What is the best way to efficiently include multiple stylesheets and bootstrap libraries in one go within an HTML file?

Question

What is the best way to efficiently include multiple stylesheets and bootstrap libraries in one go within an HTML file?

I am currently in the process of creating a website that consists of approximately 100 pages. Each page contains similar code within the head section of the HTML files.

    <!--CSS imports-->
    <link rel="stylesheet" type="text/css" href="../PrimaryCSS.css">
    <link rel="stylesheet" type="text/css" href="../NavigationBarCSS.css">
    <link rel="stylesheet" type="text/css" href="../FooterCSS.css">

    <!--Bootstrap imports-->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <script src="../bootstrap-3.3.4-dist/jquery/1.11.1/jquery.min.js"></script>
    <link rel="stylesheet" href="../bootstrap-3.3.4-dist/css/bootstrap.min.css">
    <script src="../bootstrap-3.3.4-dist/js/bootstrap.min.js"></script>

    <!--HTML Imports for footer and navigation bar-->
    <script src="../fileLoaderMain.js"></script>

The Challenge:
One major issue I face is the need to manually update each file if I want to modify the bootstrap libraries or add/remove stylesheets. This process becomes repetitive and time-consuming.

The Inquiry:
I am seeking a solution that allows me to consolidate this repeated information into one file, which can be referenced by a single line like

<script> src="importHead.js" </script>

to automatically include all necessary components in the head section.

For instance, within the "fileLoaderMain.js" file, I have created functions in JavaScript to import the HTML elements for the navigation bar and footer. These functions appear as follows:

$(function () {
    $("#navbarComponentMainPagesID").load("../navbarComponentMainPages.html");
});
$(function () {
    $("#footerComponentID").load("../footerMainComponent.html"); 
});

In the HTML file, I can simply call these functions to import the navigation bar and footer by including corresponding divs like so:

<div id="navbarComponentMainPagesID"></div>
<div id="footerComponentID"></div>

This method enables me to make any changes to the navigation bar or footer in just one location.

Previous Attempts:
My initial approach involved using JavaScript functions to address the current issues encountered. However, my attempt failed when trying to import all necessary resources (stylesheets and libraries) via a single call in the main HTML file. I suspect that it was unsuccessful because importing JavaScript and jQuery files through div tags may not be supported.

While I believe this could be a relatively straightforward problem to solve, my experience with complex web development tasks is limited.

If you're looking to add multiple stylesheets dynamically, you can use a function like the one below:

let stylesheets = [
  'http://link-to-stylesheet-.com/css?family=somethingsomethingsomething',
  'http://link-to-stylesheet-.com/css?another-stylesheet',
  'http://link-to-stylesheet-.com/css?family=someding',
  'http://link-to-stylesheet-.com/css?someotherstylesheet',
  'http://link-to-stylesheet-.com/css?stylesheetnumber100'
];

function createStylesheet( href ) {
  let link = document.createElement('link');
  link.type = 'text/css';
  link.rel = 'stylesheet'
  link.href = href;
  return link;
}

// Loop through the array of stylesheets and create corresponding links
const appendStylesheets = stylesheets.map(function (sheet) {
  const createdLink = createStylesheet(sheet);
  return createdLink;
});

// Append each stylesheet link to the head of the document
appendStylesheets.forEach(function (link) {
  document.getElementsByTagName('head')[0].appendChild(link);
});

To ensure proper functionality, it is recommended to create a separate header.html or header.php file for loading with backend/frontend language integration.

Your javascript implementation seems solid. While I personally prefer binding with backend, the javascript method is also valid. However, the issue lies in not creating valid objects to add into the Document Object Model (DOM). Here's an example:

CSS How to load up CSS files using Javascript?

var cssId = 'myCss';  // Encode css path itself for id generation
if (!document.getElementById(cssId))
{
    var head  = document.getElementsByTagName('head')[0];
    var link  = document.createElement('link');
    link.id   = cssId;
    link.rel  = 'stylesheet';
    link.type = 'text/css';
    link.href = 'http://website.com/css/stylesheet.css';
    link.media = 'all';
    head.appendChild(link);
}

Loading JavaScript with jQuery Load JavaScript dynamically

$.getScript('http://maps.googleapis.com/maps/api/js?libraries=geometry&sensor=true', function(data, textStatus){
   console.log(textStatus, data);
   // Perform desired actions here
});

Pure JavaScript solution

var script = document.createElement('script');
script.src = something;
script.onload = function () {
    // Execute script-related tasks
};

document.head.appendChild(script);

Avoid using object tags as they are defined within the body element and might lead to SEO and validation issues.

HTML import provides a native solution within HTML:

<link rel="import" href="http://example.com/elements.html">

Unfortunately, its support is limited to Chrome and Opera browsers.

Given this limitation, I find it more preferable to utilize PHP for importing specific template parts using include 'filename' or require'filename'. This approach offers enhanced cleanliness and ease of maintenance.
