Welcome to the front end.
In a website you need to find your information immediateley. Clear and concise.
Also a well-defined sense for shape, colour and balance is an indispensable item in a frontender's toolbox.
Of course, technology and design are not the only parts in the mix. "Usability" is term for something we take for granted: suppose we rent a car, then we expect the accelerator and the brake to be in their usual place. That comes in very handy and everyone can drive off without a problem. Why is this not the case with many websites? A good frontend developer will find the easiest way for a visitor to use a website or webshop. This brings understanding, a definite feel-good factor and, should that be the goal, more revenue.
And that is not rocket science.
