Put simply, web development revolves around the building and maintenance of websites, and it encompasses a wide range of technologies and tools.
When a web designer is given a project to build a website with specific requirements, a specific theme, font, colors, header, or creative aspects like animations, it is their job to take that big idea and break it down into small pieces. These pieces are then translated into programming instructions that the computer is able to understand, including the correct order of instructions and the right syntax.
Every single web page you have ever visited was built using a sequence of instructions, one on top of the other. Without a web browser, that code is merely just a text file. It’s only when that text file is opened with a web browser that the magic happens. The browser fetches the HTML and other coding languages and then translates the code into a coherent, structured webpage that can be interacted with.
Regardless of the complexity or number of technologies involved, HTML is at the core of every webpage. It is an absolutely essential skill for any web developer to have in their toolbox, and it is the perfect starting point for anyone who wants to create web content.
So, how does HTML work? HTML stands for HyperText Markup Language. The term ‘markup language’ means that instead of using a language that directly performs a function, HTML instead uses various tags that can identify types of content and the purposes that they serve in order to display each webpage. HTML tags, also known as ‘elements,’ have intuitive names such as header tags, paragraph tags, image tags, etc.
Take, for example, the blog you are reading right now. If we were coding this page from scratch, we would use the HTML tag <p>. The brackets denote the tag, and the letter ‘p’ inside the brackets tells the computer that we want to create a paragraph instead of some other type of content. Once we have used the <p> tag, the computer assumes everything that follows is part of the paragraph until you close the tag with </p>. So, our page would look something like this:
<p> This is our blog. </p>
By using HTML tags, you can add headings, format your paragraphs, make lists, emphasize text, create links, insert images, control line breaks, build tables, and much more.
CSS stands for cascading style sheets, and its primary responsibility is dictating how each HTML element of a website should actually appear on the user’s web browser. While HTML focuses on providing the raw tools needed to structure content on a given website, CSS helps to style that content so it will display in the way the creator meant it to be seen. CSS and HTML are kept separate to ensure that the webpage is built correctly before they are reformatted.
While HTML acts as the basic structure of your webpage, CSS is what gives your page style. Those stylish fonts, eye-catching colors, and sleek animations are all thanks to CSS. It is an incredibly powerful and important tool because more than just making your webpage look great, it also sets the tone and mood of your site as a whole. On top of that, CSS is also what allows websites to adapt to different browsers, devices, and screen sizes.
