The Major Technologies of Web Design and Development

The Major Technologies of Web Design and Development

Computers,Website Design 5 Major Technologies of Web Design/Development Introduction There are 5 major tools that are necessary to build a dynamic website from scratch. 

Those tools are the languages HTML,CSS,Javascript,PHP, and SQL. I'm going to give a description of each of those languages and what they are used for. 1. HTML HTML is the standard language for creating web pages. The acronym HTML stands for Hyper Text Markup Language. A markup language uses tags like .... In HTML a tag represents different elements of a page. Most tags come in a set with an opening tag (i.e. ,,or ) and a closing tag (i.e. ,,or ). 

 As you can see the opening tag is made up of an open triangular bracket, followed by its name and a closing triangular bracket, while the closing tag is made up of an open triangular bracket and forward slash, followed by its name and a closing triangular bracket. 

These open and closing tags can (and usually do) contain other content (tags). There are a handful of tags that do not come in a set and don't require a closing tag because they never contain content (other tags). HTML is used to describe the structure of a page. 

Someone could make the argument that the other major tools that we will discuss aren't necessary to build a simple, static site, but there can be no website without HTML. 2. CSS CSS stands for Cascading Style Sheet. While HTML is used to describe a page, CSS is used to design it. All of the styles of a page from the position of elements to the style, color, and width of a border, to the background-color or image of elements are specified using CSS. 

CSS can be used to apply styles to groups of elements depending on type or based on an id or class that you have specified. You could technically build a page solely from HTML but it would be a very boring page, with black letters, a white background, and an unappealing layout. 3. 

Javascript (JS) Javascript is an important part of what makes a website dynamic. Javascript is a language that runs directly in the browser and therefore allows dynamic changes to be made to the website based on user input. 

Javascript can change certain elements in the page without requiring a full page reload which is faster and makes for a better user experience. Since Javascript works directly from the user's (client's) browser, it is called a client-side language. 4. PHP Just as Javascript is a client-side language because it operates directly from the user's browser, PHP is a server-side language because it runs from the server, where pages are retrieved and sent (served) to the client. PHP is a language that dynamically generates pages. 

A PHP script can be used to build an HTML page based on user input and other information. PHP can also be used to interact with databases that are on the server and retrieve information from them. 5. SQL SQL stands for structured query language. It is a general term for languages that are used to create, access, and modify databases and their tables, such as MySQL. 

To put it quite simply a database is a group of tables that store information. These tables are very useful in website design. It would be very difficult to have a login and signup system if a site couldn't store user information in a database table. This is just one of many uses for these tables.
