CSS - Replacing <img> Tag With <div Style="background-image: ;"> For Speed Improvements?
Hi there,
I've read that for using decorative images in web design its preferred that you apply them as background images instead of using the <img> tag, as using the <img> tag stops the page from displaying until all the images have fully loaded in the browser, where as using a css background image will output the page completely, then start to load in the images (users can start reading the text whilst the images load in). I was just wondering really if anyone else has used this method and gone to the extreme measure if replacing all <img> tags with css background images to dramatically improve their page load speeds? So for example... before Code: <img src="my_thumbnail.jpg" alt="Thumbnail Graphic" title="Thumbnail Graphic" width="100" height="70" /> after Code: .thumb {
background-repeat: no-repeat;
width: 100px;
height: 70px;
}
<div class="thumb" style="backgound-image: url('my_thumbnail.jpg");"></div>
Just an idea really, not sure on how standard compliant it is but I might test it out later to see what speed improvements it brings. I'd be very interested in anyones thoughts Similar TutorialsHello everybody, I used the following line <td width="8" background="<?php print $image; ?>" height="15" style="background-repeat: no-Repeat"></td> and it worked well for IE, but in Mozilla the image wasn't displayed properly, so I used the following line for Mozilla: <td width="8"> <img src="<?php print $image; ?>" width="8" height="15" style="background-repeat: no-Repeat"> </img> but now the "style" property does not work, and there is a back ground repeat, how can I avoid the background repeat in Mozilla? Okay, I'm sort of learning as I go here. I had thought I would use a locker as the background, but then I decided to try learning how to do a liquid design (and positioning, oooo) and that kind of screwed me up because now I don't know how to do the locker sides (gap between door and frame like at top). In a fixed width, I'd put a bg graphic that spanned #container, but in a flexible width design...I'm confused. Do I have to do some stretchy hijinks (layered divs w/bg images) like I did w/the top? That would be very confusing, if so... This is the first of many questions to come, I'm sure. The horribly pedestrian design is at http://www.describe.org/projects/describe/ I'm taking over a departmental web page that has a whole bunch of Code: <body topmargin="0" bottommargin="0" leftmargin="0" rightmargin="0"> in the web pages. Does anyone know how to put this in a stylesheet so that I don't have to put this code in every <body> tag when I create a new page? I've searched all over and can't find a reasonable resolution. Thanks http://www.pocketfives.com/badges/triple-crown/ Don't we all just love IE7? The heading 'About the badge', in div about-badge should have some css assigned to it(background on the h2 etc..) but IE7 isn't rendering it. According to Firebug Lite it's assigned correctly. The page renders normal in all other modern browsers. The area of the page in question passes xhtml validation as well. Ideas? Hi, I have tried my hand at creating a box to set a fake image map over a background image, without luck. (But, I'm a total dork using css. Absolute beginner.) I have been trying the instructions he http://www.position-relative.com/tutorials/tute1_css_bg_image.php However, my background image is set into the body css spec, though I have only tag styles + the body's background image set using css. The rest of my page is tables, so I am wondering if I need to set the background image [for my whole page] using the .box1 spec shown on the tutorial at the link above? And if not, I don't know where / how to use the "#box-link {" noted in this tutorial. Or, if there is a different way to set the links on my css body spec'd background image... ? My background image css spec: Code: body {background-image:url("images/Header.jpg");
background-repeat:no-repeat;
background-position:top;
}
Greetings, and thank you for your help. I have a css which spec's a background image in the styles.css: #mainmenu { clear:both; padding-bottom:5px; margin-top:22px; margin-left:18px; margin-right:24px; background-image: url(images/mainmenubg.jpg); background-repeat: no-repeat; background-position:right top; text-align:left; } I am working in drupal. The image mainmenubg.jpg serves as the background for the site. My question is, is there any method (script or whatever) to have different images serve as the background so that as the user clicks thru the site, a different background appears. I realize that if I do this in static html, it would be fairly easy but this is one of the inflexibilities of drupal. Any help would be appreciated. Thanks! Pradhan what is the equivilant to <table border="1" cellpadding="2" cellspacing="0"> in css? i've tried PHP Code: table { border-spacing: 0px; padding: 0px; border-colapse: colapse; border-style: solid; border-width: 1px; } td { border-style: solid; border-width: 1px; padding: 2px; } That makes the width 2px wide though. I want it to only be one. And the padding seems to be messed up as well. I have designed one page. I am getting correct behavior in IE but there is some problem with Mozilla. Here is the code sample: <DIV class=ColumnHeader><SPAN class=noSort style="WIDTH: 6%; TEXT-ALIGN: center"><input type=checkbox id=chkSelAllAvail value="" name=chkSelAllAvail></SPAN> <SPAN style="WIDTH: 20%">Year</SPAN> <SPAN style="WIDTH:36%">Type of Report</SPAN> <SPAN style="WIDTH:24%">End Date</SPAN></DIV> I have attached both screen shots of IE and Mozilla. Can anyone help me ?? I found this great website that shows me how to create these great buttons with some images. http://www.dynamicdrive.com/style/csslibrary/item/css_oval_buttons/ How can I do this with a button instead of a link??? Is there a method or property which will tell me if the above div has visable scrollbars? I need to resize some elements based on whether the scroll bars are visable or not. I don't want to have them visable all the time, only if needed. Hello. I'm trying to avoid using the <div style="clear:both"> fix for keeping elements from floating outside of their containers in IE7. Here's the code that's working with that fix. I'd like to have a way to adjust the CSS so I can take that out.

I appreciate your help! Hi, Im using CSS, and have included the code in a separate .css file. The whole website uses DIVs and is displaying correctly in both I.E. and Firefox. Now, I need to generate a dynamic DIV using PHP, so I did this to test it out, Code: <div style="{ background: #00cc00; width:100%; height:100%;}">abc</div>
But the problem is that it displays correctly in I.E. but not in FIREFOX, all the attributes that I have specified within the style="{}" tag are NOT at all applied in FIREFOX. Only the text "abc" is displayed in firefox and the style, including the background colour is not applicable at all! Please tell me what Firefox is upto? Thanks! Your sisncerely, mbk, mbkweb.

I haven't used CSS/html in awhile but if anyone can help me either "fix" the content box so it appears like mockup which would be centered on my screen as my resolution is 2560X1600(30") and just repeat the <div's> when needed. Hope someone can help me with my question. http://stuweb.cms.gre.ac.uk/~as234/full/full.htm some problems: in IE the menu at the top is "block" level but i want it to be in a line? whereas in ff its ok! in ff, one of the menu image (called "main" on the left of review) doesnt appear but if u hover over it, u will see the rollover image! the background colour should be grayish however that DOESNT happen! hey, i have 2 CSS problems. number 1: my main <div> is not centered in IE. it's fine in FF, mozilla, and opera, but it stays all the way to the left in IE. Code: #main { width: 77%; margin: 0 auto; border: 1px solid #999; overflow: auto; background: #970303; color: #FFF; -moz-border-radius-topleft: 20px; -moz-border-radius-topright: 20px; -moz-border-radius-bottomleft: 20px; -moz-border-radius-bottomright: 20px; }
Code: <div id='main' align='center'> number 2: i can't figure out this gradient background stuff. i have an image, 1 px wide and 1000 px high. it works fine, but once theres enough information on a page, and its longer than the 1000px, the image starts over and looks extremely unprofessional. how can i make so that the one gradient image is stretched out for the length of the page? thanks. (I originally posted this at the end of another of my topics but I don't think it was seen). I have just noticed this problem in firefox (may happen in other browsers) but I couldnt make it happen in IE6. After the first load of the page or after a "hard refresh" (ctrl + F5) the middle and right column do not "shift up" and leave a gap. (see attached picture). But if I refresh (just F5) firefox shifts them up to display the page as it should be seen. Example Picture The site itself. Any ideas? Hi guys, For a pure CSS site, is it still necessary to have height="82" and width="82" in <img ... /> ? Moreover, is it depreciated to have a size="25" tag in <input elements? (I know it could ba handled in CSS but nice to have directly in the html). Thank you Hi, I'm trying to build a nav using css, I need to style each <li> within the nav becuase they need to be different lengths on the page. I have had it working fine on IE but I can'#t get it working for for any other browser. Does soneone know how I can style each of my list items accordingly, notice the different block lengths for each one which is very important. I have tried both id="Style" and class="Style" and no joy, I have also tried #nav ul li li li li li a:hover in my style without id or class in my HTML Here is my Html PHP Code: <DIV id="nav"> <ul> <li id="1"><a href="Home">Home</a></li> <li id="2"><a href="About-us">About us</a></li> <li id="3"><a href="FlexNews">FlexNews</A></li> <li id="4"><a href="Careers">Careers</A></li> <li id="5"><a href="Contact">Contact</A></li> </ul> </div> Pretty straight forward, now my css PHP Code: #nav { width:1005px; vertical-align: middle; text-align: left; } #nav ul { list-style: none; padding: 0; margin: 0; } #nav li { float: left; text-align: left; } #1 a{ line-height: 20px; float: left; width: 215px; display: block; color: #000000; text-decoration: none; text-align: left; font-family: Arial, Helvetica, sans-serif; font-size: 11px; text-indent: 17px; border-right-width: 2px; border-right-style: solid; border-right-color: #FFFFFF; } #1 a:hover { line-height: 20px; float: left; width: 215px; display: block; color: #FFFFFF; text-decoration: none; text-align: left; font-family: Arial, Helvetica, sans-serif; font-size: 11px; background-color: #33A02C; text-indent: 17px; border-right-width: 2px; border-right-style: solid; border-right-color: #FFFFFF; } #2 a{ line-height: 20px; float: left; width: 211px; display: block; color: #000000; text-decoration: none; text-align: left; font-family: Arial, Helvetica, sans-serif; font-size: 11px; text-indent: 17px; border-right-width: 2px; border-right-style: solid; border-right-color: #FFFFFF; } #2 a:hover { line-height: 20px; float: left; width: 211px; display: block; color: #FFFFFF; text-decoration: none; text-align: left; font-family: Arial, Helvetica, sans-serif; font-size: 11px; background-color: #33A02C; text-indent: 17px; border-right-width: 2px; border-right-style: solid; border-right-color: #FFFFFF; } #3 a { line-height: 20px; float: left; width: 211px; display: block; color: #000000; text-decoration: none; text-align: left; font-family: Arial, Helvetica, sans-serif; font-size: 11px; text-indent: 17px; border-right-width: 2px; border-right-style: solid; border-right-color: #FFFFFF; } #3 a:hover { line-height: 20px; float: left; width: 211px; display: block; color: #FFFFFF; text-decoration: none; text-align: left; font-family: Arial, Helvetica, sans-serif; font-size: 11px; background-color: #33A02C; text-indent: 17px; border-right-width: 2px; border-right-style: solid; border-right-color: #FFFFFF; } #4 a { line-height: 20px; float: left; width: 184px; display: block; color: #000000; text-decoration: none; text-align: left; font-family: Arial, Helvetica, sans-serif; font-size: 11px; text-indent: 17px; border-right-width: 2px; border-right-style: solid; border-right-color: #FFFFFF; } #4 a:hover { line-height: 20px; float: left; width: 184px; display: block; color: #FFFFFF; text-decoration: none; text-align: left; font-family: Arial, Helvetica, sans-serif; font-size: 11px; background-color: #33A02C; text-indent: 17px; border-right-width: 2px; border-right-style: solid; border-right-color: #FFFFFF; } #5 a { line-height: 20px; float: left; width: 183px; display: block; color: #000000; text-decoration: none; text-align: left; font-family: Arial, Helvetica, sans-serif; font-size: 11px; text-indent: 17px; } #5 a:hover { line-height: 20px; float: left; width: 183px; display: block; color: #FFFFFF; text-decoration: none; text-align: left; font-family: Arial, Helvetica, sans-serif; font-size: 11px; background-color: #33A02C; text-indent: 17px; } Here is an exmple link http://dev.121design.co.uk/flextrade2/ Works fine in IE but not in Firefox, heres hopling someone can help. Thanks in Advance, tried so many different methods and none seem to work. Cheers, Stuart Hi, not sure if it is possible but i thought it may be possible in CSS... I was wondering: * I have a shopping cart (using JS) * A CSS based Navigation which is "View Shopping Cart" * An form button called "Add to cart" ** I want the CSS based Nav, to be hidden, until the user clicks on the form button, then it is visible, so that the user can click on it... Anyone know how this is done??? Cheers Jackson I purchased a WordPress theme from Orgnanic Themes(who are no longer providing assistance) a few weeks ago and wanted to make a few minor changes(literally, all I did was replace images(header, slider prev/next buttons, background, footer, and the logo). In doing so, I went astray somewhere and messed up. I'm more of a designer than a developer so I'm at a complete loss now. How do I fix it?? Any help or advice would be greatly appreciated.
