HTML considerations

Keep the following in mind:

  • HTML tags not listed in the table above are not supported and will be filtered out.
  • Allowed protocols for href and src are https, http, tel, and mailto.
  • Tags are automatically closed if not closed.
  • <>&s are escaped outside of legal tags if not escaped using &lt;&gt;&amp;&quot.
  • UNC links are not supported.
  • When an a tag is used, the href target URL always opens in a new browser tab.

Legacy banner

By default, ArcGIS Enterprise organizations that were upgraded to 10.9 from an earlier version feature a legacy home page configuration.


Support for the legacy home page settings will be discontinued in future upgrades. It is therefore recommended that existing organizations transition to the new home page experience as soon as possible.

The legacy home page includes a banner at the top of the page that is 960 pixels wide by 180 pixels high. You can select an image for the banner area by choosing a predefined image or uploading a file from your desktop, or you can create a custom design using rich text or HTML. Configure the banner as part of the legacy home page settings.

If you choose the Custom design option, you'll see a rich text editor where you can position graphics and text in a what-you-see-is-what-you-get (WYSIWYG) format. Delete the existing banner content and replace it with your own. For further flexibility, click the View HTML Source button in the editor, which allows you to type or paste your own HTML code.

If you select only an image for your banner, your logo appears within the banner image. If you use the custom design for your home page banner, the logo does not appear (unless you include it in your design).


If your organization is set to HTTPS only, you must access any image references in your design through HTTPS for the image or images to appear in your banner.


Below are examples of banners created with HTML. Each example includes the code that was used to create the banner. You can replace the image URLs with your own.

A home page that includes a banner created with HTML
This home page example includes a banner created with HTML.

You can use a banner larger than the banner area of 960 pixels wide by 180 pixels high, but be aware that the image may overlap certain areas of the home page, such as the name of your featured content. To help make the text visible, set the bottom of the banner to a complementary color to match the default blue or add a fade effect at the bottom.

<div id="banner-html" style="left: 0px; top: 0px; position: absolute;"><div>
<img src="" 
style="-webkit-border-radius:0 0 10px 10px; -moz-border-radius:0 0 10px 10px; -o-border-radius:0 0 10px 10px; 
border-radius:0 0 10px 10px; margin-top:0; width:960px; height:470px;"></div></div>
