I am adding HTML snippets and they are not being triggered. I have created some Perl ones and they work fine. The HTML ones are not firing. I created an HTML5 header one and it did not work. So I created the default one (as shown below). The files is in “…Snippets\HTML\test.sublime-snippet”.
<snippet>
<content><![CDATA[
Hello, ${1:this} is a ${2:snippet}.
]]></content>
<!-- Optional: Set a tabTrigger to define how to trigger the snippet -->
<tabTrigger>hello</tabTrigger>
<!-- Optional: Set a scope to limit where the snippet will trigger -->
<scope>source.html</scope>
</snippet>
