Frequently Asked Questions
Testing raw code inside a Content Management System (like WordPress) often results in plugin conflicts or theme CSS overriding your custom HTML. This viewer uses an isolated sandbox (iframe) so you see exactly what your raw code outputs without any external interference.
Yes. You can write inline CSS attributes (style="...") or use standard <style> blocks inside your HTML to format the output. The editor will syntax-highlight both HTML and CSS. For security reasons, advanced external JavaScript execution is limited within the sandbox, but standard layout and DOM elements will render perfectly.
Absolutely. AEO and GEO rely heavily on clean semantic HTML. You can use this tool to ensure your heading hierarchies (H1, H2, H3), semantic table structures, and list formats render cleanly before pushing them to production, ensuring AI bots can parse them without issue.
