i have just downloaded dreamweaver cs5.5 and am trying to apply css3 to my page, however although my current css is working fine both in dreamweaver and other coders the new css3 is not being applied.
eg i am trying to apply border-radius, although it is showing up in my css list as i type it out (unlike microsoft expression 4, which is'nt although i believe it should), it is not being applied to the actual page.
i have also tried using box-shadow, and linear-gradient, both unsuccessfully which made me believe that it is a css3 issue.
could it be something like setting up dreamweaver to accept css3, (ticking/unticking something in settings).
i am a beginner, any help would be appreciated and also i have looked it up before submitting q, but it seems not much info on css3 and especially css3 with dreamweaver.
thanks in advance
Did you make sure to include properties for all browsers? also, can we see your css?
Cross compatible linear gradient needs to look like this:
linear-gradient(bottom, rgb(48,54,48) 0%, rgb(54,61,54) 100%);
-o-linear-gradient(bottom, rgb(48,54,48) 0%, rgb(54,61,54) 100%); /*opera*/
-moz-linear-gradient(bottom, rgb(48,54,48) 0%, rgb(54,61,54) 100%);/*mozilla*/
-webkit-linear-gradient(bottom, rgb(48,54,48) 0%, rgb(54,61,54) 100%);/*chrome*/
-ms-linear-gradient(bottom, rgb(48,54,48) 0%, rgb(54,61,54) 100%);/*IE*/
Please see what browser you are using Internet explorer 8 and below may not support the css3 newly introduced styles.check it in a browser like chrome. Also refer to the answer from #rfinz you can see how he does it for different browsers. You probably have to work along the same lines

I am working on app which platform is targeted to modern browsers but exceptionally its required to run on IE9 which doesn't supports CSS3 gradient. Can anyone please suggest any alternative (except SVG) would benefit me greatly.
.GRAD_LINEAR(#start:#EEA611; #end:#E3EE11) {
background: #start;
background-image:-webkit-gradient(linear, left top, left bottom, from(#start), to(#end));
background-image:-webkit-linear-gradient(top, #start, #end);
background-image:-moz-linear-gradient(top, #start, #end);
background-image:-o-linear-gradient(top, #start, #end);
background-image:linear-gradient(to bottom, #start, #end);
//Your suggestion...
}
There are several ways you can achieve this.
Try ColorZilla Gradient Editor. Since Microsoft provides its own filters, something like
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#1e5799', endColorstr='#7db9e8',GradientType=0 ); /* IE6-9 */
will be fine for you.
Use an HTC file, something like CSS3 PIE which adds the necessary functionality to older versions of IE to emulate modern CSS3 features. It has its own pros and cons but worth a shot.
The next, least recommended, way of doing it will be using images. But then you will increase the number of HTTP Requests your application makes. Also if an image fails to load, your element might look ugly.
You can make gradients work in IE9 Check this -- Colorzilla

Why does the background and the menu buttons shape not display correctly in IE versions < 11? The page looks ok in Chrome, IE 11, etc.

It's possible that you're using CSS3 properties, those properties not have support in all versions of the browsers and in some cases need for special prefixers.
Check this link http://www.w3schools.com/cssref/css3_browsersupport.asp
For example your background made with css has this prefixes:
-webkit-linear-gradient
-moz-linear-gradient
-ms-linear-gradient
-o-linear-gradient
Review this here -webkit-linear-gradient(
here is your background definition for #main:
background: -moz-linear-gradient(center top , #DBDBDB, #FFFFFF) repeat scroll 0 0 rgba(0, 0, 0, 0);
IE don't understand the -moz prefix
you need the complete definition in order to support the other browser families, e.g.:
background: rgb(69,72,77);
background: -moz-linear-gradient(top, rgba(69,72,77,1) 0%, rgba(0,0,0,1) 100%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,rgba(69,72,77,1)), color-stop(100%,rgba(0,0,0,1)));
background: -webkit-linear-gradient(top, rgba(69,72,77,1) 0%,rgba(0,0,0,1) 100%);
background: -o-linear-gradient(top, rgba(69,72,77,1) 0%,rgba(0,0,0,1) 100%);
background: -ms-linear-gradient(top, rgba(69,72,77,1) 0%,rgba(0,0,0,1) 100%);
background: linear-gradient(to bottom, rgba(69,72,77,1) 0%,rgba(0,0,0,1) 100%);

Websites breaking in one type but working in another is usually related to illegal usage of HTML or CSS. Some browser allow you to do something you're not really allowed to do meanwhile others don't.
Use the w3.org HTML validation service to find errors on your website (HTML), you can take look at your results here, you'll see that you got some errors on your website.
You can also use the w3.org CSS validation service to find errors on your website (CSS), you can take a look at your results here.
You will see that your website has over 100 errors in the CSS; this is probably the cause of your problem. Fix your HTML and CSS and your website should render just fine.
Also check available tables to see which CSS and HTML attributes work on all browsers, some don't, yet.
You could use the Mozilla Developer Network to check the compatibility of browsers. Let's, for example check the -moz- attribute you're using in your CSS;
Browser Lowest version Support of
Internet Explorer --- ---
Firefox (Gecko) 1.0 (1.0) -moz-appearance Not fully supported
Opera (Presto) --- ---
Safari | Chrome | WebKit 3.0 | 1.0 | 522 -webkit-appearance
You'll see that you'll have problems on certain browsers, like Internet Explorer.
You can also check the table here.
Note that compatibility issues are mainly related to HTML5 and CSS3, which are the newest versions.
I got this background-color here
-moz-linear-gradient(center top , #0043A1 0%, #0043A1 100%) repeat scroll 0 0 transparent;
but it will not work in google chrome, any ideas on how to fix it?
Thanks,
J
Replace with
linear-gradient(center top , #0043A1 0%, #0043A1 100%) repeat scroll 0 0 transparent;
-moz-* css properties are specific to mozilla. They're useful while a property isn't normalized but now (with CSS3) you may use the standardized linear-gradient.
Even the Mozilla documentation now documents linear-gradient.
Use this for Chrome and Safari browsers:
-webkit-linear-gradient
And use this for Mozilla (Firefox):
-moz-linear-gradient
You might like the site CSS3Please! which lets you see how to apply all these various properties, and generates the code for all browsers (even Opera, which most people often forget but which they really really shouldn't. So sayeth a diehard Opera user.) There's also ColorZilla's Gradient Generator, which I've found to be a little less intuitive...but it does generate the CSS styledefs as well.
How do I use a CSS linear gradient with Netscape?
I am trying this code:
#gr {
background: -webkit-gradient(linear, left top, left bottom, from(#ffffff), to(#000));
background: -moz-linear-gradient(top, #ffffff, #000);
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffffff', endColorstr='#000');
-ms-filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffffff', endColorstr='#000');
}
It works with IE, Firefox, and Chrome but it does not work with Netscape.
Netscape Navigator 9, last updated between 2006 and 2008 as a Firefox derivative, does not offer any real support for CSS beyond a large subset of the CSS2.1 spec. It does not support CSS3 gradients, or most any other CSS3 feature.
Netscape Navigator/Communicator 4.x and older don't have a lot of CSS support at all.
If you really need a gradient, you're better off using a background image. That's the traditional, tried and tested method designers have been using for the past 10 years, with great cross-browser compatibility yet very little friction.
If you're trying to support Netscape only because you are a Netscape user, stop wasting your time. Switch to Firefox. No serious web designer uses Netscape anymore in this day and age.
Netscape is no longer supported and is very rarely used by anyone.
But if you still want to use a linear gradient on your site, you can create an image using Photoshop or any other graphic editor, and then use it as:
background-image: url('url-of-img.jpg');
I am a web developer, I recently looked at GMAIL's new LOGIN PAGE preview and there is a Sign In button, I was really excited about its UI. I did some surgery of Page's CSS and found some properties like:
**background-color: #4D90FE;
background-image: -webkit-gradient(linear,left top,left bottom,from(#4d90fe),to(#4787ed));
background-image: -webkit-linear-gradient(top,#4d90fe,#4787ed);
background-image: -moz-linear-gradient(top,#4d90fe,#4787ed);
background-image: -ms-linear-gradient(top,#4d90fe,#4787ed);
background-image: -o-linear-gradient(top,#4d90fe,#4787ed);
background-image: linear-gradient(top,#4d90fe,#4787ed);**
Now can anyone please tell me how can I maximize the page's optimization for all popular browsers using these kind of CSS extension properties. I mean is there any reference link for these extensions or some other good stuff.
Thanks.
You should use google to find such information, a lot of it has been around since early 2010.
but here are some examples of browser specific gradient codes:
.gradient-bg {
/* fallback/image non-cover color */
background-color: #1a82f7;
/* fallback image */
background-image: url(images/fallback-gradient.png);
/* Safari 4+, Chrome 1-9 */
background-image: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#2F2727), to(#1a82f7));
/* Safari 5.1+, Mobile Safari, Chrome 10+ */
background-image: -webkit-linear-gradient(top, #2F2727, #1a82f7);
/* Firefox 3.6+ */
background-image: -moz-linear-gradient(top, #2F2727, #1a82f7);
/* Opera 11.10+ */
background-image: -o-linear-gradient(top, #2F2727, #1a82f7);
}
Taken from here.
To find out which browser supports which selector has a lot to with testing.
If you just need cross-browser-gradients, use http://www.colorzilla.com/gradient-editor/ (supports also IE6-9).
To find out, which technique is supported by which browser http://caniuse.com is a good resource.
There is a pretty comprehensive list of Mozilla's CSS extensions (or simply things that haven't been fully standardized yet) here: https://developer.mozilla.org/en/CSS_Reference/Mozilla_Extensions
There is also an attempt to list all vendor-specific CSS properties under http://webdesign.about.com/od/css/a/css-extensions.htm but it is probably pretty incomplete and outdated - this area changes fast. In the end, you should better look at CSS3. Either a feature is already listed there which means that vendor prefixes will likely be dropped soon - or it is not and then using this feature in a production webpage isn't recommendable (its meaning might change significantly or browsers might stop supporting it altogether).
This is a list that I keep on me all times as a point of reference.
I hope this is of some use to you
