Kentico Xperience 13 documentation and ASP.NET Core

Most documentation about running Xperience applications under ASP.NET Core can be found in a dedicated section: Developing Xperience applications using ASP.NET Core. The rest of the documentation still applies, but some code samples and scenarios might need slight modifications for Core projects.

All major differences between the MVC 5 and Core platforms are summarized in Migrating to ASP.NET Core.

Validating HTML code

The system allows you to check the HTML validity of page code. Validation is always performed against the version of HTML declared in the validated code.

To validate a page's HTML:

Warning: During validation, your data is sent to an external 3rd party validation service. If you have sensitive, non‑public content, we recommend using other types of validation.

  1. Open the Pages application.
  2. Select the page in the content tree.
  3. Switch to the Preview mode.
  4. Open the Validate -> HTML tab.
  5. Click Validate.

If the validator finds issues in the page's HTML code, the page displays a list. You can see the following information for each issue:

  • Line - the line number of the HTML code on which the issue appears.
  • Column - the column of the HTML code (i.e. number of characters from the beginning of the respective line) where the issue appears.
  • Error message - message describing the validity issue.
  • Source - extract of the part of the code where the validity issue appears.

Note: If you navigate to another page in preview mode using links on the displayed pages, and then switch to the Validate tab, the system still validates the page selected in the content tree.
