With Inflearn, your first encounter with web development! 🛩️
“I really need to have a technical skill...” Have you ever had this thought?
• How was the work you performed today?
• Are you doing work that requires special skills and cannot be easily replaced?
• Have you ever had the ominous thought that robots or AI might take away your job someday?
The world is always changing rapidly. Just as fast as that change, the "work" we do is also evolving quickly.
Fast food restaurants filled with kiosks, Americanos made by robots,
and a job market full of developer recruitment that has made this new daily life possible.
Just as the world changes at lightning speed every day, we must also continue to increase our own value and evolve.
Inflearn would like to suggest your very first step toward that challenge of change.
How about starting with the easiest things, without any pressure of failure?
Let's think back to our childhood for a moment. What was the very first thing you learned in life? It was how to speak—in other words, 'language.' The same applies to computers. To make a computer work exactly the way you want, you must learn the language used to communicate with it.
So, which of the many computer languages in the world should you learn? For those encountering IT technology for the first time, I recommend starting with the languages required for web development. This is because the web, which we encounter and use every day, will continue to be an important technology in the future.
In particular, HTML, CSS, and Javascript are languages you must know
if you are starting web development.
• You can define the content and structure of the web with HTML,
• create stunning designs with CSS,
• and define how the web functions with Javascript.
To create the websites you see, you must understand and be able to use the purposes and syntax of these languages.
Even the screen you are looking at right now is made of these three languages!
Inflearn Original: Introduction to Web Development is designed for beginners taking their first step into web development, covering the essential content necessary for the field. After going through the process of understanding where each syntax and concept is used through hands-on practice, you will conclude by creating a web page similar to an Instagram card, allowing you to see firsthand what you can achieve through web development.

I believe that opportunities for learning should be free from economic and physical limitations.
We pursue equality in opportunities for growth.

I am writing a review of the course with only the lectures left to verify through practice. Pros: The lectures are good. The explanations are easy to understand, so the content of the course is easy to understand. Cons: The materials are insufficient compared to the price of the course, and the lecture volume keeps changing from the middle part. This course consists of 56 lectures in 704 minutes and costs 38,500 won. The lectures are good, but the materials are insufficient. The lecture materials, PPT, are also very poor, and there are almost no examples in the PPT, and only a few are shown in class. Despite the course costing close to 40,000 won, I think there are too few materials. Also, the volume is constant in the beginning, but from the middle part of the course, there are lectures with low volume and lectures with high volume. It is not a small price, but I think that part is a bit too much. Assuming that you do not have a book and only listen to the lectures, I would not recommend it because there is not enough materials compared to the price. However, if you have a book about it and you say that it doesn't matter as long as the lectures are good, it would be okay. I give this course 3 stars because it is included in the first element and the lecture sound is not consistent compared to the price.

Before I go in, I am a pure liberal arts major and have absolutely no knowledge of programming. I am currently a brand manager at a foreign company in charge of a brand, but I listened to it because I needed to know about digital. I think it is a really good lecture just because I didn't think I should give up. When I listened to HTML and moved on to CSS, I listened to it over and over again to understand, and I thought, "Oh, if I do this, I can apply it a little bit." It seems to be the best as a concept lecture. I will continue to use it. Thank you, Inflearn.
