The nice thing about horizontal scrolling is that it gives a dynamic impression. The larger the screen, the more pronounced the feature is, since it makes lavish use of the monitor area.

Horizontal scrolling can be inconvenient in terms of convenience. Longer texts are harder to write and read, because the Web is predicated on vertical scrolling.

However, “HORIZON” has cleared the various issues of horizontal scrolling. It incorporates only the best aspects of horizontal scrolling.

For example, the top page and some sub pages use horizontal scrolling, but　blog and news pages are scroll vertically.

Pages can be created both vertically and horizontally, So you can use only the best aspects of horizontal scrolling without sacrificing convenience.

It would be cool to make the ABOUT page scroll horizontally too.
