About

Detailed Description
EqualWeb Semantic Structure Analyzer is a comprehensive accessibility tool that helps developers understand and improve the semantic structure of their web pages according to WCAG 2.2 guidelines.

Why Semantic Structure Matters
Assistive technologies like screen readers rely on semantic HTML and ARIA landmarks to help users navigate and understand web content. Proper use of elements like <main>, <nav>, <header>, and <footer> creates a logical structure that makes websites accessible to everyone.

Key Features
Structure Overview Get a complete overview of all semantic elements on the page, including:

Document structure elements (main, header, footer, aside)
Navigation elements
Sectioning elements (article, section)
Form elements
Table elements
Landmark Analysis View all ARIA landmarks and HTML5 sectioning elements:

<main> / role="main"
<nav> / role="navigation"
<header> / role="banner"
<footer> / role="contentinfo"
<aside> / role="complementary"
<form> / role="form"
<section> / role="region"
Issue Detection Automatically identify common semantic structure problems:

Missing main landmark
Missing navigation landmark
Multiple main elements
Unlabeled navigation regions
Missing form labels
Improper landmark nesting
Click to Locate Click on any element in the list to scroll to and highlight it on the page.
