I am learning Phoenix now and see a lot of Heex, use of Tailwind, and other things that are not just pure html and css.

How do you all tend to design your layouts? Do you use any any third party tool (for example Figma)? I’m guessing nobody here uses something like dreamweaver to lay out any html file and then translate it to code yourself, so I am wondering how you go about it, what is your process.

Do you just lay it out semantically with containers, flex grids, etc? What do you do when you want to move something, do you just change it in the code or do you use any visual tool to visualize the changes as you’re making them? Please describe your overall approach.
