Is there any way I can make a :hover opacity cross browser? - css

I'm trying to get this effect to work in IE8, but can't seem to find a good solution.
http://jsfiddle.net/aarhG/2/
Have any ideas?
I've tried adding:
.image {
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";}
.box:hover .image {
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";}
but that doesn't seem to work on hover...

if you don't have a correct doc-type
The problem will most likely be down to that :hover is not supported in IE8 outside of a tags when using certain doc-types.
Is :hover:after supported in IE8?

Hover effects not working with IE8
Generally if I wanted a hover effect in an older browser I would use an a tag to wrap the element:
<img />
And then target using the following:
a:hover img { opacity: 0.5; filter: Alpha(opacity=50); }
You'll probably find that it isn't the opacity causing the problem, if you switched to changing another css property onhover — say border — it still wouldn't work without using a a tag.
after a further look
It seems that your doctype is ok, so the above note is not the issue. However it does seem that you are utilising html5 tags, which will also cause you issues in IE8. A fix for this is as follows.
Older versions of Internet Explorer do not fully recognise the new html5 tags, however if you create a singular instance of the tags you wish to use in JavaScript, IE starts believing the tags are real. This is generally part of what a html5.js shim would do. It is also a good idea to make sure these new tags are displaying as block in your css.
<!DOCTYPE html>
<html>
<head>
<meta charset=UTF-8">
<title> Opacity IE8 </title>
<style>
.container {
display: block;
position: relative;
}
.container .box {
display: block;
width: 100px;
height: 100px;
background-color: red;
position: absolute;
opacity: 0;
filter: Alpha(opacity=0);
}
.container:hover .box {
opacity: 1;
filter: Alpha(opacity=100);
}
</style>
<script>
document.createElement('figure');
document.createElement('figcaption');
</script>
</head>
<body>
<figure class="container">
hover me
<figcaption class="box">
<ul class="list">
<li>1</li>
<li>2</li>
<li>3</li>
</ul>
</figcaption>
</figure>
</body>
</html>

This is what I use in my sites and I have never had any problems with any browser, including older versions of IE: { filter: Alpha(opacity=80); opacity: .8; -moz-opacity: .8; }.

Why hyphens don't work with inner <span>?

I'm trying to get hyphens working on text that has <span> elements inside for highlighting. This seems to break the hyphen algorithm. Is there any way to fix the behaviour so that hyphens are placed the same as without <span> elements?
I'm not asking about a workaround like ­
The Code (sandbox: https://codepen.io/anon/pen/ayzxpM):
.limit {
max-width: 50px;
hyphens: auto;
font-size: 20px;
background-color: #eee;
}
span {
color: red;
}
<div class="limit">
<p>
Appletreefruitthing
</p>
<p>
Apple<span>tree</span>fruitthing
</p>
</div>
Using the lang attribute
Adding the lang attribute as Vadim Ovchinnikov suggested (<div class="limit" lang="en">) can lead better results on some platform/browser combinations. On Firefox 54, Windows 10 this is the result:
But even that seems buggy. The hyphen should be black in my opinon and the hyphen algorithm seems to miss the chance to make a line break between "fruit" and "tree", also completly ignoring the max-width that is set for the container.
Actually, it does work with spans, in a number of browsers. You just used a word that is not recognized. Here's an example with a normal English word, that works in IE (should also work in Edge) and FF on Win7:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, user-scalable=yes, initial-scale=1">
<title>Demo</title>
<style>
div {
max-width: 50px;
-webkit-hyphens: auto;
-moz-hyphens: auto;
-ms-hyphens: auto;
hyphens: auto;
font-size: 20px;
background-color: #eee;
}
span {
color: red;
}
</style>
</head>
<body>
<div>
<p>Incomprehensibilities</p>
<p>Incom<span>pre</span>hensibilities</p>
</div>
</body>
</html>
It does not work in Chrome on Win, because that currently (June 2018) still does not support hyphens at all. It also does not work in any iOS browser. So you will have to use soft hyphens after all. But as you stated that you were curious about the mechanism, I thought it worthwhile to still post this answer.
Chrome has only partial support for hyphens property (only Mac and Android platforms), so you can't make it work on Windows.
I don't see any difference between span presence and absence in Firefox, IE and Edge (all on Windows) for this code.
To make it work there you'll need set lang for container and add vendor prefixes (for -ms-hyphens IE/Edge and -webkit-hyphens for Safari). Demo:
.limit {
max-width: 50px;
font-size: 20px;
/* Safari */
-webkit-hyphens: auto;
/* IE, Edge */
-ms-hyphens: auto;
hyphens: auto;
background-color: #eee;
}
span {
color: red;
}
<div class="limit" lang="en">
<p>
Appletreefruitthing
</p>
<p>
Apple<span>tree</span>fruitthing
</p>
</div>
To work in all browsers you may shouldn't use CSS hyphens property, just insert ­ manually where you want hyphens.
.limit {
max-width: 50px;
font-size: 20px;
background-color: #eee;
}
span {
color: red;
}
<div class="limit">
<p>
Apple­tree­fruitthing
</p>
<p>
Apple­<span>tree</span>­fruitthing
</p>
</div>
hyphens: manual
togteher with
­
might work
see documentation here
https://css-tricks.com/almanac/properties/h/hyphenate/
this code on codepen seems to work
<div class="limit">

CSS Top Padding in IE9

I have a CSS similar to the one below.
.ui-icon {
font-size: 6em;
height: 180px;
width: 180px;
}
.ui-icon .ui-icon-label {
padding-top: 15%;
}
The top padding doesn't display the text in IE9 (i.e. ui-icon-label).
HTML is also given below.
<div class="ui-icon-color ui-icon">
<div id="icon-1">
<i class="icon-cog"></i>
</div>
<div class="ui-icon-label">My Label</div>
</div>
But the same code works well in Chrome and Firefox. IE9 displays the ui-icon-label till the padding is 13.4%. Till the value, when I increase it gradually the text moves downwards a bit. Above that value it suddenly disappears. But For me 15% looks the best position to place the label. I went through different solutions provided in the suggest like 'clear:both' or using the W3C validator. But they didn't help.
FYI, the icon-cog class comes from font-awesome.
Have you considered using a IE9 targeted stylesheet with media queries to solve that issue?
<!--[if IE 9]>
<link rel="stylesheet" type="text/css" href="ie9.css" />
<![endif]-->
// In the CSS:
#media (max-width: ???px) {
.ui-icon .ui-icon-label {
padding-top: 30%;
}
}

CSS IE conditional background

I have a background that I would like to change depending on which browser the user if using. If the user is using IE7 or IE8 I would like to change the background to a totally different image.
Can this be achieved by editing the CSS below as it seems pointless to create a new stylesheet for one item.
Thanks in advance for any help.
.navigation{
background: url("images/navigation.png") no-repeat;
}
Pretty sure there's no way to do it without extra markup.
You could just do this in the HTML:
<!--[if gte IE7]>
<style type="text/css">
.navigation{
background: url("images/navigation.png") no-repeat;
}
</style>
<![endif]-->
Isn't exactly the sexiest bit of code I've ever written, but it does the job without adding a whole separate stylesheet file. Though you might as well give in and make an iehacks.css file.
This code should only select the background if you're using IE 7 or greater. Other ways of using conditional HTML can be found at http://css-tricks.com/132-how-to-create-an-ie-only-stylesheet/.
<!--[if gte IE 7]>
<style type="text/css">
.navigation{
background: url("images/navigation.png") no-repeat;
}
</style>
<![endif]-->
<body onload="setBG()">
<h1>Welcome to my page</h1>
<script>
function setBG(){
document.body.style.backgroundImage=((!!document.all || window.opera) ? 'w3bg.jpg : 'iebg.jpg') // delete the second ! and switch the jpgs
return
}
</script>
This means if the browser does not support document.all (which is supported only in IE4+) or is Opera then display the background iamge w3bg.jpg. If the browser does support document.all then display the background image iebg.jpg.
There is but keep in mind this is not valid CSS. Your best bet is to create the second stylesheet with a conditional statement.
IE7 will interpret this
*+html .navigation { background: url("images/navigation.png") no-repeat; }
IE8 will interpret this
#media \0screen {
.navigation { background: url("images/navigation2.png") no-repeat; }
}
.navigation{
background: url("images/navigation.png") no-repeat;
/*all browsers*/
}
*+html .navigation {
background: url("images/navigation_onlyIE7.png") no-repeat;
/*only IE7 valid css*/
}
#media \0screen { .navigation
background: url("images/navigation_onlyIE8.png") no-repeat;
/*only IE8 NOT valid css*/
}
I would probably use IE CSS hacks that target the element: http://paulirish.com/2009/browser-specific-css-hacks/. It eliminates the need to create a new style sheet.

IE 6 vs. position:fixed

position:fixed that doesn't work for Internet explorer 6. I can't really understand the fixes found on google. I need it to work in IE6, IE7, IE8 & FireFox 3.0.

Don't support IE6! The sooner people stop hacking sites about for IE6, the less traction it will have and the quicker it will die! Or, add this code after your first style block;
<!--[if IE 6]>
<style type="text/css">
#sidebar_right, #sidebar_left {
position:absolute; /* position fixed for IE6 */
top:expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px');
left:expression(0+((e=document.documentElement.scrollLeft)?e:document.body.scrollLeft)+'px');
}
</style>
<![endif]-->
The result isn't super-smooth, but it does work.
UPDATE
I wasn't too clear on how this should be used; simply add the id (or class) of any elements that have "position:fixed" to the declaration list at the start of the above block and they will behave themselves in IE6.
yes IE6 sucks. here's the hack...
_position: absolute;
_top: expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px');
that basically tells IE6 to keep it absolutely positioned in the top left even as it scrolls.
this should go under the rest of your css for the element so it over-rides it in IE6.
here it is for your left bar...
#leftBar {
position:fixed;
top:0;
left:0;
width:200px;
_position:absolute;
_top:expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px');
}
I just tested this on IETester's version of IE6 and it worked great and... No Jitter, Whoo!
Let say you have a element with a class of box for example...
.box {
position: fixed;
top: 0px;
left: 0px;
}
Replace the opening <HTML> tag with conditional IE statements...
<!--[if IE 6]> <html id="ie6"> <![endif]-->
and
<!--[if !IE]--> <html> <!--[endif]-->
Then like MatW & mitchbryson suggested use 'expression' to simulate position fixed.
Note: This code goes after the original element's styles in the CSS.
#ie6 .box {
position: absolute;
top: expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px');
left: expression(0+((e=document.documentElement.scrollLeft)?e:document.body.scrollLeft)+'px');
}
The problem is that on any page scroll the element will jitter, this is one way to compensate...
Note: This code goes at the top off your CSS or after your styled 'HTML { }' in your CSS.
#ie6 {
background-image:url(about:blank);
background-attachment:fixed;
}
According to Thomas Aylott # SubtleGradient.com ,
"... This forces the processing of the CSS before the page is redrawn. Since it’s processing the css again before redrawing, it’ll go ahead and process your css expressions before redrawing too. This gives you perfectly smooth position fixed elements!""
article link: http://subtlegradient.com/articles/2009/07/29/css_position_fixed_for_ie6.html
For example, all together...
<!--[if IE 6]> <html id="ie6"> <![endif]-->
<!--[if !IE]--> <html> <!--[endif]-->
<HEAD>
<STYLE>
#ie6 {
background-image:url(about:blank);
background-attachment:fixed;
}
.box {
position: fixed;
top: 0px;
left: 0px;
}
#ie6 .box {
position: absolute;
top: expression(0+((e=document.documentElement.scrollTop)?e:document.body.scrollTop)+'px');
left: expression(0+((e=document.documentElement.scrollLeft)?e:document.body.scrollLeft)+'px');
}
</STYLE>
</HEAD>
<BODY>
<div class="box"></div>
</BODY>

Found this solution which I tweaked ( Basically the lines I changed was: $('#sidebar_left').css('top',document.documentElement.scrollTop); ):
// Editing Instructions
// 1. Change '#your_div_id' to whatever the ID attribute of your DIV is
// 2. Change '175' to whatever the height of your header is, if you have no header, set to 0

window.onscroll = function()
{
if( window.XMLHttpRequest ) {
if (document.documentElement.scrollTop > 299 || self.pageYOffset > 299 && document.documentElement.scrollBottom > 100) {
$('#sidebar_left').css('top',document.documentElement.scrollTop);
$('#sidebar_right').css('top',document.documentElement.scrollTop);
} else if (document.documentElement.scrollTop < 299 || self.pageYOffset < 299) {
$('#sidebar_left').css('top','299px');
$('#sidebar_right').css('top','299px');
}
}
}
It jitters and looks bad, but work on all browsers including IE6.
I recently wrote a jQuery plugin to get position:fixed working in IE 6+. It doesn't jitter on scroll, it looks at capability (not user-agent), works in Internet Explorer 6, 7, 8.
If you use strict mode in IE7+ position:fixed will be honoured, but by default IE7+ operates in Quirks Mode. This plugin checks for browser capability, and if it doesn't honour position:fixed, then it implements the jQuery fix.
http://code.google.com/p/fixedposition/
Something like this may work for you:
$(document).ready(function(){
$("#chatForm").fixedPosition({
debug: true,
fixedTo: "bottom"
});
});
You may need to make some minor CSS adjustments to get it working for your code. I'm working on "offset" values as options as we speak.
It is possible to do it with CSS expression, but with some extra hack to get a smooth scrolling:
html, body {
_height: 100%;
_overflow: hidden
}
body {
_overflow-y: auto
}
#fixedElement {
position: fixed;
_position: absolute; / ie6 /
top: 0;
right: 0
}
