The ArcGIS StoryMaps homepage consists of three main sections: Stories, Collections, and Themes. If you want to create a new story map, make sure you're on the Stories section.
If you want to use the StoryMaps Builder, you will need to access the site using one of the software's supported browsers (Chrome, Firefox, Edge, Safari) on a tablet, laptop, or desktop computer. The StoryMaps Builder requires a display width of 960 pixels so you won't be able to design a story map on your phone. Once you've published your story map, you can view it on a variety of devices, including devices with smaller screens (e.g., cell phones). For more info, see ArcGIS StoryMaps System Requirements.
An essential component of your StoryMaps project will be the cover of your story map. The cover will be where you add a title, group members' names, and a cover image or video. This is the first thing that viewers will see when they open your story map, so it's important to choose effective title and cover media to engage your audience.
Add cover image or video: You will need to upload a cover image or video from your computer. Linking to media isn't supported for this section of the story. You can change the layout of your story map's cover under the Design menu.
As you're designing your story map, you'll want to use headings and subheadings to help organize the different sections of your story. Adding headings will help improve the overall readability and accessibility of your story. After you add headings, you can use the Design menu in StoryMaps to enable a menu navigation bar for your story, which will let readers quickly jump to specific sections in your story.
You can add headings, subheadings (e.g., Heading 2, Heading 3), bulleted lists, etc. by using the customization menu in the text content block.
StoryMaps content (e.g., text, images, maps, etc.) are added as individual content blocks. You can add content blocks in the StoryMaps Builder by clicking the Add Content Block (+) icon next to "Continue Your Story..."
You can add content before, after, and in-between existing content blocks. You can also drag-and-drop most content blocks if you want to reorder the placement of items throughout your story.
