What is a Front-End Developer?
Front-End developer is a person who writes the code for the appearance of the site, there is also a Back-End developer who writes the code for the functional part of the site. If you cross these two professions you get a Full-Stack developer
1. The basics you need to know
Many languages can be used to write Front-End code, but first, I advise you to start with the "language" of HTML. With the help of it you will be able to create, of course, not websites, but standard Internet pages with text, pictures, etc., but HTML-I certainly won't be enough for you to consider yourself a Front-End developer. There are many ways to learn HTML, we will analyze them a little later.
Next, I will advise you to learn the basics of the CSS language. You will need it to make a good website design, standard animations, page design. There are also many ways to learn CSS, we will discuss them a little later.
In order to write a good design for a website, you may not always have enough CSS, so you need the basics of JavaScript. But if you fully learn JavaScript and Node.js, you can even write Back-End and become a Full-Stack developer
2. Time
It won't take you a lot of time to learn these programming languages, but that doesn't mean it's that easy. You should always learn not only from theory, but also from practice. It takes a lot of practice to fully navigate the programming language, otherwise you will be very confused if you take up freelance work ahead of time. Try to write a couple of pages for yourself to understand and understand languages well
3. Mathematics
We will not focus on this for a long time, if you know mathematics well, excellent, if not very much it does not matter. There is enough mathematics course up to grade 9
