W3C validation with AngularJS directives

由 烈酒焚心 提交于 2019-12-28 13:39:12
问题 How do we go about doing W3C validation with an Angular application? Since custom directives make for invalid HTML validation, we typically see lots of W3C validation errors.

Directives can be applied to DOM elements with any of: <tag directive-name> <tag data-directive-name> (*) <tag x-directive-name> <tag directive_name> <tag x_directive_name> <tag data_directive_name> At least the

If you can grab metrics from your site and determine if the proportion of IE6 users is worth the extra
