Placeholders that must not appear
• image, van Gogh, SWR3, Notes, 7juli, myartpics.

Do not / must
• No animated images longer than 5 seconds that cannot be paused or stopped. 
• Avoid absolutely positioned content when the visual order does not match the DOM reading order. 
• Do not auto-refresh pages (no meta refresh) because it confuses users. 
• A document title must be present (must not be blank). 
• Headings must not be empty. 
• HTML form controls must have an accessible name (label/aria-label/aria-labelledby). 
• iframes/frames must have a meaningful title attribute. 
• Do not indicate links by color alone; add a non-color cue (e.g., underline). 
• Use descriptive link text (avoid “Click here,” “More,” “Read more” without context). 
• Do not nest interactive elements (e.g., no a inside buttons). 
• The visible label must appear in the accessible name of links/controls. 
• Avoid look-alike Unicode characters in English words; add lang if text is another language. 
• Do not use nested tables unless they are truly data tables and correctly marked up; otherwise mark layout tables with role="presentation". 
• Each page must declare a language via the lang attribute. 
• Ensure sufficient text/background color contrast per WCAG. 
• Do not disable zoom in the viewport meta tag (no user-scalable=no, maximum-scale2X). 
• Do not use the blinking element (obsolete; users cannot turn it off). 

Search / structure checklist
• Provide exactly one hh1 heading on a page.
• Title and meta description should be different.
• Have exactly one meta description.
• No invisible text.

Standards / markup notes
• Some elements do not allow certain attributes; only use attributes that the element supports (e.g., avoid invalid alt, color, height, name, URL, width on elements that don’t support them).
• Do not place “Doctolib” comments (not permitted here).
• “Imad” must appear first in the CSS (project-specific rule).
• Fix errors in document-type elements; IDs and other identifiers must be unique.
• No blinking text.

Compatibility
• Prefer modern formats (e.g., WebP images).
• CSS units like vmax are supported; test across browsers.
• Use RGBA for colors when transparency is needed.
• The old Netscape “blink” extension is obsolete and must not be used. 
• Some color/underline styles are not uniformly supported—verify cross-browser.

Language & CSS
• Text/background contrast must be adequate (see contrast note above). 
• Provide language attributes. 
• Include a table of contents where appropriate.
• Prefer relative CSS values (for better scalability and accessibility).
• Avoid inline !important that blocks user overrides (line-height/word-spacing). 

Usability
• Do not underline non-link text (users expect underlined text to be a link).
• Provide skip links (jump marks).
• Include a search option.
• Use a clear, legible typeface.
• Minimum font size: 12 pt (or equivalent accessible sizing in CSS).
