Parallax shown below.
A Parallax can make a subtly change to the background. The image focus may move. This effect can be used on page backgrounds and single items, as shown below.
All things in moderation. Animation adds visual interest. Keeping movement to under 5 seconds will be appreciated by those using screen readers.
Page Layout Trends
Page collection sites can scroll as one continuous page or collection of pages. One-Page sites use a single non-scrollable page that gets new content as needed. The best practice may be in the middle.
Card-based design enables content to fit in all screen types and sizes. There might be a brief amount of text, such as a product description. Cards are miniature, condensed web pages.
