Responsive web at 1440px

From today through tomorrow, we decided to adjust the sizes of the components based on 1440px.

While working, the problem below came up. The slide for choosing a theme doesn't seem to fit the proportions, so I think it needs fixing, but that part is handled by another person I'm collaborating with, and I don't think it would be good for me to change the code on my own, so I think I should mention it to them.

Next, nothing looks off on My Page, but the design of the Posts / Likes category section seems really lacking. I'm trying to decide whether to build it with buttons of a similar design or with a select box.

After thinking it over, I went with just inverting the colors, Facebook-style.

Next, I took another look at the member info edit page, and it seems better than I expected.
