I finally published new design of my portal web site. kentaimamura.com
I tried to use Dreamweaver to be able to write code.
And at the same time, I learned a platform of responsive design, Bootstrap, so I don’t need to make many layouts for PC, tables and smartphones.
But eventually I gave up to do that.
The site only has the top page. I realized that making 3 layouts is much easier than adapting responsive design.
