I'm thinking about using the html <picture> element in a sliding carousel to optimise load times for a webpage.
I'm worried it does not have enough browser support though as I will need it to work in IE10.
Is there any other fallback method I can use for it to work in older browsers, or at least render something that will work.
You can use Picturefill to handle this https://github.com/scottjehl/picturefill
With it you an use the picture element as well as source sets and size attributes. It's been a while since I had to use this particular polyfill but in the past it worked fine.

I have a HTML5 video, working fine, and i'm happily smiling whenever i start my browser... However!
I know the Video tag isnt supported by some browsers, but i noticed there is a difference in support for video attributes/methods/whatever too. Is there a summary of this somewhere?
For example:
The poster attribute doesnt work in every browser, even if the vide DOES work!
I think its pretty worthless to just use an entire javascript library to take care of one attribute like poster, so how to take care of this?
Or am i completely wrong, and is IF video is supported, also every attribute supported the same way?
Please help me! :)
Thanks for all your advice,
WK
ps: I am using the video for everybody variant of the video. So thats working fine.
Is this the kind of thing your after?? click me.
Basically there is the following support for the HTML5 video tag:
Every modern browser that has support for HTML 5 supports <video>
meaning: IE9+, FF3.6+, Chrome, Opera, Safari
Internet Explorer 9 does not support the poster attribute. I believe
there is even a bug about this on Microsoft connect.
Firefox does not support the loop attribute. (replaying a video after it has finished)
Different browsers support different video formats, IE9 supports
H.264, Firefox supports ogg (Theora) and WebM etc, which means that you would need to provide all formats in order to be compatible with all browsers.
The rest is pretty much supported everywhere.
well, HTML 5 is not yet standardized. Due to this, every browser that support html5 works differently. As far video tag is concerned then you have to provide with different formats so as to get support on various browser list. You can test browser support on this site. Here you can get all the details about the extent your browser support to HTML5
I find this page a good resource (although it is starting to get old as it was earlier this year): http://www.longtailvideo.com/html5
On a separate note, I find if you go to mobile devices such as Android the browser support varies greatly per device. Even though they are "supported" I always get strange behavior.
As for poster, there is no good solution if you want to have support across all browsers.
In my website, it looks great on any browser but Internet Explorer. I know that older versions Internet Explorer doesn't support CSS3, so I was wondering if there were equivalents in HTML to these methods: max-width:, border-radius:, box-shadow:, and transition:.
Any help would be appreciated.
For border-radius and box-shadow there is http://css3pie.com/ but that requires Javascript in IE. For a HTML only solution you have to use images, i guess.
You are asking for a way to get some of the newer features of CSS rendered in a browser that doesn't support CSS (or let's hope you are ignoring browsers that old and instead working with a browser version that do some CSS, but not enough for your tastes). Those browsers are outdated and you are not going to get it work just by avoiding css.
If you go far enough back, you may actually end up at a point in time when there were things that were possible in html weren't in css. However, it has been quite a while now that CSS is your best shot at getting things like that to work. If it doesn't work, it usually means that the browser doesn't support it at all, not that it doesn't support it through CSS.
Of course, you can work some magic and try to fake things with javascript, but it just isn't the same.
I recommend using modernizr. It detects if a browser supports different css3 (and html5) features and, if it doesn't, you can conditionally load javascript as a fallback solution.
Internet Explorer 9 supports max-width, border-radius and box-shadow, but not transition.
Personally I don't think CSS should have transition (or animation) as styles should affect how content is displayed, not how it behaves (I am also against the behaviour IE extension for this reason).
Overall, these styles you are asking for are aesthetical, and shouldn't really be a major issue if they aren't supported by the browser your user is on.
I have read a lot about adding HTML5.js for IE7/8 support. Even though the documentation says that adding html5.js just causes IE7/8 to not ignore HTML5 tags and apply the styles.
I am really confused as to what it does, like does it have any impact on CSS3 styles working on IE OR it just causes CSS to be applied to HTML5 elements.
Could i please get to to see an easy example with/without HTML5.js on IE.
html5.js works by creating polyfills via JavaScript that specifically enforce certain rules of html5 elements in browsers that do not support them. but even after the js turns them "on", you are still going to have to target them via css to enforce styles. check out this fiddle in any browser that doesn't support html5, then uncomment out the script element and view it again. you'll see what i'm talking about http://jsfiddle.net/TR8z5/
If I recall correctly, without html5.js, older web browsers will just ignore tags it doesn't recognize, essentially showing nothing. With html5.js, older browsers will recognize html5 tags and will therefore be able to render and apply CSS.
Nope, I guess not.
CSS3 will not work on older browsers, no matter what you do.
I want to use HTML5 because it supports in Iphone also and I really liked its capabilities but what can I do if it is not fully compatible with all browsers? Specially IE family. So is there a way by adding some js script e.t.c. so that HTML5 and its js api work normally in IE also as it works on other browsers like chrome, firefox and opera e.t.c.? So that I can use it without thinking of browser compatibility issues. There are also many game engines in html5 but what if this is not supported major IE browsers. Or can some one tell that how much advantage can I take of html5 without thinking of compatibility issues?
Thanks in advance
You can use http://html5boilerplate.com/ together with http://code.google.com/p/html5shiv/ and you're good to go.
For some other cool features, like video in old IE, you need to use workarounds like Flash for video and Javascript libs for canvas.
Simply put, if the markup is valid in HTML 4, change the Doctype and it will work as HTML 5.
If you want to use the new elements like <article> or <footer>, you will need to include a small javascript snippet in order to register those new types.
document.createElement("article");
document.createElement("footer");
This will make these new elements usable and stylable like an ordinary <div> element
Polyfills let you use new HTML5 apis on older browsers. The Modernizr project keeps a list of good ones: https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills
I have designed a layout in such a way that I can make most of the images using CSS3 (using gradients, etc) I want to make as much use of HTML5 and CSS3 possible. But I can't ignore the browsers that don't support them yet. So, I was wondering is there a way to detect a browser first and then if it is a non-HTML5/CSS3 supporting browser, the code will load the images and if it is an HTML5/CSS3 supporting browser, it will use advanced code instead. This will save a lot of loading time for them.
What are your views about it? Is this a good approach? How to detect browser before anything else loads on the site?
Check out HTML5 boilerplate, it was made to address those issues very toroughly.
Also CSS3Pie can be used to add CSS3 support for IE.
I forgot wether its part of the HTML5 boilerplate or not.
