For what do I need to pay attention if I want to my Website to work for all Browsers? I included the following files into my .html, but the firefox does not show my navigation right and in Explorer my overlay which is a section is not right too.
<!-- HTML5 shiv and Respond.js support IE8 or Older for HTML5 elements
and media queries -->
<!--[if lt IE 9]>
<script src="https://oss.maxcdn.com/libs/html5shiv/3.7.0/html5shiv.js">
<script src="https://oss.maxcdn.com/html5shiv/3.7.3/html5shiv.min.js">
</script>
<script src="bower_components/html5shiv/dist/html5shiv.js"></script>
<script src="bower_components/html5shiv/dist/html5shiv-printshiv.js">
<![endif]-->
I found out my explorer is the version 11 but I dont find any help for that.
What can I do to include my website for Mozilla firefox and explorer is the main question.
check out this post. I think this is the same problem, if it isn't just leave me a comment.
