Web Development – Since the advent of the Internet, the paradigm of communication and marketing of goods and services has changed completely. Therefore, knowing what web development is essential to discover how all the pages we visit daily through and designed, along with the different mobile apps. And even more so if you want to turn your passion for online sites into a source of economic and professional development.

Indeed, a web developer’s job is one of the most demanded within the labour context due to the need that all companies have, regardless of their size, to make a place for themselves on the web and attract new potential clients.

Therefore, to understand the characteristics of web development, its functions, tools, implications, and differences with web design, we have prepared this guide, which will be the ABC when it comes to an understanding of what web development is.

Are you ready to navigate in this universe of web development? Let’s get started!

What is Web Development?

If you take your main steps with a new web development project, you will know about the possibilities offered by the Internet for new businesses. Having a well-functioning website is one of the keys to entrepreneurship. Understanding web development, also known as web development, will be useful.

It is practically an identity card to have your website, where all the information about what you do is displayed. You can allow users to interact with your product or service. Knowing what web development is, you can provide a series of actions:

  • Offer relevant information and quality content.
  • Allow users to sign up for a newsletter to obtain information.
  • Offer discounts.
  • Provide people with the possibility of making purchases of the goods or services you market.
  • Embed a direct link so they can download your web app to a cell phone.

But to offer some of these actions, it is necessary that you know what web development is and that you become a web development professional. Or also include a web developer within your work team, to whom you can transmit your company’s values so that they can express them through the website.

Continuing our discussion of what web development is, now that you know the roles of a web developer, let’s see how these roles break down into three distinct application areas: front-end development, back-end development, and full-stack development.

What is Front End Development?

If you don’t know the first steps you should take when thinking about web development and how to carry it out, let me tell you that the answer is “front-end”.

Large work teams can carry out front-end and back-end development in parallel. But in case you are just starting with web development, we recommend that you develop the front-end first.

In programming, “front-end” is everything that the user can see as soon as they enter the site :

  • typography style
  • Visual effects
  • Colors
  • Adaptation to different screens
  • movements

In this instance of our guide on web development, it is essential to highlight that the user must have a good browsing experience.

For this cause, we must bear in mind the development of web interfaces, which make the site’s content appear in a pleasant, simple and dynamic way for the user. And also, avoid changes in appearance in front of the different browsers that users use through a responsive design.

To go even deeper and learn what web development is, you should keep in mind that front-end development involves the direct aspects that affect the way users interact with the platform. We could say that the front-end developer needs to have the necessary knowledge of interface design to ensure that the user’s interactivity with the web page is efficient.

Here, all the components of a visual nature are included, such as images, videos and animations of the online site.

What are the Resources that a Front-End Web Developer Uses?

A front-end developer can use tools like HTML, CSS, or programming languages like JavaScript; or also, they usually work with frameworks.

Let’s take an earlier look at some of them:


HTML is a markup and labelling language used to make the basic structure and the content about texts, images, and videos.

Knowing what web development implies knowing what HTML tags are. An HTML tag thru of pieces of text, surrounded by less than (<) and greater than (>) signs. A word (usually in English) inserted within these signs gives the label meaning. They all have specific functions and uses.

In HTML, there are two types of tag:

  • Opening. <label>
  • Closing </tag>

When we refer to the structure of a web page, we refer to the content. For example, texts define the hierarchical order, such as h1, h2, h3 and h4, used to identify headings. Also, the attributes come into play here, which will define the tag’s behaviour. With them, you can indicate the action to carry out from the language in which the text will appear.


Moving forward with our web development discussion, we must highlight CSS’s role. Suppose HTML takes care of markup and tagging. CSS, also known as “cascading style sheets”, is responsible for styling the website.

According to Web UI at Globant and teacher in charge of our online course CSS from scratch: “Although it does not consider a programming language, it is in CSS, through which we make a website look good, it feels good and is consistent throughout the content.” In other words, CSS allows you to generate everything necessary for the web page to be pleasing to the user’s eyes: design, colours, etc.


JavaScript Web Development

Continuing with our guide on web development, you have surely heard of JavaScript, an event-oriented programming language.

JavaScript is essential to give interaction to the web page. For example, if we click on an option on a website, when programming with JavaScript, a window will open, and the information requested by the user will be displayed. Thus, multiple actions can carry out to function the web.

What is Back-End Development?

Once you know what the site will look like, let’s see what supports the web page’s structure. If you want to identify what web development is and what functions the back-end has to fulfil, we could say that everything happens behind each action that we carry out on a website. It is about the programming of a page or a website that we do not see. All the gear that works behind it and allows users to perform actions.

To exemplify and for you to know a little more about what web development is, suppose we browse Facebook and want to see a full-size photo. We double click it, and it is shown to us in the full width of the screen. Does this happen by magic? The answer is no: it happens because of back-end development.

A database needs to store the collected information for all these back-end mechanisms. So the other objective of the back-end is the design of a database and its custody to guarantee its security.

If you wonder what front-end and back-end are for web development, we could propose the iceberg example. In this, the tip, what you see of the ice structure (the front end) floats. Thanks to all the giant mass of invisible ice from the surface (the back end).

However, in short, understanding what web development implies is knowing that back-end development involves the activities necessary to get the server of the online site to function perfectly. In this way, they are actions carried out by the web developer. That is closely related to the databases and the server. These are necessary so that the website can offer a positive user experience.
