To get all the external CSS stylesheets links of a webpage using JavaScript, you can use the href property of each item in the document.styleSheets array-like list.

For example, if you want to get all links of the external CSS stylesheets of the google.com homepage.

You can do it like this,

TL;DR

// array to hold all css href's
const allCssStylesheetsLinks = [];

// get refernce to all stylesheets
const stylesheets = document.styleSheets;

// looping through each stylesheet
// and checksing if there is href property in each item
for (let i = 0; i < stylesheets.length; i++) {
  if (stylesheets[i].href) {
    allCssStylesheetsLinks.push(stylesheets[i].href);
  }
}

// logging the array of stylesheets links
console.log(allCssStylesheetsLinks);

Explanation

• First, we can define an array to hold all the external CSS stylesheets links

// array to hold all css href's
const allCssStylesheetsLinks = [];

• After that let's get a reference to the stylesheets

// array to hold all css href's
const allCssStylesheetsLinks = [];

// get reference to all stylesheets
const stylesheets = document.styleSheets;

Next, we can loop through each stylesheet and check if the href property is present in each of the styleSheets list items. If the href has a truthy value we push the href property value to the allCssStylesheetsLinks array.

It can be done like this,

// array to hold all CSS href's
const allCssStylesheetsLinks = [];

// get refernce to all stylesheets
const stylesheets = document.styleSheets;

// looping through each stylesheet
// and checking if there is href property in each item
for (let i = 0; i < stylesheets.length; i++) {
  if (stylesheets[i].href) {
    allCssStylesheetsLinks.push(stylesheets[i].href);
  }
}

Now all the href are available in the allCssStylesheetsLinks array.

// array to hold all css href's
const allCssStylesheetsLinks = [];

// get refernce to all stylesheets
const stylesheets = document.styleSheets;

// looping through each stylesheet
// and checksing if there is href property in each item
for (let i = 0; i < stylesheets.length; i++) {
  if (stylesheets[i].href) {
    allCssStylesheetsLinks.push(stylesheets[i].href);
  }
}

// logging the array of stylesheets links
console.log(allCssStylesheetsLinks);

That's it! 😃.
