What Is a Programming Language?
Before diving into how these three programming languages work together, let's define what a programming language actually is. In simple terms, a programming language is a set of instructions used to communicate with a computer. The goal is to write code that a computer can interpret and execute.
Programming in Web Development
Let's take a deeper look at the three programming languages that make up the bulk of web development today, beginning with HTML.
HTML, or Hypertext Markup Language, is a markup language used to create the basic structure of a website. It's similar to the skeleton of a human body. HTML tags define the different parts of a webpage, from the header to the footer. These tags include <html>, <head>, <title>, <body>, and many more. These tags are enclosed in angle brackets and are used to give information to web browsers about how to display the content.
How does HTML work?
CSS, or Cascading Style Sheets, is a stylesheet language that defines how HTML elements should be displayed on a webpage. CSS allows web developers to separate the design and layout of a webpage from its content, making it easier to change the look and feel of a site without having to edit the HTML code. CSS uses a set of rules to define how various HTML elements should be displayed. These rules can include text styles, backgrounds, borders, and more.
HTML vs CSS
While HTML provides the basic structure of a webpage, CSS is responsible for creating the page's overall look and feel. HTML defines what content to present, while CSS defines how that content should be presented. Essentially, HTML handles the structure, and CSS handles the design and layout.
