No “pinch and zoom” required! Last but certainly not least, we will get a thorough introduction to the most ubiquitous, popular, and incredibly powerful language of the web: Javascript.
You’ll be able to code up a web page that will be just as useful on a mobile phone as on a desktop computer.
We will then advance to learning how to code our pages such that its components rearrange and resize themselves automatically based on the size of the user’s screen. We will start from the ground up by learning how to implement modern web pages with HTML and CSS. In this course, we will learn the basic tools that every web page coder needs to know. You send an HTTP request to that site and get a response that is not a website, but only “JSON formatted” text.Do you realize that the only functionality of a web application that the user directly interacts with is through the web page? Implement it poorly and, to the user, the server-side becomes irrelevant! Today’s user expects a lot out of the web page: it has to load fast, expose the desired service, and be comfortable to view on all devices: from a desktop computers to tablets and mobile phones. For that, you can access a weather API ( application programming interface) from a service which offers API access, such as DarkSky. Let’s say you write a website that displays today’s weather. It is a format, used to exchange information on the Internet. So without wasting more time let’s start the list. HTML stands for Hypertext Markup Language. So you should always remember no matter which learning medium you are choosing to learn HTML and CSS, whether it is an online course, blogs, or books you should always invest your time and energy in practicing the concepts. I hope it helps you understand what these languages are, and what they do.
In this article, I want to explain the difference between HTML, CSS, and JavaScript with an analogy. This is not a programming language, but it’s something important you need to know. The difference between HTML, CSS, and JavaScript 23rd Oct 2019.
You could change CSS classes while the website is running from JavaScript. You can also change styling from JavaScript with the help of CSS. In HTML you can define elements that have classes or IDs, which you can manipulate with CSS or JavaScript. You need to know all three languages because they work together. It makes more sense to know the basics first. But it’s not recommended that you start off by learning a framework. They are libraries that help you build applications faster and easier. You have probably heard of JavaScript frameworks such as Vue, React, Angular which are in very high demand right now. To make it even more complicated: You can also use JavaScript to write server-side code (or code running locally on your computer), not only in the browser. There are millions of JavaScript libraries that other people made that you can use in your own project.įor example in this blog, there is a library called Prism that analyzes the code snippets I write in my posts and adds syntax highlighting (making it easier to read for developers) to it. The order you need to load your external scripts may depend on their content. There are a handful of exceptions, but most of the time your CSS will be in an external. That’s why it is so vastly popular in recent years. Your tags should (must) go in the head of your page. Learning JavaScript will take up most of your web development time because it has many things to know and virtually unlimited possibilities of stuff you can do with it. Here’s an example of a simple HTML site: Here the developer defines what elements should the website have: Buttons, Images, Text, Links, etc. HTML (short for Hypertext Markup Language) is the skeleton of a website and is the very first thing being loaded in the web browser. I won’t go into detail about how to write code for each language, because the in this post is only to understand why web developers need to know that many languages in order to program a website. This guide covers all the primary languages for web development so no matter what you choose to learn. There is no right or wrong answer because it all depends on what you want to do. Backend devs could learn basic HTML/CSS but really focus their efforts on a backend language+database engine. I’ll try to answer it as clearly as possible and explain what each of the languages does. Frontend devs can learn HTML+CSS and some JavaScript. Why do I need to learn three languages – HTML, CSS, JavaScript– to build a web application?Įach language plays its own part and is there for its own specific use-case. In this post, I explain what HTML, CSS, and JavaScript is and why do you need all three of them to create a web application.Īs I scrolled through some web development forums, I noticed that more people than one have the following question (or a variation of it):
