how can I make circle hover area what will work in IE7?
I made example with border-radius but it is not work for IE7: http://jsfiddle.net/y4xpQ
Thx
pretty sure you cant. The item is displayed as block(think of it as a brick). Not as circle. Sorry
but if you are after the border radius in ie7 look here - http://css3pie.com/
If you're targeting "old" browsers you might want to take a look at the also very old <area>.
Not the best element to use when it comes to accessibility (or standards compliance if you're after a circle made with shape="circ") but in this case i guess it gets the job done.

I am trying to animate lines going from left, right, top and bottom(lines should start from edges of the screen). Animation works fine in IE11 but not in Mozilla and Chrome. Other browsers I haven't tested. I used Adobe Illustrator to draw. http://codepen.io/Ljanmi/pen/WbyLWv
In Chrome and Mozilla(IE11 is fine and acts normal) if in Illustrator I set Object>Artboards>Fit To Artwork Bounds(minimizing Artboard size which I usually do when create or edit SVG) I get this result(even worse) - http://codepen.io/Ljanmi/pen/yyqVqz
I spent hours and hours trying to figure out on my own without success. I started topics on GSAP forum and CSS tricks forum(stackoverflow.com is limiting me to post only 2 links as a newcomer).
I used GSAP JS library for animating(generally very happy with GSAP) but animation behaves the same if I use CSS3 to animate. I concluded that it is not related to GSAP(viewbox size property seems to have little bit of effect here) , more likely to be related to SVG structure itself or browser compatibility or both. So I guess there must be some work around to make it work like I would like to. I most likely lack some SVG/HTML/CSS3 knowledge since I am not very experienced but trying to learn as much as I can. Thanks everybody for reading.
Add svg { overflow: visible } and it should work the same in all browsers (longer explanation below). If you want to see why the lines get clipped, add borders to the svg element.
Another way is to make sure the size of the svg matches what you want, e.g by using css.
All browsers except IE implemented hidden as the initial value for the overflow property for the <svg> element, as called for by the SVG 1.1 spec. SVG 2 has changed this for (outermost) inline svg elements, such that it requires what IE11 is currently doing. It will take some time before that gets changed in all browsers, so for now just add the overflow: visible rule and it should work correctly in all browsers.
I had some trouble with browsers still not showing the overflowed content for SVGs and found that this finally got past it:
svg:not(:root) {
overflow: visible !important;
}
I want to use transition effect on hover for IE 8 like in this example:
http://jsfiddle.net/evcL2/10/
According to this site (is working only on ie) that is possible (use trasntion option and fade effect) but I am not able to use it. Can someone help me a little bit with that script, for me is simportant to have that transition on hover only for background color.
Thank you.
IE8 doesn't support CSS3 transitions. You'll have to fake it using JavaScript tweens, or settle for IE9 support. IE8 users don't deserve nice looking websites anyway :-)
But if you're in the awkward position of being tasked with creating IE compatible stuff, take a look at this MSDN introduction to Filters and Transitions. It appears that even the IE specific transition filters require JavaScript to work, so you might as well go with the proper JavaScript solution of using jQuery.animate. With a small plugin it can animate colors. Here's an example on JSFiddle.
For some reason the website you suggested doesn't render properly in my browser. However, I think you may be attacking the problem wrongly. I would use jQuery's $.animate() function for this, as it is very cross browser and can animate gradual changes in many css properties.
I'm working on an example of a jQuery notification bar that you can see here: jQuery notification bar example
But for whatever reason the CSS I'm using to define transparency in IE 7 and 8 is not working. If you look at the example in IE 7/8, you will see that the transparency for the .png close button and the transparency for the "reopen" element does not work.
I've successfully defined an element's transparency in IE using this code before, but I can't figure out why it's not working in this example.
I thought I might have hit on something when I read this post, but after trying out the solutions mentioned with the hasLayout property I still didn't have any luck.
Any help would be greatly appreciated. Let me know if you need any additional details.
Thanks!
Wow somebody else just asked a question about this. In older versions of IE, you can't compose transparency from a PNG alpha channel with transparency from a CSS effect. As soon as you apply the style, it quits trying to do transparency from the image.
Yes, it's profoundly lame.
opacity: 0.50;
filter:alpha(opacity=50);
This fixes opacity for IE. Using 50% transparency as example value here.
As for the hellobar_close, give it a background-color and it should work. IE has poor support for transparency in .png images.
OK I believe that with the help of the answers provided above and some additional research on my own I have answered my question.
There are actually 2 parts to this problem:
1.) Transparency issues with the .png close button in IE - This part was answered by Pointy above. According to Pointy "The browser is incapable of managing the compositing of the transparent PNG concurrently with any opacity effect on the image. In other words, for any given pixel, you either get alpha channel effects from the PNG itself, or from an opacity filter, but not both." (Quote taken from his answer at IE7 and "jaggies" around layered PNGs (with jQuery))
What I want to happen is for the .png close button to be semi-transparent in it's normal state, and full opacity in its hover state, but apparently this is not possible to achieve in IE using only one single image and CSS transparency. So to get around this I'm just going to have to make a dual-state .png image to get a nice hover effect, rather than relying on CSS transparency to handle that component.
2.) Transparency issue with the "reopen" button - This button should be semi-transparent but did not work in IE. After doing some extensive research on my own I came across this post: jquery IE Fadein and Fadeout Opacity. woodstylee's answer in that post solved my problem.
Due to some weird IE bug that I don't completely understand, I need to declare the element's opacity using jQuery/javascript before any transition/fade effects are applied.
Obviously there is some kind of conflict with jQuery fades/transitions and CSS opacity in IE. If anyone else has some additional info on this subject please post!
When I updated my code with the following, I was able to successfully get my "reopen" button to appear semi-transparent in IE.
$('#hello_mini').css('filter', 'alpha(opacity=75)');
Note that the above line of code needs to be placed before this line:
$('#hello_mini').show('slow');
Also of note... this IE bug appears to only apply to the jQuery show() and hide() functions. When I switch the animation to slideUp() or slideDown() the transparency works fine without any additional javascript.
So bottom line... there is something weird going in with CSS transparency in IE when applied to elements animated through jQuery show() and hide()
If I find out anything else in my research I will post it here.
Here is a link to my updated example, which works in IE 7/8 now.
My designer believes this cannot be done, however it seems possible to me. (Although I have limited CSS experience). However, he also said the background couldn't be fixed, and stackoverflow has proved his wrong in the past; so I question his knowledge.
JQuery can be used if this cannot be done in pure CSS.
The top half will be a gradient that has full flexible to skew left, right, up, down without much distortion. The bottom half is an image that is ideally made for the 1280 x 1024 resolution (as this is the most popular browser display resolution). Then depending on the requirements needed it will sketch and skew to whatever size it needs. Still allowing all of the image to be seen.
The ration between the top half and bottom half is always 50% 50% independent of browser resolution.
I would also like if both the top and bottom parts are fixed.
In a perfect world (one without IE), id like to do this with css3 gradients and multiple backgrounds in 1 DIV. However, because IE9 isnt out yet, I think the best way to approach it would be 2 divs in a DIV container and using a PNG repeating background for the top div.
It should be noted I am going to use css3pie.com to allow some CSS3 for IE6-8 (but I dont want to rely on it, unless 100% proven)
Is this possible with just CSS? How would you do it?
If not possible with just CSS, is there a way I can get JavaScript/JQuery to aid?
I am thinking a base of 1280 x 1024 isn't the best idea because it seems to have an odd radio.
Edit 1
Oh yeah, I have a WIP too:
http://meyers.ipalaces.org/extra/
It looks good in 1280 x 1024...now its just getting the whole resizing of the top DIV to be 50% so the image is 50%.
I'd still like ALL of the water to be seen, because I like the look of the rocks at the bottom. However, I am open to alternative ideas that don't accomplish what I want 100%, but come close.
Edit 2
How about using the top gradient as the true CSS2 background and then just putting a <img> at the bottom of it to resize? Perhaps that will allow for CSS2 ability. I am reference some work-around techniques here: A list apart
Edit 3
I am still looking for results that work on IE6 and also don't cause Internet explorer to lag. I am setting a bounty of 50 to help attract more attention.
I have successfully came up with 2 ways to do this:
Method 1
Click here to view demo
Using CSS3 background-size I was able to set 2 div elements to on top of each other with min-height: 50% and then using background-size: 100% 50% they successfully accomplish what I am looking for.
This method was just a proof of concept, as IE6-8 does not support background-size, I didn't pursue tweaking this method perfectly. As it stands, it currently messes up when you scroll despite have background-attachment: fixed;. I ditched this CSS3 method in order to look for better methods using CSS tricks...
Method 2
Click here to view demo
Following the examples I found from A List Apart (Article | Example1 | Example2). I used Technique #2 from Example 1, and I was able to emulate what I wanted to do using just CSS2. (I am not 100% sure how or why this works, but it does)
Because I am also going to use CSS3PIE to give IE6-8 CSS3 the ability to do linear gradients, border-radius, and box-shadow; I opted to use a linear gradient instead of an image for the top background.
Problems
CSS2 Method from Technique #2, Example 1 does not work with IE6 Correctly
Creates excessive lag in all current Internet Explorers
It can be done with CSS only. No PIEs necessary. Just an IE6 bug and some filter magic.
Demo:
http://www.bundyo.org/test/FPB.html
Do this using raphaeljs. Create a background DIV that becomes a canvas, draw a rect to 50% of the page height (if using jquery then use $(window).resize() to monitor for a window resize and $(window).height() to get the 50% into pixels).
You can fill in the raphealjs rect with specifing it's fill value to something like fill: "90-#000000-#ffffff"
As for the image:
Place the image using raphealjs' image OR just embed it using HTML and update it's height-scale using jquery as mentioned above.
I've done something like this just recently using about 10 lines of code.
Also: Change your water.png, it's about 275kb, where as the next largest file on your page (the css) is like 1.5kb.
If you want to keep the horizon of the water at 50% on your screen, I would suggest a simpler method;
Create an image (probably about 1280 wide) in Photoshop of water on bottom and gradient on top. Fade the top gradient into a solid light blue(#68b for example). Fade the left, right and bottom of the image into the same solid color(#68b).
Set the background of your page as follows;
html {
background: #68b url(waterimage.png) center center no-repeat;
}
In your case, you'll probably want to apply the background to #wdth-100 instead of html, but it all depends on which element you want to put your background on.
All done. Let me know if that works for you.
I don't have a link to your top image, so i used the same image for top and bottom.
You should probably use a CSS solution for normal browsers and the JS for IE.
<script type='text/javascript'>
$(document).ready(function() {
wh=$(window).height();
ww=$(window).width();
if(wh%2) {
h1=Math.round(wh/2);
h2=Math.round(wh/2)-1;
} else {
h1=h2=wh/2;
}
img1=$("<IMG/>",{'src':'http://meyers.ipalaces.org/images/bottom-bg.jpg','id':'img1'} )
.css({'width':ww,'height':h1,'top':'0','left':'0','position':'absolute','z-index':'-100'});
img2=$("<IMG/>",{'src':'http://meyers.ipalaces.org/images/bottom-bg.jpg','id':'img2'} )
.css({'width':ww,'height':h2,'top':h1,'left':'0','position':'absolute','z-index':'-100'});
$(document.body).append(img1);
$(document.body).append(img2);
});
$(window).resize(function() {
wh=$(window).height();
ww=$(window).width();
if(wh%2) {
h1=Math.round(wh/2);
h2=Math.round(wh/2)-1;
} else {
h1=h2=wh/2;
}
$('#img1').css({'width':ww,'height':h1,'top':'0','left':'0'});
$('#img2').css({'width':ww,'height':h2,'top':h1,'left':'0'});
});
</script>
The pragmatic answer would seem to be to do it using multiple divs with their own background, all of which would be positioned absolutely and behind everything else using z-index.
I know that's not the clean markup solution with a single div with some magic CSS, but this is a tricky problem in pure CSS in any browser, and almost certainly impossible if you need to support IE6.
An even more pragmatic answer would be to say "I'll support IE6 as far as I can, but if it can't support my lovely background effect then that's just tough luck for anyone still using it".
I'm looking for a JavaScript library that can create round corners on div tags with a transparent background, such that the background colour/image of the parent element is visible at the rounded corners. For an example of rounded corners without a transparent background, have a look at the left menu on this page. Notice that the background of the parent element is not shown at the corners of the menu items.
I need this to work in IE7+ and FF3+ (ideally the other browsers too), and I'd prefer a JQuery plugin.
Does anyone have any good resources or plugins that would help?
JQuery Corner?
I tried 2 different JQuery corner-rounding plugins. This one didn't work in either FF or IE and this one only worked in FF.
However, I found a non-JQuery library that worked perfectly in both, DD_roundies.
It's got a lot of limitations... but the Transparent Background Corners plugin might work in your scenario.
If you can, however, I'd suggest actually doing all the rounding server-side with CSS. It's all just divs within divs, with different padding for the corner divs. It gets rid of the huge performance hit that Safari and IE will take if you have lots of rounding to do, and allows you to have the page still look stylish for your users who don't/can't enable javascript.
