What is frontend?
Frontend is everything you SEE and CLICK on a website. The buttons, text, colors, and layout. It's the part people actually touch.
Think of a restaurant 🍽️
The frontend is the dining room: the tables, menu, and decor. The kitchen out back is the backend. You build the part guests enjoy.
It runs in the browser
Your frontend lives in the browser, like Chrome or Safari. When someone opens a page, your work shows up right on their screen.
You shape the experience
As a frontend dev, you decide how things look and feel. Is the button big and friendly? Is the text easy to read? That's your magic.
Frontend is everywhere
Apps, online shops, dashboards, your favorite social feed. They all have a frontend. Once you see it, you can't unsee it!
Look how far you came 🎉
You now know what frontend really is. Easy, right? Next up: the three tools every frontend dev uses to build anything.
