internet explorer not anti aliasing rotated image - html

I have a div with a background image that I am rotating. Below is my css rules to rotate it:
#services_parallax {
-webkit-transform:rotate(3.1deg); /* Webkit */
transform: rotate(3.1deg); /* firefox & IE9+ */
/* IE7 & 8 */ filter: progid:DXImageTransform.Microsoft.Matrix(M11=0.998537, M12=-0.054079, M21=0.054079, M22=0.998537, sizingMethod='auto expand');
}
The problem is in IE the edges of the image are very blocky and jagged instead of being smooth lines and don't appear to be antialiased. Does anyone know a fix for this? It was doing it in chrome until I applied the fix for it by applying -webkit-backface-visibility: hidden; which worked great for chrome, I just need a similar fix for IE if one exists.
To replicate this issue paste the following into an HTML file and look at it in IE:
<style type="text/css">
#services_parallax { -webkit-transform:rotate(3.1deg); /* Webkit */
transform: rotate(3.1deg); /* firefox & IE9+ */
/* IE7 & 8 */ filter: progid:DXImageTransform.Microsoft.Matrix(M11=0.998537, M12=-0.054079, M21=0.054079, M22=0.998537, sizingMethod='auto expand');
background: url(http://img.netcarshow.com/Pagani-Zonda_R_2009_1600x1200_wallpaper_01.jpg) center center;
background-size:100% auto;
height:100px;
width:700px;
margin-top:50px;
margin-left:50px;
}
</style>
<div id="services_parallax"></div>

Anti-aliasing don't work on large images if there are height and width forced with CSS (IE11, 10 and 9). I've make some (very) approximate tests and I deduct anti-aliasing works under 1000px.
I'm still looking for an official source for this issue.

#geoffs3310, I feel your pain.
I have found this is still an issue with IE11, and some other browsers (Safari on iPad and on Chrome and the default browser on Samsung Galaxy Tab A). To work around this I whacked a dark background-color on the element containing the background-image. I don't know why, but it appears to do the trick, e.g.
background-color: black;
And in case anyone else reads this post, allow me to put forward a few other fixes I found in dealing with the various issues arising from skewing content. Note, these are all applied to the transformed container element.
Eliminates the jagginess buttons get after skew rotations are applied (kudos):
transform-style: preserve-3d;
Eliminate blurry where <canvas> has been used (kudos to Zoltan). Note, if there are other transforms on the element declare them on separate lines rather than shorthand (from memory this was to work around a similar Safari issue):
transform: perspective(0);
And another fix—though my documentation lacks what it fixes, I think it was to do with janky or blurry content in IE—try:
outline: 1px solid transparent;

To get round this issue i used box shadows which seemed to work and make the edges smooth

Background-size issue in IE and Google Chrome

I am using background-size on Chrome and found out it is CSS3 which is not supported in old versions of IE. Hence I have gone through some posts and someone recommended to use this filter:
progid:DXImageTransform.Microsoft.AlphaImageLoader
HTML:
<span class="num_blue_small small"><span class="numberText">4</span></span>
CSS:
.num_blue_small
{
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='/images/num_blue_small.png',
sizingMethod='scale');
-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='/images/num_blue_small.png', sizingMethod='scale')";
}
.small
{
display: inline-block;
height: 35px;
width: 35px;
text-align: center;
vertical-align: middle;
line-height: 35px;
}
.numberText
{
color: White;
}
By implementing the "filter", it works perfectly in IE7; however, it turns invisible in Google Chrome.
If I include background: url(/images/num_blue_ssc.png) no-repeat; in .num_blue_small CSS class, it will work fine in Chrome but IE 7 will show 2 same images with different sizes.
What should I do to get it fixed?
you could try the background-size polyfill
An IE behavior adding support for background-size to IE8. of Louis Remi
Progressive Enhancement is the mantra I live by. It means "Have fun
with CSS3 and don't worry about IE8 users; they'll never notice
they're missing out on your gorgeous text-shadows and gradients,
anyway".
All was well until I discovered the elegance of background-size:
cover; and background-size: contain;. The first one, for instance,
allows an image to completely cover a background, without having to
send a 1920x1080 background image down the pipes.
Unfortunately, they don't degrade gracefully: websites would likely
appear broken to IE8 users
They offer that feature:
correct position and size of the background image
updated position and size on browser resize
updated image, position and size when the background-image is modified
but seems they have some limitation:
multiple backgrounds (although the :after trick can still be used)
4 values syntax of background-position
any repeat value in background-repeat
non-default values of background-[clip/origin/attachment/scroll]
resizing the background when the dimensions of the element change

Text overflowing out of div using transform: rotate(xdeg)

Using the css attribute transform: rotate(); works fine but when using it under horizontally oriented text it displayed outside of the div but I want it to display it within. I tried a lot with the display, position, left, top, float etc. attribute but nothing worked. Any ideas?
Here is the css-code for the vertical text:
width:130px;
height:50px;
-ms-transform:rotate(270deg); /* IE 9 */
-moz-transform:rotate(270deg); /* Firefox */
-webkit-transform:rotate(270deg); /* Safari and Chrome */
-o-transform:rotate(270deg); /* Opera */
Here is the example to try:
http://jsfiddle.net/ty6Zj/
You should use transform-origin property for that
transform-origin: 40px 20px;
Demo
Note: You've used all proprietary declarations for transform, should use a standard one as well..
transform:rotate(270deg);
Also, make sure you have this at the end of the proprietary properties...

IE8 rotate filter rotates div but not text

I'm currently trying to rotate text on all browsers incl. ie8+. I have set up my transforms for all the other browsers, but when it comes to IE8, I can only get the box to rotate, the text will not rotate with it.
see here:
https://dl.dropboxusercontent.com/u/106547/rotate/rotate.html
the markup:
<div id='container' class='container'>
<p class='rotated'>
My view has been loaded
</p>
text
</div>
the style:
regular -
.rotated{
display: block;
position: relative;
/* Safari */
-webkit-transform: rotate(-90deg);
/* Firefox */
-moz-transform: rotate(-90deg);
/* IE */
-ms-transform: rotate(-90deg);
/* Opera */
-o-transform: rotate(-90deg);
transform: rotate(-90deg);
}
and the IE8 conditional
<!--[if lt IE 9]>
<style type="text/css">
.rotated, .container{
zoom:1;
-ms-filter: "progid:DXImageTransform.Microsoft.BasicImage(rotation=3)";
filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=3);
}
</style>
<![endif]-->
as you can see here, the div/paragraph tags are rotated, but the text is staying horizontal:
I've been poking away at this for a while and can't seem to figure out why it isn't rotating. I'm not worried about the rotation position at the moment, I'm just trying to get it to rotate. Any ideas what is wrong?
Thanks.
for older IE, you should look after writing-mode to rotate entire box :)
http://msdn.microsoft.com/en-us/library/ie/ms531187%28v=vs.85%29.aspx
Your IE8 style uses the following selector .rotated, .container, whereas your normal style only rotates .rotated.
This is likely to be the root cause of the problem: the IE8 style is telling the browser to try to rotate both the container and the rotated elements. Since one is inside the other, this means that it will be trying to rotate the inner element twice.
In theory, this would mean that it would end up being upside-down, but we're dealing with IE's activeXfilter` styles here, and they are known blow up when you combine them, so given that I can understand why it would be showing the text un-rotated.
If you're doing a lot of rotating stuff in old IE, you might want to also know about the CSS Sandpaper library. This is a small Javascript polyfill lib that adds support for (near-) standard transform CSS to old IE versions. Using this makes life a lot easier as you can use the same syntax for all browsers, and not have to worry about the ugly filter styles.
Are you working local? Filters for Internet Explorer are only working online.

Transparent background color, but not transparent text in IE 6 and 7

I tried to follow the advices in CSS: semi-transparent background, but not text. I'm happy of the results in Firefox, Safari, Opera and Chrome. With these browsers I obtain a result similar to the one below, where you can see the background in transparency under the header. However, I've problems with IE.
You should click here to see the jsfiddle.
In IE8 is OK, but in IE6/7 there is no colored band at all. Anyone knows how to fix it?
In div.header:
Remove:
background-color: #0a5787;
background: transparent;
Add:
background: none;
zoom: 1;
Change:
/* For IE 5.5-7 */
filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#900a5787, endColorstr=#900a5787);
/* For IE 8 */
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#900a5787, endColorstr=#900a5787)";
This works on IE7 when I test it and in theory I'm sure it should work in IE6, but on my emulator it is not working.

HTML/CSS IE Not displaying my dropdown menu z-index related

For some reason I cannot display the dropdown menu on IE when I add a z-index in the header of any number. When I remove it, it works. However the dropdown then appears behind the container and content in Firefox and Chrome. So either I take it out or leave it in, I cant seem to satisfy all browsers. So i tried making a separate IE stylesheet without the z-index but that doesnt work either. I know the separate IE CSS is working because I changed the backgrounds but it uses the dropdown menu in the master stylesheet.
Website is www.stingrayimages.ca
Thank you for your help
Edit: So lets just say i got it all to work on IE since its always IE that gives the problems. But now the dropdown menu appears behind the content on other browsers like firefox and chrome. All i did was remove the z-index in the #head div. Anyway to fix the dropdown menu without adding z-index to the head div?
Edit: I got the dropdown to work on IE9 firefox and chrome. Not IE 6, it just blew up.
#head {
position:relative;
height: 140px;
width: 100%;
background: #FFF;
filter:alpha(opacity=93);
padding-top:20px;
/* CSS3 standard */
opacity:0.93;
-moz-box-shadow: 0 0 5px black;
-webkit-box-shadow: 0 0 5px black;
box-shadow: 0 0 5px black;
z-index:1;
}
OK so I had a look and there's good news and bad ;)
the opacity filter in the #head div means that overflow: hidden is being triggered, which is why no menus (it's the unfortunate side effect of filters and overflow I'm afraid).. remove that and you can have your z-index which you need anyway
next to get the transparency (opacity) for your dropdowns you can just use rgba(255,255,255,0.9) on the #nav ul li ul rule instead of #fff; (though leave #fff before that rule for fallback for browsers that can't do rgba() yet.. read more!)
That's nearly everyone happy - now you can also do rgba() transparency for IE using the gradient filter..
so the rule I landed up with looked like this (in an IE conditional comment):
#nav ul li ul {
zoom: 1;
background: transparent;
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#E5FFFFFF,endColorstr=#E5FFFFFF)"; /* IE8 */
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#E5FFFFFF,endColorstr=#E5FFFFFF); /* IE6 & 7 */
/* behavior: url(PIE.htc);*/ /* yuk filter */
}
and I thought it would be good to go..
BUT the Bad News
the behavior is commented out because you can only have one or the other, transparency or rounded corners, :( apparently
I didn't do too much research though so YMMV
I also noticed a problem or three in IE7, not sure if you want to support that but in case you do.. or want to check my final code which got it to this stage I pasted it in PasteBin
that code replaces your main CSS - the #head rule and whole /*navigation*/ section
Update: more good news and a little bad!
you can have the transparency and the rounded corners thanks to CSS3 PIE's own -pie-background property, but not the box shadow as well, the way PIE deals with box shadow means it fills the div instead of just drawing on the outside so the -pie-background reading of the rgba background is transparent but shows the grey color used for the shadow!
My solution:
I added a border to make up for loss of box-shadow, it's not looking too bad, and it's working across IE's ;)
here's an update to the I conditional comment above:
<!--[if lte IE 9]>
<style type="text/css" media="screen">
#nav ul li ul {
box-shadow: none;
-pie-background: rgba(255,255,255,0.9);
border: 3px double #eee;
border-width: 0 3px 3px 3px;
behavior: url(PIE.htc); /* yuk filter */
}
</style>
<![endif]-->
I am not sure which version of IE you are having a problem with but I tried in IE6 and IE7 and the menu system is completely broken. I don't have IE8, 9 or 10 here to test but I'll take a guess at a solution nonetheless!
If you add a z-index and position to the #container as well, it should solve your problem. z-index only applies to positioned elements.
#container {
position:relative;
z-index:0;
}
It is also worth reading Overlapping and z-index, which summarises the properties and also describes the problems when using z-index and IE.
Edit: Wow, I did not realise what was wrong until I found a machine with IE8 on it. I think you have misunderstood the standard CSS and IE specific CSS principle slightly. The IE specific CSS file(s) should only contain the properties that are different to the standard ones. Your ie-style.css file contains duplicates of all the rules and is being included for all versions of IE. IE8 is much more standards compliant than IE6/7 and you should rarely have to override CSS for that version.
So IE will have multiple copies of the same style being applied. Under normal circumstances most browsers can cope with this duplication, however one of the duplicates is the IE specific filter property.
You have filter:alpha(opacity=93); in both style.css and ie-style.css even though it should really only belong in an IE6/7 CSS file as IE8 filters work differently. If you remove the filter from both stylesheets then the menu correctly displays in IE8.
If you need the opacity to work in IE6 or IE7, I suggest creating a specific CSS file for those browsers and using conditional comments to include it just for those versions.
Have a look at this solution : http://webdemar.com/webdesign/superfish-jquery-menu-ie-z-index-bug/
Another solution that I used already is quite easy, but a pain in the *. You must all the parent container a specific lower z-index value than the one you want to show on top of the others.
Like so :
<parent>//z-index 1
<child>//zindex 2
<yourdropdown>//z-index3
Update 1
The menu didn't show correctly in my chrome so I fixed the #head z-index to 80 and it did way better. Do the following to get the layout the same in IE and Chrome and Firefox. Watch out though, I only tested those change on the homepage.
Add this to the .conbox class :
.conbox {
position:relative;
}
Place the logo correctly
#logo {
position:absolute;
left:0px;
top:0px;
}
Remove the #nav positioning
#nav {
margin-top:80px;
z-index:3;
}
The problem is, I can't even see any effect on the menu mouseover in IE!!
Setting z-index: -1 for elements that menu overlays and z index of men div resolved this problem for me.
#bodyWrapper
{
background: none repeat scroll 0 0 #E4F7FE;
overflow: hidden;
position: relative;
width: 100%;
padding: 0 0 60px;
z-index: -1;
}
