Similar TutorialsI have an image link which I want to display at 50% opacity and when the user hovers over it I want it to be 100%. My code doesnt seem to be working tho? Please could someone help me... <html> <head> <title>Untitled Document</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <style type="text/css"> <!-- .fadein { } a.fadein { filter: alpha(opacity=50); } a.fadein:link { filter: alpha(opacity=50); } a.fadein:hover { filter: alpha(opacity=100); } --> </style> <head> </head> <body> <a href="gfdg.html" class="fadein"><img src="First.gif" width="257" height="130" border="0"></a> </body> </html> I'm working on a site that's a single php page with CSS file. The site uses the same rotating image script, in 2 locations. In the one location, it rotates the background image of a div. I've set the opacity to 0.7, alpha filter at 70. This is working properly - it is affecting the opacity of the background image as I want. The problem is that it is also affecting the opacity of static images that are contained within that same div. Any ideas on how I can keep the opacity of the rotating background image, without affecting the opacity of the static images that are on top of the background?

Regards, ChesterNerd I have a problem involving the ie only filter alpha(). My problem is that any <div> that is nested inside another becomes clipped, see example: Code: <html xmlns="http://www.w3.org/1999/xhtml" lang="en">
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<style type="text/css" media="screen">
#inBusinessHolder {
position: relative;
}
div.inBusinessBox {
display: block;
filter: alpha(opacity=80);
position: absolute;
width: 250px;
height: 80px;
border: 1px solid black;
background: #cff;
}
</style>
</head>
<body>
<div id="inBusinessHolder">
<div class="inBusinessBox" style="top:70px;left:100px;">text</div>
<div class="inBusinessBox" style="top:140px;left:110px;">text</div>
<div class="inBusinessBox" style="top:210px;left:120px;">
text
<div class="inBusinessBox" style="top:10px;left:-10px;background:#cf6 z-index:1000">text</div>
</div>
</div>
</body>
</html>
Anyone got any ideas? It's like the parent container is behaving like a clipping rectangle! Is there Opera compatible code for filter:alpha or -moz-opacity? Well, I have a couple png images that are using a transparent background. As most of you probably know, it looks great in every browser except IE for the PC. It looks like complete *** in that browser. Now I looked all over the net for a fix for this and found this in Microsoft's library of fixes for their products and found the AlphaImageLoader. Tried using their own code and the same code I found on a dozen other sites and it still isn't loading the transparency, so I'm just curious what I am doing wrong. Here is the code: Image HTML Code: <div id = "welcome_image"> <img src = "/testing/inertia/images/home/welcome.png" alt = "Welcome" /> </div> Image CSS Code:
#welcome_image
{
position: absolute;
top: 10px;
left: 10px;
width: 168px;
height: 216px;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src="/testing/inertia/images/home/welcome.png", sizingMethod="scale");
}
is there any way to have the background of a table be at 50% opacity and the text be at 100% opacity? i've been playing with this code: style="filter:Alpha(Opacity=xx)" ...where xx is 50 or 100 and have placed it within the <table> tag and also within a <font> tag, but nothing seems to work. the font wants to be the same opacity as the table. is there any way around this? on a possible workaround, i've tried using semi-transparent PNG file as the background of the table, and that didn't work. i couldn't get the PNG file to do semi-transparent. it wanted to do a diffusion transparency, which looked like @ss. Hello, im new to this forum ( A pleasure to meet everyone! ) I was browsing through the forum and could not find exactly what my problem is. I am trying to make a filter for my CSS code with the dropshadow effect on text. Eg: .content { color: White; text-align:justify; line-height:12px; font-family:tahoma,arial narrow,arial; font-size:9px; Filter: Alpha(Opacity=70) DropShadow(Color=#8F5A3A, OffX=1, OffY=1, Positive=1); } The problem is its just not working Its hard for me to get the colors correct to begin with because of the BG the text is on. But If I could get the Alpha(Opacity) to work with the DropShadow the text will be significantly more visible and would work fine. Any suggestions? or Solutions? Keep in mind im NOT very knowledgable in a lot of new things yet Help much appreciated- Thanks a lot! Hiya, been playing around with trans PNGs and appreciate Firefox more and more with each passing hour!! What's the best way to get PNGs with alpha channel transparency to work in IE6, so far I've tried the .htc script mehod which works OK, except, on my PC it asks if I want to execute the script each time I open or refresh the page. Don't know if it would do this on my web server and haven't tried it yet. Is there another equally straight forward way to deal with this? I thought about browser sniffing and then giving IE6 a nasty transparent GIF and everything else a PNG. What does everyone else think? John. If I set a height for my LIs, then IE does not increment the list item. It shows a. a. a. a. instead of a. b. c. d. Actually it's the same for any list-style-type. It never increments the list-type, even when it's just the default style. I couldn't find any other mention of this anywhere. Does anybody know what causes this bug, or if there's a way to fix it? Here is some code to reproduce: Code:
/* CSS */
#qform ol {
list-style-type:lower-alpha;
}
#qform ol li {
color:#333;
height:25px;
margin:10px 0;
padding:0 0 0 20px;
}
#qform ol li input {
margin:3px 5px 0 0;
}
#qform ol li label {
margin:0;
}
<!-- HTML -->
<form id="qform" action="index.php" method="post">
<fieldset>
<ol>
<li>
<input type="radio" id="rada" name="answer" value="a" /><label for="rada">Once</label>
</li>
<li>
<input type="radio" id="radb" name="answer" value="b" /><label for="radb">Twice</label>
</li>
<li>
<input type="radio" id="radc" name="answer" value="c" /><label for="radc">Three Times</label>
</li>
<li>
<input type="radio" id="radd" name="answer" value="d" /><label for="radd">A Lady</label>
</li>
</ol>
<input type="submit" value="OK" />
</fieldset>
</form>
In IE6, that will display a list with a, a, a, a. Remove the height from #qform ol li and it works as it should. Thanks, I'm sure this can be fixed... But I'm not sure how! I was doing the final adjustments and cross-browser tweaking when I stumbled upon this issue... I'm using a CSS with the following background tag: Quote: background: #E8E9EA url(img/test.png) repeat-x 0 8px; My PNG is 32bits, and of course, this works OK in Firefox, etc.. But not in MSIE! ( tested under 6.0.2900.x ) - Instead of correctly blending the PNG with the table background, it displays full white rects as backgrounds. I tried a few ms-ie "holy" fix scripts, etc. None of them worked on this special case. Any ideas?. I wouldn't like to work-around this one... Thanks. Is it possible to overlay a colour onto a grayscale image to make it that colour with css? Such as using the alpha channel? Image in question would be a transparent background gif file. A lot has been added to the MS IE css site since I last visited it. In particular it seems I should be able to load a PNG image without the horrible rendering of IE and then filter it with this to keep it's original transperency. Not requiring to settle for gif or keep copies of all images in gif format. Code: filter:progid:DXImageTransform.Microsoft.AlphaImageLoader() I can't seem to get it to work though. Here is my atempt. Code:
/*include line*/
<!--[if ie 6]>
<link rel="stylesheet" type="text/css" href="style/iemain.css" />
<![endif]-->
/*css*/
#nav_main{
margin-top:1em;
margin:0;
float:left;
clear:left;
width:122px;
background-image:url('../image/not_a_real_image.png');
filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src='../image/nav_bg.png', sizingMethod='scale');
}
It reveals nothing, because this is not an image doens't exist. When the :not pseudoclass is used with an element selector in Firefox, it works as expected, excluding the selector inside the parentheses. But used by itself or attached to the * selector, it applies the rule to ALL elements. This unexpected behavior can be exploited to write Mozilla-specific patches to your CSS code. example:
html4strict Code: Original - html4strict Code <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html> <head> <title>Testing :not Hack</title> <style type="text/css"> :not([id]) p { font-weight: bold; } </style> </head> <body id="thisthing"> <p>This is a test.</p> <p id="test">This is a test.</p> <div>This is a test.</div> </body> </html> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> The idea is to set the ID of the parent and browsers which correctly interpret this selector will not apply the rule to anything; also those browsers which don't already support it will simply ignore it. The :not selector is part of the new CSS3 recommendation. Here's just the css code for the hack: css Code: Original - css Code :not([id]) example { /* Moz/FF/Netscape code here */ }
:not([id]) example {
Not working in mozilla This does not render well in Mozilla Firefox, but is okay in IE. Please Help Us........ Hello Everybody: I use this: Code: filter: progid:DXImageTransform.Microsoft.BasicImage(Rotation=1); to rotate a table 90 degrees right. It works pefectly. When the table is in horizontal position, the text looks good, but when the style is aplyied, text looks like printed with a 9 dot impact printer, can I avoid this?, Is there any other way of doing this without using that style?. Thanks in advance hello, i have a problem with aplha opacity filter in IE6. My div looks like this <div style='width:0%;height:0%;background-color:white;filter:alpha(opacity=50);-moz-opacity:0.5;opacity:0.5;color: blue;' >" + label + "</div>"; This works well and good i have one more div prior to this and I want to display both of them in line. For that when I apply position:relative;display:inline; The opacity filter is not showing any effect. any help would be appreciated... Thanks, Robust Hi I know we can not show th tags with css as such th{display:none} but is there any way to filter out which <th tags not to show? rather than not displaying any? maybe only the ones with id='not show' is this possible? Thanks discovered whilst working on asp where i use '' for comments and tried to comment out a line in the css file the same way... this should technically work by breaking the whitespace and create an invalid rule but IE yet again responded differently... Code: ""item:attribute; ''item:attribute; //item:attribute; ignored by opera 7.54 netscap 7.02 firefox 1.0.4 read by IE 5.01 IE 5.5 IE 6.0 "item:attribute;" 'item:attribute;' ignored by all read by IE 5.01 interested to see how the mac browsers respond but it looks like a better IE5.0 inline filter than Code: _item /**/: /**/attribute; ! Hi, I am trying to validate my CSS using the Jigsaw CSS Validator. http://jigsaw.w3.org/css-validator/validator I keep receiving the following error. Quote: Line: 1895 Context : #save attempt to find a semi-colon before the property name. add it Line: 1895 Context : #save Property progid doesn't exist : DXImageTransform Line: 1895 Context : #save Parse Error - DXImageTransform.Microsoft.AlphaImageLoader(src='../../../../includes/images/iconSave.png', sizingMethod='none'); Line: 1896 Context : #save Parse error - Unrecognized : } With regards to the following piece of text: Code: #save

}
#save[id]
{
height:40px;
width:40px;
background-image:url(../../../../includes/images/iconSave.png);
}
Is it because i'm trying to use an MS Filter in my CSS, if so where else can I place this - in the code? Doesn't that defeat the object of CSS though? Any help much appreciated. Thanks, Jay. Hi. I have this DIV element which has content inside, and which has some JS code implemented on it. Every thing works like a charm. Then, I add a transparent PNG background. Everything's still working. But for the PNG background to be transparent in IE I have to set a filter on the DIV, like this: CSS Code: Original - CSS Code * html #master_container /* This is the DIV element */ { background-image: none; background-color: transparent; filter:progid:DXImageTransform.Microsoft.AlphaImageLoader (src='./images/main_window_glass.png', sizingMethod='scale'); } * html #master_container /* This is the DIV element */ Which in turn, for some blunt and very unknown reason, cancels any functionalities of the content inside the DIV or the JS code relative to the DIV. Here, take a look: http://pilau.phpnet.us/mctours/index.html Compare in FireFox and IE6 and tell me if you have ANY clue! Thanks, very much, frustrated Pilau |
