I would like to implement/embed a notes area where people can write some notes on my website.
is this possible with some simple html script? And if yes, does someone know where to find?
Here you can see what I mean: http://bwmbroadcast.org/player/flash?stream=MP4BW489-3A.mp4
Any help would be appreciated.
Thanks
If i were you i would implement a HTML-5 local storage system, http://net.tutsplus.com/tutorials/html-css-techniques/building-persistant-sticky-notes-with-local-storage/
You cannot do this by simply using HTML+CSS.
You have several options:
Use a simple HTML form that submits data to the server and save the notes to a database (you can use PHP and MySQL for this). Form submission can happen through AJAX. This seems to be the right way to me.
Use Javascript and save the notes in a cookie (this way you do not tie it to a user but a browser, I don't recommend this)
Use benhowdle89's solution, you need Javascript for that too, and HTML5 local storage support is not in every browser right now (still, notes will be tied to the browser, so if I visit your site from a different computer/browser, I won't be able to access them).
UPDATE: If you don't want to store notes at all, and only want it for printing, you could check out contenteditable. No need for Javascript here. See: http://html5demos.com/contenteditable

I'm learning basic web dev and started with HTML, CSS, Bootstrap. Haven't touched PHP or anything server side yet.
What I've done so far is I've created a pretty basic registration form with 5 fields and what I'm trying to do is display the input of those fields in a table that I've created on another page. The submit button has the "method" and action. Now, I've Googled a ton to find some solutions and have gone through most of the questions of this site but I still can't find out to achieve what I'm trying to do without the use of PHP/JS.
So, is it even possible to read form data from another page like this without the use of JS/PHP? If so, how do I proceed and what needs to be done? I can post the source code but I don't think it's going to help since there isn't much there, everything else is working fine except for finding a solution to this.
Thank you.
You need a programming language.
If you want to do it entirely client-side, then that has to be JS.
If you want to do it server-side (which allows you to access the data and, optionally, make it available to other people, instead of limiting it to the user of the browser) then you can use any programming language at all (although JS and PHP are among the most common choices).
Since you are trying to create a registration page, you'll need to use server-side programming.
You necessarily need to use JavaScript / PHP.
Since you are just starting, I would highly recommend you to check out the W3Schools tutorials on HTML, CSS, JavaScript, PHP, Bootstrap and jQuery.

So this is long gone but I was actually able to resolve my problem without using anything other than basic HTML , so here's how I did it for anyone else who's trying to find the answer to problem (probably not, you don't usually do this professionally and basically this was a challenge from a friend).
So, two things.
SessionStorage
LocalStorage
This is built-in to your browser and you can use it to achieve simple tasks by simply assigning values to it. They'll remain there and you can use however you want.
But, as the name implies, sessionstorage will only retain those values during the session (the time you have your browser open for) while localstorage can retain it indefinitely. Not sure if I can link other sites over here so just Google these terms to learn more and how to use them.
I am working on a prototype for a project that is somewhat similar to the facebook's "like" button. Basically it's an embeddable piece of code that can integrated with any website.
I am looking for a way to fake this integration for a demo. Basically I want to show a familiar web page (like http://www.cnn.com) with my code already embedded. Since I obviously can't do the actual integration right now, I need some way of faking it.
The only thing I can think about is to use http://www.httrack.com/ to download the page I want, and then change it locally. The problem with this is that it is clear that the page is hosted locally and not on www.cnn.com.
Is there a better technique for doing this?
If you use Firefox browser, you can use Greasemoneky and with JavaScripts, embedd your content inside that page. You can eaven add events, that will open some popup windows, etc. to show action of such a script.
That is easy approach, there are ton's of examples in their forum, and good documentation, how to use it.
You can write your own userscript (i.e. greasemonkey) to modify the page on the fly.
Even though I think it's a bad idea to do this (not sure if stackoverflow allows to ask such questions), but what you can do is edit the hosts file (if you're on windows) and add a line
127.0.0.1 www.cnn.com
it means that when you visit the website cnn it will display the domain name in the browser but it will use your localhost server to display the content.
Is there reliable a way to detect such browser capability from the user agent string?
HTML5 isn't a server-side language.
Anyway, there isn't a way to reliably detect UA capabilities, for instance they could have Javascript turned off, addons installed, etc. etc.
You could use some SS methods such as PHP's Browser Detect, but aside from that there's nothing more you can really do. This is not at all comprehensive at all, though!
Everything such as this should really be done client side in Javascript, as you can easily detect what's available and what isn't. There's a number of libraries out there that will do this, but it's very simple to do yourself if you know what you want so using one shouldn't really be required. Furthermore, you should never want to do this based on User Agent strings, as I mentioned before there's addons available that can modify behaviour etc. You should literally just check for the feature you wish to use rather than restricting yourself to a certain version of the browser.
Not reliably — you’re stuck with figuring out the browser version from the user-agent string, and maintaining a list of which browser versions support the API.
You could, however, detect it on the client side using JavaScript:
Modernizr
Mark Pilgrim’s suggested History API detection code
and then do a redirect via JavaScript (i.e. by setting window.location) to let the server know whether the API is available or not. That would be the usual way to redirect to a URL starting with # (as per your comment on rudi_visser’s answer.
This is not server side (so it probably does not answer your question, I thought it would be helpful though):
Have you looked at Modernizr
It is a javascript file you include in your HTML page. You can then use its properties to detect if a particular HTML 5 tag is supported by the browser.
I imagine there must be out there a website that collects information about HTML 5 feature and what browsers version started to support them.
This might be a good way to decide based on your website profile, if you can apply that HTML 5 feature without a fallback for your visitors.
Do you know such a site/resource ?
For example I want to know what browsers support the multiple upload feature for inputs and what browser version was the first.
Update
I'm not pleased with the sites suggested so I'm opening a bounty.
Suggestions so far: Html5Test, Caniuse, modernizr.com, QuirksMode
Update 2
Some people don't understand the question. I need to implement the multiple upload feature. I know from analytics what browser are they using ( I know this is not 100% correct ).
I'm willing to sacrifice some of the visitors by not offering some advance features but I need to understand how big is this procent. I'm NOT trying to DETECT in anyway the browser. It's a similar approach with other sites that dropped IE 6 support.
So please don't talk about bad practice.
Try to look at Html5Test or caniuse.
If it's server side, you can analyze user agent to find out if client's version supports HTML5. Wikipedia is your friend.
If it's client side, there's Modernizr library.
A quick search gave me this interesting result (reproduced in several blogs): http://www.findmebyip.com/litmus/
And you can may also want to take a look at this list of how to detect each feature: http://diveintohtml5.ep.io/everything.html
Here is another website, quite incomplete but verbose and "work in progress" as of March 2011, so it might be worth keeping an eye on: http://html5accessibility.com/
This one is off topic, but since I found it, I add it. CSS compatibility in IE browsers (very extensive): http://msdn.microsoft.com/en-us/library/cc351024(VS.85).aspx
And here you can find info specific to the gecko engine: https://developer.mozilla.org/en/HTML/HTML5
And, of course, MDC has compatibility tables for each feature, but separated in different pages, not as a table, e.g.: https://developer.mozilla.org/en/HTML/Element/input
http://www.modernizr.com/
HTML5Test.com collects the information but they don't give detailed reports for perusal.
A good reference site for some stuff is http://www.browserscope.org/ but that doesn't go into a lot of detail with HTML5 specific support
Another source of related stuff is http://w3c-test.org/html/tests/reporting/report.htm which is creating a set of HTML testing tools that can be run.
You or someone who wanted to create this information could use these tests and then store the UA String of each browser that hit the site with the results of each test.
Then you could just find the earliest version of each browser type that a feature successfully run on.
I think this information is stored in the databases of the sites mentioned but they just don't display it which sort of sucks. Maybe try emailing them and suggesting they add these reports.
Take a look at caniuse.com, it’s exactly what you are searching for.
QuirksMode is also a great resource, and there is an entry for multiple files input.
My vote is for:
http://www.findmebyip.com/litmus
Which i found via this blog:

You should try this website. I hope this is what you were looking for.
I am thinking to create an website that generates HTML through a wizard.Finally, I want to make the users to buy the generated HTML source if they like what they see.
But I don't want to let the users to steal the HTML, CSS and JS that I use to create the effect they want.
I want a technique which is immune to Firebug and Right Click -> View Page Source.
Any thoughts ?
edit: I remember something about iframes or frameset, but I'm not sure how to fool the browser and Firebug to execute the code without updating their capability of showing that source code. A popup is also a possible solution.
edit 2: html hosted in silverlight ? will you use it ?
The best thing you can do is to just obfuscate your code. Trying to hide the source is not going to work (for ex: if you disable right click-> view source that doesn't stop them from using the menu or saving the page or using a shortcut key or writing an app to stream the http request into a file and open that, etc).
Firstly, depending on what you are doing you can have the HTML code loaded through JS after the page load (AJAX).
As far as your JS goes:
Free Obfuscator
Not Free Obfuscator
In the end though, there is no stopping someone who really wants to get that source. Even obfuscated code can be rebuilt (though it's hell on wheels painful depending on how good the obfuscator is).
To really protect the sample HTML from prying eyes, you'd need to render it on the server-side and only pass image data to the client. If you want the user to be able to interact with the sample as if it were a normal Web page, you'll also need to send their pointer and keyboard inputs to the server and update the displayed image when necessary. At that point, though, you're basically making an HTTP-based version of VNC. This is definitely possible, but I don't think it will be easy, and I doubt there are any existing software packages to let you do this. If I were you, I'd rethink my business model a bit.
Sending XSL-templated XML to the browser may be enough fool some, and it will work more or less the same in many modern browsers including IE6 (maybe even 5.5).
But really, trying to hide the HTML code isn't going to work if anyone halfway serious wants to get it.
I am thinking to create an website that generates HTML through a wizard.
Finally, I want to make the users to buy the generated HTML source if they like what they see.
If this is what you need you might consider the possibility of creating a preview of the page as an image, and provide the download of the source only after the user agreed and paid. There is no magic way to let a browser display a code that you can't see.
You can make a video, showing the functionality and upload the same, which may help users to view / feel it.
