Is it necessary for a layout designer to be able to work with a layout?

Question

Layout

The question is:
Is it necessary to completely create a site in Photoshop first, and then type it up? Or can you just look at the source and make it up?

Answer 1

I personally open the Chrome Developer Console and layout the site through it, live. But this is about small or personal sites.
And for prof. work, of course, you must be able to work with layouts in Photoshop.

Answer 2

I would say it depends on the complexity of the layout. In addition, usually the layout is given to you by the customer "as he sees it." If you immediately make up, then the client may not like it.

Answer 3

The layout is needed, because. after agreeing with the customer, it is easier to make changes to it than to the finished layout
