Frequently Asked Questions
Which HTML elements require closing tags?
All standard container, text, and semantic elements (such as <div>, <p>, <span>, <section>, <article>, <ul>, <li>, <table>, <a>) require closing tags. Void elements like <img>, <br>, <hr>, and <input> do not require closing tags in HTML5.
How does this tool detect overlapping/crossed tags?
If you open tag A then tag B, but close tag A first (e.g. <b><i>text</b></i>), the tool flags a mismatched nesting order error and rebalances the tags to valid HTML.
