Does HTML5 eliminate other programming language?
Simply put; HTML and CSS are presentation markup languages, dealing entirely with the way things appear rather than how things work. Javascript (for the most part) also deals with the presentation rather than functionality. C#, Objective C and Java have more to do with the functionality of the application being developed; database interaction, processing of orders, mathematics...etc.
Which programming language do you use for creating a website?
Dear quoran, I suggest you to understand the architecture of website before creating one. Most websites have three tier architecture like below. So, you need to know multiple programming languages for implementing different tiers. Presentation Tier: This occupies the top level and displays information related to services available on a website. It supports the Graphical User Interface (GUI) which displays data to the user and accepts input from the user. For creating GUI use languages like HTML, CSS, JavaScript.Business Tier:The functional module that actually process data. This tier runs on a server and is often called the application server. It controls application functionality by performing detailed processing. For implementing business logic languages like Java, C# can be used.Database Tier: A database management system (DBMS) stores the data required by the middle tier. This tier runs on a second server called database server.SQL queries are used to interact with databases.
What is the difference between logical and physical tags in html?
In my many years of working with HTML, I've never noticed tags being distinguished between logical and physical. However on searching I have found that there many pages on the web that do use this distinction. I think the more normal distinction is between semantic and presentational tags, which are pretty much the same as logical and physical tags respectively. In HTML 4 most of the presentational tags, such as font, have been deprecated, and are not valid in HTML 4 Strict. Semantic tags (logical tags) convey meaning. Semantic tags include h1 which says that the content of the tag is a Level 1 (most important) heading, or blockquote which says that the content of the tag is a (relatively large) quotation, or strong which indicates that the content should be strongly emphasised. Presentational tags (physical tags) suggest how content is to be displayed, not what it is. Presentational tags include the afore mentioned font which can be used to change font size, font family, colour. The b tag is another presentational tag. It indicates that the content should be displayed as bold. Best practice has been since about the turn of the century, to only use semantic tags, and use CSS for all presentation. This has two benefits - its much easier to maintain and results in smaller files.
