This may be an obvious question but I really don't understand this so if someone can help me that'd be great.
Basically, I am in the middle of developing an e-commerce app for my database management class and I downloaded a free trial of the web design app Sketch. After playing around with it for a bit (having no clue beforehand what it does or how it works), I realized that the app does not convert your creations to HTML/CSS code. Rather, you can export only and image or pdf of your creation.
If I'm correct here, then what is the point of these apps? Are they seriously only for people who have no clue how to code to design a website and then hand off the design to a front-end developer to actually code your creation in HTML/CSS? And are there any apps that allow you to create a website with a GUI like this and convert it to code at the same time?
