Code Inspections in HTML

In HTML, ReSharper 2025.1 provides two kinds of code inspections: 2 inspections that detect errors such as broken syntax, unresolved symbols, compiler errors, and so on (you cannot configure or disable any of these inspections), and 41 proprietary code inspections, any of which you can disable or change its severity level.
These code inspections help you detect code issues in design time in all open files, and additionally they allow you to find code issues in specific scope.

Configurable HTML inspections are listed below, grouped by their categories.
