Today, many companies and individuals are experiencing the need to have their own website, which is why information on the development and promotion of Internet projects is so in demand. Many are interested in the question - how to independently create a site, the program code for which is like a foundation for a house? Let's try to understand this issue by delving into the topic of web development.
A website is not just a collection of text, links, pictures and colorful banners, it is also a program code that runs on the user's computer or on the server side. And if almost everyone can create images of the required format in the required resolution and quality today, using ready-made images from the Internet or any popular graphic editor, then creating a site program code for a non-specialist is fraught with considerable difficulties.
The quality of applications and the Internet project as a whole strongly depends on the skill of the programmer who develops the site, the program code of which may contain errors that greatly affect the speed of loading web pages and many other aspects of the entire site, including those related to security. Therefore, the detection and elimination of errors in the code is a mandatory component when creating any website. It is best to entrust the development of a complex corporate website to specialists (if you are not one), because some errors are difficult to detect, and many of them can later lead to slow loading and incorrect display of web pages in browsers of Internet users' computers. Too long loading can cause a churn of visitors from the site and a decrease in the quality of traffic,
HTML and CSS first
The basis of a web document is code written in the HTML markup language. The markup language should not be confused with the programming language, and what exactly is the difference is written in detail here . In principle, using a set of commands that offers an HTML site developer, you can set all the necessary parameters of a static web document - the location of elements (block markup), headings, paragraphs, tables, images, etc. And with the help of CSS, a special add-on for HTML, you can position all the listed markup objects, change their style - color, size, format, etc.
Then JavaScript
Interactive and animated elements, such as banners, a ticker, a feedback form, work on web pages due to the presence of scripts and code written in server or client programming languages. Scripts developed using the JavaScript programming language are very popular. Such client scripts do not use the capabilities of the server in their work and are executed on the side of the user's computer, that is, in the browser. This makes JavaScript applications simple and fast.
And finally PHP
In the case when it is required to write complex and voluminous codes, for example, for forums or guest books, programmers turn to server-side programming languages, and in particular to the PHP language , for help . PHP codes are executed on the server side, so their work may be somewhat slower, depending on the speed of the connection to the remote computer and how busy it is. Using PHP and SQL commands (a special relational database query language), you can organize the interaction of the site with databases and create interactive Internet projects - forums, online stores, bulletin boards, various directories, etc.
