CSS - Absolute Positioning By Center Of Object
hello
Is it possiable to position an image absolutly using its center as a the measurement refrence as opposed to the upper left corner. If so how would I do this. Thanks Nick Carlevaris Similar TutorialsI have the following page. I need the image and all the ajax to be centered on the page, no matter how the user resizes it. I've tried several different methods, but it always seems to screw up the positioning of the ajax buttons. I've only just started mucking round with CSS. Just by looking at other peoples sites and seeing how they do something, and then mucking around with what they've written to learn it. What I am trying to do at the moment, is just have a blank page with at the absolute center (Vertical and Horizontal) of the screen have some text. But the text is only horizontally centered not vertically. Heres the codes: In seperate stylesheet Code: #center { position: absolute width: 100%; height: 100%; text-align: center; vertical-align: middle; } and in the page Code: <div id="center"> <p><span class="aus">Austrlia</span><br> <span class="contact">admin@sixfootone.com +61 412 587890</span> </p></div> Any ideas? Thanks I have a DIV that is positioned as absolute and have used the required CSS to make it centered. But when viewed in Internet Explorer it is 1 or 2 pixels off-center?? Here is the CSS code: Code: div.mpheader { position: absolute; display: block; overflow: hidden; padding: 0px; top: 0px; width: 900px; height: 655px; margin-top: 0px; margin-left: -450px; left: 50.0%; background-image: url(images/header.png); } and the HTML code in the body: Code: <div class="mpheader"> </div> and here is the link to the site: highriserocks.com/maydayparade I have other CSS for A classes which are inside the DIV tags also but it's just the main image that is slightly off center. Any ideas?? Much appreciated! Adam Hi I'm having a bit of trouble with a DIV/CSS layout - 2 DIVs are inside a 100% height 100% width container DIV. The first (top) DIV is the content and the second (bottom) DIV being a 100% width 240px height footer DIV. I can make the footer stick to the bottom of the page and display fine no problem, however, I am having trouble getting the content div to fill only the area above the footer. If I specify a 100% height for it then it extends the entire height of the page and content disappears behind the footer. Plus, I want to absolutely center the content in the space above the footer, not the absolute center of the whole page, which is all i am acheiving with 100% height! Basically, I need the content DIV to extend 100% then subtract the 240px height of the footer - I suspect it's not wise to mix px and %, however. I have attached an image to help with my probably confusing explanation! I do have a workaround using tables, which I would ideally like to avoid, particularly as it does not support IE6/7 browsers. If a solution can be acheived which uses JavaScript to format the DIVs, then I am open to any suggestions anyone may have. Thanks R Good morning, I've been working on my site, and it's in its final stages, but I'm experiencing a problem I can't figure out. I have a floating bar with all of my navigation links in it which is absolutely defined with the following code: Code: #headerBar { /* sets position of floating bar */ position: absolute; clear: both; top: 57px; left: 0px; padding: 0px; margin: 0px; width: 100%; filter: alpha(opacity=50); -moz-opacity: .50; opacity: .50; } The problem I'm experiencing is that in Firefox, Safari, and Opera, the bar appears magically in the perfect position, however, in Internet Explorer, the bar is 5-10 pixels higher than it should be. The url is: http://www.alokw.com Any suggestions? Thanks! I think the best way to explain this is by example, if you go to this page: http://lifeyouwant.workinprogress.co.uk/how-we-work You will notice the drop down menu works fine in Firefox, Safari, Opera etc. However when it comes to IE7 the drop down menu is positioned too far to the right. Has anyone got any ideas how I can get this to display correctly in IE7 (like it does in Firefox). I would prefer to try not to use a hack for IE7. ANy ideas would be great! Thanks. Hi, I was wondering if any CSS experts could give me some advice on how to position elements on a page. Right now I'm really into using absolute positioning because it just seems so easy to place things on an exact point on the screen irrespective of all other elements, but I am wondering whether that is considered bad practice, any advice would be greatly appreciated. Thank you in advance for any correspondence. Hi everyone, I just stated handcoding and I am having a great time. Everything seemed to be going well on my first site until I previewed it on IE. After solving the nasty png issue, I realized that the two elements that I have absolute postioned a) screw the layout up in IE6 b) don't appear all together in IE7 and IE8, but doesn't screw up the flow. The elements are an arm that is supposed to hang off the left side, and hair that sits above the contentwrap (you will understand once you look) It renders perfectly in Firefox, safari and google chrome. Go figure. I read I can't put hyperlinks because of spam, so if you don't mind helping out, please visit: w w w . goscoblog. com/test/index.html Thanks In advance Now i have used some of this on one of my designs and at 1280x1024 resolution it looks perfect however if you decrease the resolution then it move the image into a place i dont want it to be. Now is there a way around this or am i just going to have to put the "this site is best viewed at 1280x1024" sign on it? Hello All. I have very little experience with coding and the likes so i don;t even think I'm allowed to post on these forums? hehe BUT, I have ran into a problem on myspace with code. I am trying to create a linkable image I believe it would be called. <a href="website url"> <img src="wouldnt let me post url's" /> </a> Thats what i have so far. I beleive that means when the image is clicked it takes y ou to the homepage. (I dont even know if that is CSS, so i apologize if this is the wrong forum I'm posting on.) I am trying to get the image to appear around 300 pixels from the left and 400 pixels from the top. I had looked on google for a solution of some code to help me out and all I found was thing saying how 'Absolute Positioning' was what was needed. I tried adding various bits of code I had found to the code i currently had, and some of them would almost work, but text would appear after the image and it would be clickable also. I was just wondering how I could place the image were I want it and when it is clicked on, it takes you to the homepage. Thanks in advance to anyone who replies, and also apologies for my incredible noobness. -Connor Hello everyone, I would like to ask for any and all help on solving this problem I am having. Well recently I used to make all of my web sites in tables until I came upon an article saying you should use CSS and absolute positioning. Therefore, my problem is this, If you go to this partially completed site, http://sykotic-designz.org/newsite/index.html. You will now notice that there are two 'shadow' images. One on the left and one on the right. The one on the left works fine. Test it by making your browser window smaller and bigger. You will notice the right shadow moves. I have tried various alternatives like using a table just for the one image but you still need to use absolute position and did not work, I have messed with displaying absolute position by % and by pixels. But it doesn't want to seem to work either. I am mainly having problems probably because I am new to the DIV tags in which I use entirely through out this page, I am not sure if CSS will help at all. You can view the source of the page if you wish. I appreciate and and all help you may provide, thanks! Hey guys, This is my first time messing with absolute positioning, and I am in a pickle. I have created a website and it contains a services page. On the list of the services, when you scroll over each word, a block of text describing that particular service pops up. Now, I have placed the box using <span>'s and hidden blocks. My problem is that when I change screen resolutions, the placement of the box changes. I am looking for a resolution-independent workaround for this, so that others running 1024, 1280, etc wont have a problem viewing the site correctly. I have searched the web dry it feels like. Maybe I'm just bad at looking, but its the last thing I need to do before putting up the site. Check out the page and source code he URL Additionally, this is the code I used to make this (it's Eric Meyers PURE CSS codes): Code: <style type="text/css"> <!-- div#links a:hover {text-decoration: none; background: #698165;} div#links a span {display: none;} div#links a:hover span {display: block; position: absolute; top: 535px; left: 233px; width: 377px; height: 230px; padding: 5px; margin: 10px; z-index: 100; color: white; font: 10px Verdana, sans-serif; text-align: justify;} div#links a:link { text-decoration: none; color: white;} div#links a:visited { text-decoration: none; color: white;} --> </style> then the code is activated by: Code: <a href="#">Mowing <span>Service Landscapes will tend and maintain your lawn with the most substantial of detail and care. Our services will provide you with a beautiful, healthy landscape that will turn heads. If you are looking for quality and dependable service that you can turn to time and time again, look no further than Service Landscapes. </span> </a> Any help would be greatly appreciated, and thanks in advance! Hey, I have a bit of a problem and am very new to using CSS. On a web site I am making I have used a CSS style sheet to position a table on the page. This what the coding on the sheet is like: table { position: absolute; top: 117px; left: 120px; width: 167px; } However, I have a second table that I wish to position using absolute positioning, but I have no idea how the browser can tell the difference between the two. As you can see above, the first table has been identified as 'table', but what can I call the second table so that I can use different pixel settings without effecting the first? IE absolutely sucks (pun intended). Or mayhaps its the developer. In any case: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>My site</title> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" /> <style type="text/css"> #top_main_content { width: 955px; } #top_main_content ul { float: left; list-style-type: none; border-spacing: 0; margin: 0; padding: 0; text-align: right; border-top: 1px solid #f1f1f1; height: 243px; width: 266px; } /* end #top_main_content ul */ #top_main_content ul li { vertical-align: middle; margin: 0; padding: 0; border: 0; color: #686868; width: 266px; border-bottom: 1px solid #f1f1f1; } /* end #top_main_content ul li */ #top_main_content ul li a { line-height: 26px; display: block; margin-right: 5em; color: #686868; width: 266px; } /* end #top_main_content ul li a */ .indent { padding-right: 1.5em; } #top_main_content ul li a:hover { background: #cfcf00; color: #000000; } /* end #top_main_content ul li a:hover */ #top_main_content #rotating { float: right; width: 687px; height: 242px; border-bottom: 1px solid #f1f1f1; border-top: 1px solid #f1f1f1; text-align: right; } /* end #top_main_content img */ #default_div { position: absolute; visibility: visible; } /* end #default_div */ #div_a { position: absolute; visibility: hidden; } /* end #div_a */ #div_b { position: absolute; visibility: hidden; } /* end #div_b */ #div_c { position: absolute; visibility: hidden; } /* end #div_c */ #div_d { position: absolute; visibility: hidden; } /* end #div_d */ #div_e { position: absolute; visibility: hidden; } /* end #div_e */ #div_f { position: absolute; visibility: hidden; } /* end #div_f */ #div_g { position: absolute; visibility: hidden; } /* end #div_g */ #div_h { position: absolute; visibility: hidden; } /* end #div_h */ #div_i { position: absolute; visibility: hidden; } /* end #div_i */ </style> </head> <body> <div id="logo_search"> <div id="logo_container"> </div> </div> <div id="base"> <div id="main_block"> <div id="main_content"> <div id="top_main_content"> <ul> <li><a href="#">Link 1</a></li> <li><a href="#">Link 2</a></li> <li><a href="#">Link 3</a></li> <li><a href="#">Link 4</a></li> <li><a href="#">Link 5</a></li> <li><a href="#">Link 6</a></li> <li><a href="#">Link 7</a></li> <li><a href="#">Link 8</a></li> <li><a href="#">Link 9</a></li> </ul> <div id="rotating"> <div id="default_div"><img src="images/test_image_main.gif" alt="" /></div> <div id="div_a"><img src="images/test_image_a.gif" alt="" /></div> <div id="div_b"><img src="images/test_image_b.gif" alt="" /></div> <div id="div_c"><img src="images/test_image_c.gif" alt="" /></div> <div id="div_d"><img src="images/test_image_d.gif" alt="" /></div> <div id="div_e"><img src="images/test_image_e.gif" alt="" /></div> <div id="div_f"><img src="images/test_image_f.gif" alt="" /></div> <div id="div_g"><img src="images/test_image_g.gif" alt="" /></div> <div id="div_h"><img src="images/test_image_h.gif" alt="" /></div> <div id="div_i"><img src="images/test_image_i.gif" alt="" /></div> </div> </div> </div> </div> </div> </body> </html> In any case what will happen with this code is when a user rolls over a link (not shown in code), the visibility of the corresponding div will change. All of this renders and works correctly in FireFox, Opera, and Safari. In IE 7 and 6, it works correctly, but does not render correctly. In IE 7, the images (all 687 x 243) seem to be indented 687 pixels. In IE 6, there is a lot of trailing border in the links and that is pushing the images below the menu and will then probably have the same problem IE 7 is having. Thoughts? Edited to add that I solved the IE 7 problem by removing text-align: right; from the #top_main_content #rotating div. I still have the IE6 problem however. Hey people. I'm kind of new to CSS (well not new, just unfamiliar), and I need to ask the old question about absolute positioning, which I haven't managed to find a satisfactory answer to on the net. I downloaded a script for a drop down menu. The page on which it appears is made up of a table, and the headers of menu is in a row across the top. The menu items are in their own tables: <div id="dropdown1" style="left: 257; visibility: hidden; width: 81; position: absolute; top: 299; height: 53"> <table class="popup" onmouseover="clearTimeout(timerID)" onmouseout="timerID=setTimeout('closeall()',200)" cellspacing="0" cellpadding="2" width="79" height="15" border="1"> <tbody><tr><td>Item 1<br>Item 2</td></tr> </tbody></table> </div> And as you can see, they use absolute positioning. Unfortunately, this means that when I change the text size on my browser, the menu headers and the menu items are not aligned. I tried using table id=dropdown1, but this resulted in a huge gap between the menu headers and the rest of the page, where the hidden menu items were. I realise changing text size will always be a problem when using absolute positioning in CSS, so I was wondering if anyone had any suggestions on an alternate method? Or if not, atleast what text size most people use, so I can set it to align for the majority of viewers? Or if it's possible to do a similar menu in a different (understandable) language? I appreciate any help, MKK (Before you ask, no, the page is not online. I know this makes it harder to find a solution, but my webhosting company just disappeared - "failed to pay server bills", so I currently have no web space) Hello Can anybody explain me the difference between the absolute and the relative positioning methods? If i use nested <span> elements in a table row which one is suitable? And also what the "Z-index" property tells us? I am so confused with these terms nowadays.And waiting your help. Thank You Very Much... I have my website at omel.co.cc I have a menu that I positioned absolute, but when I view in a different resolution the menu changes position, I have put a parent div positioned relative but every time I scroll the menu moves which I do not want to, when positioned fix, the position of the menu goes off, on different resolutions and when I resize the window, I have googled these, hope someone could help, or I just did not googled enough? K...I have an absolutely positioned toolbar in a search tool page. There are instances where the toolbar (on the left) is longer than the actual (non-absolute) results. When this happens, IE refuses to scroll for the absolutely positioned content! Anyone know what I can do about this? It's a little...crappy. MPEDrummer Hi, I'm not sure if this is possible or not, but I can't get it to work accurately, and I wondered if anyone could give me some help. I would like to position a layer at an absolute position (T:128 L:253) which is no problem, but then I would like that layer to have a relative width from that fixed point, expanding/contracting to whatever size the browser is. I've tried several different things, but can't seem to get this particular setup. If I set the width of the layer to 100%, the layer positions itself correctly on the page, but pushes beyond the right hand side of the browser causing a horizontal scroll. Has anyone done this before? Am I missing something critical? or is this impossible to do with layers/css Thank you! |
