If you want to upload different content over three columns -- such as services, magazines, types of donations, etc. you can use the three column content type.
For each column you are asked to upload an image (either as a circle or as a rectangle), create a heading and provide content and then a button for a Call to Action which can direct a person to a specific page, story, to an external link or to download a document. You are asked to provide alternate text for a reader that is vision impaired and may be using a screen reader (which will describe what the image is).
Here are some examples of three column content:
