Google app script : Separating HTML and CSS

Question

i have a question connected with title. Currently i am trying to follow google "best practice". https://developers.google.com/apps-script/guides/html/best-practices I have no idea why its not working. Here is a MainPageCSS.html

<pre>
<style>
p {
  color: green;
}
</style>
</pre>

Then comes server-side function:

function includeCSS() { 
var content = HtmlService.createTemplateFromFile('MainPageCSS').getRawContent();
  //.getContent();
return content;
}

I am using a sidebar via HtmlService, and calling google.script.run.withSuccessHandler(SuccessAddCss).includeCSS(); I tried different ways of adding css into page, but noone worked...

function SuccessAddCss(Style){
   var styles = document.getElementById("allStyles").innerHTML += "p { color:red }";
   var text = styles.innerHTML;
   var styleNode = document.createElement('style');
   var styleText = document.createTextNode('p { color:red; } ');
   styleNode.appendChild(styleText);
   document.getElementsByTagName('head')[0].appendChild(styleNode);
   alert("ok");
};
function teso()
{
   google.script.run.withSuccessHandler(SuccessAddCss).includeCSS();
   alert(text);
};

In order to add somehow css from MainPageCSS to MainPage id="allStyles" type="text/css"

<pre>
<style id="allStyles" type="text/css">
h2{
font-family: Times New Roman, Times, serif;
font-size: 14px;
text-align: center;
}
</style>

</pre>

Also sidebar is launched in SandBox.Native mode, so it allows css dynamic changes. Thank you for help.

In my website, I use a scriptlet to include the CSS file.

HTML:

<?!= include('MainPageCSS'); ?>

<div>Some Content Here</div>
<form>A form</form>
<button>A button</button>

That's how the include function gets called from the HTML file. Just curious, could you try taking out the <pre> tags and see if that makes any difference?
