Since the commercialization of the Internet in the early 90s, web development has been in constant evolution. While before the web pages were a compendium of sober text fields, nowadays the expensive presentation of multimedia contents occupies a privileged place. What was once an information platform has become a means of entertainment? In it, users prefer interactive web pages that convince through an attractive design and that can be handled intuitively. Web developers have, for this purpose, different tools that facilitate the integration of dynamic content and create web pages tailored to the users. In this sense the requirement is, however,

Technical foundations of a web page

One of the main requirements to create a web page is to have storage capacity in a server, a service offered by specialized Internet providers, that is, web hosting providers. In general, the offer includes complete packages that, in addition to the necessary disk space, also include features such as RAM, a domain of their own, databases and the relevant tools for web development. In general, the knowledge of the physical devices that take care of hosting the resources is an aspect that remains hidden for the users of the web hosting packages. In the case of alternative hosting models such as dedicated web servers, the opposite occurs, since these are rented in a data center as independent hardware components.

Domain

Any Internet project is shown with a unique and unambiguous name. The so-called domain is one of the basic components of web hosting packages. Domains strictly follow the hierarchical structure of the domain name system and consist of top-level domains (eg), free domains (second-level domains) and facultative subdomains. The registration of domains is done through an Internet provider that sends the request to the competent authority. For the choice of the domain they are available, from brief and concise formulations, up to common top-level domains.

Web space

Each web page contains data that the web server makes available to users. Therefore, web hosting packages always have a certain storage quota for HTML documents, style sheets, images, videos or databases. Data transfer is usually carried out through the File Transfer Protocol (FTP) protocol and a client program such as FileZilla or the WinSCP application. For the choice of a web hosting package it must be taken into account that the web space can be extended if necessary.

Database

If the web pages are not made available in a static way on the server, but are generated according to the needs that arise with each visit, web developers resort in most cases to relational databases. With this modality of data management, these will be structured by means of tables and a relationship with other data will be established through identifiers. The transmission and management of data structures is done, in general, through the language for SQL databases (Structured Query Language). On the other hand, MySQL, open source software, is one of the relational databases for dynamic web pages worldwide.

Web server

The web hosting packages for beginners are carried out through the so-called shared hosting. With this type of hosting, there are several hosting accounts that can share the resources of the same server. For large professional projects, web hosting providers offer different possibilities of web servers that provide customers with hardware components exclusively. Large companies are recommended, in addition to rent, the purchase of their own equipment.

Basic tools for web programming

If a web hosting package or a server are the basis of a web project, in this regard users have various possibilities to create their own website. The range of options ranges from intuitive software for web pages with limited design options through flexible content management systems (CMS) to the source code developed by oneself. While modular systems for the main pages that are guided by the WYSIWYG principle (“What You See is What You Get”) are aimed, in principle, at beginners who lack computer skills, the functioning of content management systems requires certain prior knowledge. However, web developers can enjoy a high degree of flexibility if they are the ones who program their project in an editor, which requires having basic knowledge about programming languages ​​such as HTML, CSS, JavaScript and PHP.

HTML

In the field of web development, the HTML hypertext markup language (Hypertext Markup Language) is used for the semantic structuring of digital content through so-called labels. In this way, you can define elements such as text fragments, headings, graphics or hyperlinks. A source code of such characteristics is the foundation of every web page. For its part, a static and simple web page is nothing more than a selection of interconnected HTML documents. The current version of the language, ie HTML5, expands the options for audio and video elements. On the other hand, the visual representation of the contents will be defined with the cascading style sheet language or CSS.

CSS

Cascading style sheets or CSS are understood as a language to format HTML documents in a standard way. Mostly web development company in London use CSS to assign rules to elements defined in HTML code for representation on the server. The current CSS3 specification includes instructions on design, colors and typography, as well as animations, color transitions and shadows.

JavaScript

Modern web pages interact with their users through the integration of interactive boxes, drop-down menus or slides. JavaScript comes into play in case dynamic content of this nature is integrated into HTML pages and this means taking a step beyond HTML and CSS, since it allows user interactions to be evaluated and the contents of the pages webs are reloaded, updated or modified.

PHP

While static web pages are available on the web server, dynamics are generated, upon request, through that server, which is possible thanks to programming languages ​​such as PHP. The programming PHP is interpreted by the server, and instead of the source code of dynamic web pages will be delivered directly to the server, it transmits the data to a PHP interpreter. This interpreter generates the requested web page, often based on the data deposited in the databases, and returns it to the web server, from where the interpreter’s edition will be sent to the server. Perl or Python they are other programming languages ​​used for the development of dynamic web pages.
