Space between the side of the div and the elements within it can be created by placing a left and right margin on those elements as seen in the ".twoColHybLtHdr #sidebar1 p" rule.

/* Tips for mainContent:
1. The space between the mainContent and sidebar1 is created with the left margin on the mainContent div. No matter how much content the sidebar1 div contains, the column space will remain. You can remove this left margin if you want the #mainContent div's text to fill the #sidebar1 space when the content in #sidebar1 ends.
2. Be aware it is possible to cause float drop (the dropping of the non-floated mainContent area below the sidebar) if an element wider than it can contain is placed within the mainContent div. WIth a hybrid layout (percentage-based overall width with em-based sidebar), it may not be possible to calculate the exact width available. If the user's text size is larger than average, you will have a wider sidebar div and thus, less room in the mainContent div. You should be aware of this limitation - especially if the client is adding content with Contribute.
3. In the Internet Explorer Conditional Comment below, the zoom property is used to give the mainContent "hasLayout." This may help avoid several IE-specific bugs.

I have a container DIV a with absolute position containing DIV's b,c,d each with absolute position. Code: <DIV class="a"> <DIV class="b"></DIV> <DIV class="c"></DIV> <DIV class="d"></DIV> </DIV> <DIV class="e"></DIV> DIV e has no asssigned position and is not displayed(floating in the background). I want to replace any of b,c or d (setting display to none) with e, displaying e in the position of either b,c or d. How do I assign the style of one DIV to another that is not its parent? I could if necessary place e inside a and do a swap, but I have quite a lot of DIV's like a, and would rather not have to repeat the code in each container DIV. Hope this makes sense! |
