Valo is a WordPress theme with super clean and minimalistic design. It is more content focused and not to much crowded to be confusing for the visitors. Modern website designs are clean designs which focus more on the main content and remove the unnecessary content from the screen. In the features of Valo it is mentioned that it is a responsive theme but It isn’t responding at all on the browser test. The layout feels like a fixed layout not a responsive one.
Valo is a completely free WordPress theme and from the live demo it looks like it can be used for any business website, agency website, blog website or corporate website. But it depends on the extensiveness of theme options. If it doesn’t have theme options to support that customization, it will be very hard to make it in to your desired website. Valo has a full list blog but with clean layout which makes it look very beautiful and attractive. Blog has a sidebar and sidebar shows many widgets e.g. recent comments, recent posts, archive and categories.
