Offline HTML Verification Tool

Input HTML (full doc OR snippet)

Paste a snippet (example: just a table) and FIX will output only the snippet (no doctype/html/head/body).

Fix removes only comments that contain “ERROR #…”. Your other comments remain.

What this checks / fixes

Full document only: Fix normalizes the top shell (XHTML 1.0 Transitional doctype, html attrs, required meta tags).
Rule 1: Every <table> must have role="presentation".
Rule 2: Images wider than 50px must not have an empty alt (Fix will NOT auto-fill alt; it will warn).
Rule 3: Direct text inside <td> is wrapped in <p style="padding:0; margin:0">.
Rule 6: If a table has a pixel width, any row with multiple column widths must sum to the table width.
Rule 7: No empty <p></p> tags.
Fix adds table styles border-collapse:collapse; mso-table-lspace:0pt; mso-table-rspace:0pt; and adds border-collapse:collapse to every <td>.
Fix adds image styles display:block; border:0; to every <img>.
Fix removes all <tbody> tags from the output.
