The summary
The article explains why a CSS rule can look correct in the stylesheet yet fail in the browser, pointing to cascade factors such as specificity, source order, layers, and inheritance. It walks through setting up the Chrome DevTools MCP server in Codex and using its get_css_styles tool to read matched rules, inherited values, and overridden declarations from a live page. A worked example shows how an agent can identify the winning selector, and a second prompt shows how the same approach can audit a navigation component for redundant or unnecessary overrides. The author notes that findings still need to be checked in the browser before changes are made.
