I used the custom cursor property for the task, but it does not work with ie browsers. I used the following snippet.
<html>
<head>
<title>Custom Cursor</title>
<style>
h1{
cursor: url(http://www.franco.it/Images/Lookf.png), auto;
}
</style>
</head>
<body>
<h1>Custom Cursor</h1>
</body>
</html>
It works in Chrome, Firefox, and Safari - everything except IE. Some articles say I should use the .cur format but how do I convert an image to cur? I couldn't find a proper link to convert it.
Thanks.
IE doesn't support png format for cursor.
You need convert to "cur" format.
The css code will look like this
h1{cursor: url(http://myworkstudio.com/app/cursor1.cur), pointer}

I have been trying to solve this for 2 hours now but no luck. The less code snippet works fine in all browsers except IE8. I checked IE8 supports :after and :before
I'm using standard IE8 doctype, using HTML5 shiv and also not running this in compatibility mode?
#media print {
.app-header .large-header {
.logo span,
h1,
.action-links {
display: none;
}
.logo:before {
content: url('images/logo.png');
position:absolute;
top:0;
left:0;
width:150px;
height:28px;
}
}
}
UPDATE
Issue is that IE8 doesn't support printing content url. The workaround is to use an image instead.
IE8 does not support media queries this: #media print {} is not supported.
create a separate css for IE8 and in the HTML put a conditional like this:
<!--[if lt IE 9]>
<link rel="stylesheet" type="text/css" media="all" href="style-ie.css"/>
<![endif]-->
See for yourself https://msdn.microsoft.com/en-us/library/ms530813(v=VS.85).aspx
Dynamic HTML (DHTML) expressions can be used in place of the preceding
value(s). As of Windows Internet Explorer 8, expressions are not
supported in IE8 Standards mode. For more information, see About
Dynamic Properties.
I don't know about your markup but is it an option to remove the background image of the logo and use an actual <img> tag for it?
That way you would not need to change a lot of styles for printing pages. You should also keep in mind that there are a lot of printers out there, which disable background-imagery and background-colors by default!
According to OWASP recommendations, CSS values from an untrusted source should be escaped.
Link to OWASP cheat sheet: https://www.owasp.org/index.php/XSS_(Cross_Site_Scripting)_Prevention_Cheat_Sheet#RULE_.234_-_CSS_Escape_And_Strictly_Validate_Before_Inserting_Untrusted_Data_into_HTML_Style_Property_Values
In an attempt to follow these recommendations I am escaping my CSS values using Microsoft's AntiXss library, specifically System.Web.Security.AntiXss.AntiXssEncoder.CssEncode(value).
This produces a stylesheet that looks like this:
a,
a:visited {
color:\00002329c;
}
a:hover,
a:active {
color:\000023036;
}
body {
background:\000023eee;
color:\000023333;
font-family:Arial;
font-size:15px;
}
This works fine for IE and Chrome, but Firefox will not recognize the escaped values.
Is this a bug with Firefox or am I misinterpreting how to implement the OWASP recommendation? Also, if this is a Firefox shortcoming then what is the best work around?
I did a quick POC, and at the outset it does look a bug in firefox. For simplicity here's the code I used and tried to open this webpage in IE, Chrome, Safari, and Firefox. With IE, Chrome, and Safari, the background gets changed to #FFCCCC, however in Firefox there is an error in the console.
"Stylesheet could not be loaded." Expected color but found '\#FFCCCC'. Error in parsing value for 'background'. Declaration dropped.
Sample Code:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
<style>
body {
background:\000023FFCCCC;
font-family:Arial;
font-size:15px;
}
</style>
</head>
<body>
<p>Test</p>
</body>
</html>
Out of curiosity, I have gone ahead and raised a bug with Mozilla here - https://bugzilla.mozilla.org/show_bug.cgi?id=1172570
I also doubted that it could be an issue with respect to the #charset, but couldn't get it to working either. Till the guys at mozilla gets back, if you find a workaround please post back.
This comment is not a "fix", but it sheds some light on the issue.
Unless I am mistaken, this issue only seems to effect sites loaded through standard http but not those loaded securely through https. In other words, Firefox will recognize the escaped values... but only when the site is loaded through https and not http.
http://domain may not load properly but https://domain will.
I have a weird issue where IE8 doesn't appear to render my background image using imported CSS.
Because of IE8's problematic issues and its lack to support many CSS3 elements, I am forced to use conditional logic to load specific stylesheets for my site content. I am using MVC4 and my _Layout page has the following in the header:
<link href="#Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<!--[if lt IE 9]>
<link href="#Url.Content("~/Content/DeprecatedSite.css")" rel="stylesheet" type="text/css" />
<![endif]-->
<!--[if gt IE 8]>
<link href="#Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<style type="text/css">
.gradient {
filter:none;
}
</style>
<![endif]-->
In my deprecated.css file I have the following:
#main {
background:url('/Images/iecollage.png');
background-repeat:no-repeat;
width:100px;
}
In my site.css, I have this comparable code for the same ID tag:
#main {
background:url('/Images/collage.png');
background-repeat:no-repeat;
background-size:920px;
width:100px;
}
I had to use 2 differently sized images and attribute definitions to correct the way the browsers interpreted the Markup. I am comparing the results using IE8 and Chrome.
When I launch the site, the home pages reflect the appropriate corresponding images and renders everything as expected.
My problem occurs when I navigate to another page which resides outside the Home directory (if that really makes any difference with respect to the issue).
The page has the following in-line code:
<div id="spotlight" style="position:relative;left:-50px; top:2px; height:820px;margin: 0;width:650px;">
In my Site.css file I have the ID styled as such:
#spotlight {
background:url('/Images/orange_spotlights3.jpg');
background-repeat:no-repeat;
-khtml-opacity:.60;
-moz-opacity:.60;
-ms-filter:"alpha(opacity=80)";
filter:alpha(opacity=80);
filter: progid:DXImageTransform.Microsoft.Alpha(opacity=0.6);
opacity:.60;
width:100px;
}
In the Deprecated.css the style is:
#spotlight {
background:url('/Images/orange_spotlights3.jpg') no-repeat;
}
In Chrome, the style gets loaded from the imported stylesheet. But in IE8 I get a blank area where the image should be loaded.
The quirky behavior I noted is that if I were to remove the following lines from the Site.css file, then both Chrome and IE8 will render the image but I loose the transparency effect in Chrome which is not the intent of separating the ID's to different stylesheets.
-ms-filter:"alpha(opacity=80)";
filter:alpha(opacity=80);
filter: progid:DXImageTransform.Microsoft.Alpha(opacity=0.6);
opacity:.60;
Its as if the 2 stylesheets are confusing the browsers or something.
Any explanation would be greatly appreciated.
As it stands, I am thinking of simply scrapping any support at all for IE8 because its getting to be too much of a bother trying to create 2 different accomodations to render the elements.
If you're using MVC it may be a problem with the absolute path which is kind of what it sounds like is happening. (Try pulling up your developer tools in Chrome or FF and check out the console while doing a page reload see if you get a 404 on the image GET request)
You can try something like ../../Images/orange_spotlights3.jpg where each ../ is one folder level up. You could also look at using a helper like #Url.Content("/images/orange_spotlight3.jpg") or try the absolute path all together.
Ok, after doing some blundering with the stylesheets I managed to get both to play together. What I ended up doing was retaining the comments for all the previously mentioned lines in the
Chrome stylesheet except for opacity:.60
So my stylesheet that will be used to support all other browsers other than IE8 now looks like this:
#spotlight {
background:url('/Images/orange_spotlights3.jpg');
background-repeat:no-repeat;
opacity:.60;
width:100px;
}
The other stylesheet for IE8 remained as is and both pages render the image appropriately according to their assigned stylesheets.
Apparently the following attributes don't work well in IE8 and can obviously cause problems:
-khtml-opacity:.60;
-moz-opacity:.60;
-ms-filter:"alpha(opacity=80)";
filter:alpha(opacity=80);
filter: progid:DXImageTransform.Microsoft.Alpha(opacity=0.6);
I have tested this using Firefox, Chrome and IE8. I have not seen if there are issues with any other browsers but I would imagine this should work with Safari as well.
What I still have no explanation for is why those elements affected IE8 browser when they clearly did not exist in its assigned stylesheet.
In the next revision of this site, I will definitely drop support for IE8 altogether. As much as I'd like to make it available to users having out-dated versions of IE 8 and earlier, its just added labor to try to keep up a dead horse. :-)
My page is at http://jerswebempire.com/ovrtur/index.php
The page displays nearly perfectly in all browsers except IE8. In IE8, floated divs have incorrect margins. For example, you'll see the search bar at the top is sitting underneath the nav. However, if you open the page in Chrome or Firefox or IE9, it's displaying in the correct spot.
What am I doing wrong?! I can't seem to find a fix.
Also, the box for Latest Video is in two columns in all browsers but IE8. It's similar to the above problem where there is a left margin added that shouldn't be there.
The page was built with Bootstrap.
Any help would be appreciated.
Use ie conditionals between your index
<html> </html>
add a class to for the 'ie 8 only' margins like the html boilerplate does.
Load a custom ie 8 only stylesheet and play with the margin problem there like this:
<!--[if IE 8]><link rel="stylesheet" type="text/css" href="ie8-only.css" /> <![endif]-->
Or load a class where you need it.
<!--[if IE 8]><html class="ie8 lt-ie9"> <![endif]-->
Apply the ie conditional class to whatever you need.
<div class="floatedDiv ie8"
CSS
.ie8 { margin:0px; }
I can't debug on ie8 but I searched and found that there is in fact a negative margin bug on ie7/8.
They recommend using
zoom:1, position: relative
as a workaround.
Are unused CSS images downloaded by the browser or ignored?
Eg. in CSS rules which don't match any elements.
.nothingHasThisClass{background:url(hugefile.png);}
Or would this be browser-dependant?
This would be browser dependent, since it's how they decide to implement the spec, however in a quick test here:
Chrome: Doesn't
FireFox: Doesn't
Safari: Doesn't
IE8: Doesn't
IE7: Doesn't
IE6: Unknown (Can someone test and comment?)
No, they are not downloaded, not at least in Firefox, IE8 and Chrome.
An easy way to test this:
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
.nonexistent {
background: url('index.php?foo');
}
</style>
</head>
<body>
<?php if(isset($_GET['foo'])) {
file_put_contents('test.txt', $_SERVER['HTTP_USER_AGENT']);
} ?>
</body>
</html>
If test.txt is populated with the browser's user agent, then the image is downloaded. This was not the case in any of my tests.
A quick test proved it.
<!DOCTYPE html>
<html>
<head>
<title></title>
<style type="text/css"><!--
.hasnothing{background-image:url(http://25.media.tumblr.com/tumblr_ky7aakqvH01qatluqo1_400.jpg);}
.hassomething{background-image:url(http://27.media.tumblr.com/tumblr_kxytwr7YzH1qajh4xo1_500.png);}
--></style>
</head><body>
<div class="hassomething"></div>
</body></html>
The 2nd image, tumblr_kxytwr7YzH1qajh4xo1_500.png, was downloaded but not the other one. This was proven true in Chrome (Developer tools) and Firefox (Firebug).
Firefox and Chrome (Ubuntu 9.10) don't download images for classes/ids that aren't applied in the DOM.
This may be both platform and browser dependant, though.
Sometimes, it depends just exactly what "unused" means. Different browsers define it differently. For example, in Firefox, styles applied to the <noscript> tag are deemed "unused" and thusly, any images won't be downloaded.
Chrome 26 (possibly all of them, not sure), does download CSS images if they are applied to the <noscript> element, even when JS is enabled. (It isn't immediately clear to me why though, perhaps this is a bug?).
It does not download CSS images applied to elements within the <noscript> element, though. (this is expected behaviour, of course).
Example:
CSS:
noscript { background-image: url('always.png') 0 0 repeat; }
noscript p ( background-image: url('nojsonly.png') 0 0 repeat; }
HTML:
<noscript>The CSS background image of this NOSCRIPT-element will always be downloaded in Chrome. Will not be downloaded in Firefox</noscript>
<noscript><p>The CSS background image of this P-element won't be downloaded in Chrome or other browsers, unless JS is disabled</p></noscript>
In this case, if the user has JS-enabled, both always.png and otherbg.png are downloaded in Chrome. If the user does not have JS enabled, then only nojsonly.png is downloaded in Chrome.
I use this technique for measuring traffic-levels from non-JS-enabled users, as Google Analytics fails us here. I prefer using the background CSS image rather than a normal <img...> tag, because I'm working under the (untested) theory that bots are less likely to grab a CSS image than a <img...> image, leaving more accurate counts for the human-visitors.
Almost all browsers do lazy-loading. If an image is not required, it does not download. Use firebug (add-on in Firefox/Chrome) to see load time for resources.
Interestingly, though, Chrome (at least) will download unused.png in the following example:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>test</title>
<style type="text/css">
.unused {
background: url(unused.png) no-repeat;
}
.used {
background: url(used.png);
}
</style>
</head>
<body>
<div class="unused used">
hello world
</div>
</body>
</html>
