Hi guys,

As the title says, can I master HTML, CSS and JavaScript in 4 months and create stuffs with it?

it depends, meaning the amount of time and dedication that goes into the process.

Obviously you'd start first with HTML & CSS and then JS eventually, but listen to this - after learning the basics syntax of HTML and CSS the next thing to do is Practice, yeah use the concept learned to build stuff because if helps you to aggregate and deepening the knowledge of all that is learned. You can build something like portfolio website, recruitment agency website, restaurant website, etc. you will find tonnes of mini projects on YouTube and may be by then if you decided not to go deep into CSS by using any of it frameworks you can then pick JS and add more functionality to ur frontend Application, understand this too - Practice also extensively with JavaScript like i opined earlier it helps to reinforced the knowledge.

Good luck.

yes you can learn it but doubt if you can master it within that time
