best-practices

A web app security audit should enforce HTTPS, Content Security Policy (CSP), Subresource Integrity (SRI), and secure headers. Applying these modern web development best practices ensures safe data handling and protects against vulnerabilities during security hardening.

To implement CSP and SRI correctly, apply structured web security best practices that enforce secure headers and safe data handling. These standards prevent cross-site scripting and unauthorized resource modification during security audits and code reviews.

Browser compatibility and accessible markup best practices require proper doctype and viewport configuration, alongside polyfills guidance. Following these performance and compatibility standards ensures web applications render consistently across different environments.

Yes, you can use these best practices for project modernization and code quality reviews. They provide audit checklists and maintenance guidance to systematically upgrade security, compatibility, and code quality across existing web applications.

You need polyfills for web application compatibility when supporting browsers that lack native modern features. Following compatibility best practices alongside proper doctype and viewport settings ensures consistent rendering and accessible markup across diverse environments.
