The internet is a network of computers that receive and send data. Each of these computers has a unique IP address which is used to locate and distinguish them. The web, on the other hand, is a subset of the internet. The web has the web server and the web browser client. These two components make the system work. The client requests a particular kind of data, and the server provides it. API or Application Programming Interface is responsible for this communication between the client and the server.
But when the server shares the data, it is in a more raw form and needs to be arranged and formatted in a way that would be intelligible to the end-users. And this is where web development plays a crucial role.
HTML or hypertext markup language is a set of detailed instructions that are written on a manuscript meant to be typeset. Therefore it can be a language that creates instructions concerning the type, format, style, and how a web page will look. HTML structures the page into paragraphs, heading, sections, and so on.
HTML gives you the raw representation, while CSS can make your page look presentable. It gives a proper structure to a web page. CSS or Cascading Style Sheets improves how your page appears.
You can layout elements by positioning them in particular areas of your page. You just have to select the elements and specify what kind of look you are trying to achieve. CSS selectors are the rules which govern this process. You can do several things with CSS selectors. A web development course will give you a complete guide on what can be done and how to do it. For the time being, let us look at the bare minimum functions it does:
It can change the entire look of your page and make it presentable to the eyes and easy to read.
I hope you have got a basic idea about these three important elements of programming. You can now attend any web development course and be ahead of most students as you already know the ABC of programming.
HTML, CSS, and JS are together used to format, design, and program web pages. And when web pages are linked with hyperlinks and their assets like videos, images, and other elements on the server computer, it comes up as a website.
This rendering happens on the front end. The users can successfully see what is being displayed and can interact with it. In comparison, sensitive data like passwords are generated from the back end of the website. This information is not displayed on the front of the web page but exists on the server computer. Every user cannot access this kind of information simply by looking at the webpage.
This is the easiest explanation of HTML, CSS, and JS. This will help you understand the broader picture, but in order to perform well in your exams and interviews, a web development course is a must as it will broaden your horizons and teach everything about web development and design.
