My question is related to popular HTML. Is there any suitable alternative of HTML code which works more effectively and efficiencly for the website pages and also easy to handle.
Not sure in what context you mean "effectively and efficiency". You may code your website in PHP /ASP/ etc using database etc to reduce effort to update, easy to maintain however in a browser the final generated output will be HTML.
No matter your chosen programming language, to front face the internet with any modern browser at least a few lines of HTML are needed regardless if it's video IN A web page, and image IN A web page, flash IN A web page... It all needs HTML so your question is there an alternative to to HTML itself, the answer is no.
Yeah, if you are looking for a replacement, I would suggest purchasing a script that does everything for your particular niche.. or look into site's that turn website making into a GUI.. but there is no standard replacement in terms of coding language that I am aware of.
HTML is a markup language, same is the advanced XHTML. All others are programming or scripting languages. Till date there is no other markup language. Whatever be the programming language or scripting language is, HTML is the only thing that a browser understands. So HTML or XHTML has no alternative. All other languages are used to to generate the HTML.
That's a very nice feature in html5. The less JavaScript the better. I've been having a lot of fun with canvas and was even able to get simple real time interaction with it and a php websocket. The quake II demo that was released by google also is a huge indication that we will be seeing a lot more of these incredible improvements in development times and performance.
Html is For Markup .......... There Cannot Be an Alternative For This But We can Improve The Site Quality By Adding jAvaScript , Jquery , And More .... PHP & Asp.net Are Programming Languages ........
Plain text? What are you using the website for? Scripting languages such as ASP.net, PHP, Python, ColdFusion etc. are languages for producing HTML - they are not alternatives to it.
