What would you like to do?
sanitize_html_class works just fine for a single class But sometimes le wild `<span class="blue hedgehog">` appears, which is when you need this function, to validate both blue and hedgehog, Because sanitize_html_class doesn't allow spaces (because it's meant for a single class)
<?php
if ( ! function_exists( "sanitize_html_classes" ) && function_exists( "sanitize_html_class" ) ) {
/**
