Markus checks the article while you write. The Check button shows the number of alerts; a click opens the list, and Go to the block leads there. The block concerned is marked in the editor, never on the site.
Alerts inform, they never block saving.
What is checked
| Alert | What to do |
|---|---|
| Image without a text alternative | Describe the image in its settings, or mark it as decorative. |
| Level 1 heading in the article | The article title is already level 1: make this one level 2. |
| Skipped heading level | A level 4 after a level 2: make it level 3. |
| Link text that says nothing | "here", "click here", "learn more" do not say where the link leads. |
| Link without text | A screen reader cannot tell where it leads. |
| Contrast too low | The chosen colour is not readable enough on the background. |
| Table without a title | Give it a title in its settings. |
| Table without headers | Say that the first row holds the headers. |
What Markus does on its own
- A link opened in a new tab is announced to screen readers.
- Colours chosen by hue stay readable, in light and dark mode.
- The toolbar and the menus work with the keyboard; blocks move with the keyboard (Alt+Shift+arrows), with no drag and drop required.
- The language of a passage can be marked (Text chapter).
What no tool sees
That the alternative text really describes the image, that headings really announce their part, that the text is clear: that stays your work. "No problem found" is not a statement of conformance.
