Summary
Based on the provided text, it is difficult to determine the exact topic or purpose of the website as it mainly consists of CSS styling classes. However, some clues can be inferred such as references to swiping and sliding elements, media screen responsiveness, image handling (possibly for a gallery), and some specific class names like "gatsbyimagewrapper" which could potentially indicate a framework or CMS being used.
To accurately summarize what the site is about based solely on this information is not possible. Additional context or content from the website would be required for a more accurate summary.
