Cannot seem to understand why developers of a webpage don’t check first issues and standards against a w3 dot org HTML validator:
https://validator.w3.org/nu/?doc=http%3A%2F%2Fwww.reprol.com.br%2F with 26 warnings and errors, also checked here: https://seomon.com/domain/www.reprol.com.br/ e.g. https://seomon.com/domain/www.reprol.com.br/html_validator/
These one page 3rd party scans did not bring much issues: http://retire.insecurity.today/#!/scan/951fe949f458e9b593ca79631ec72c6a2ffdcbc31ec2e5316c53b9b91e92cb4b
One external stylesheet here for SRI hash issues: Stylesheets 1 issues
Tag Result
Seems OK, but consider here: http://www.domxssscanner.com/scan?url=http%3A%2F%2Fwww.reprol.com.br
