Suivant le validator du W3C, on pourrait simplifier partout ! A supprimer : - Tous les slashs à la fin des balises html comme : meta, link, hr, br, img, input > Info: Trailing slash on void elements has no effect and interacts badly with unquoted attribute values. > Ref: https://github.com/validator/validator/wiki/Markup-%C2%BB-Void-elements#trailing-slashes-directly-preceded-by-unquoted-attribute-values - Tous les type="text/javascript" car `<script>` suffit Warning: The type attribute is unnecessary for JavaScript resources. - remplacer ``` <meta http-equiv="Content-Type" content="text/html; charset=#CHARSET" /> par <meta charset="#CHARSET"> ```
