Art is a diverse range of human activities in creating visual, auditory or performing artifacts (artworks), expressing the author's imaginative or technical skill, intended to be appreciated for their beauty or emotional power.
A similar activity happens when the elements of art are combined. Instead of elements such as hydrogen, oxygen, carbon, in art you have these building blocks: line. shape. form. space. texture. value.
