There is a lag in the loading of css stylesheets

We created a single-page company website that utilizes three different stylesheets connected to the index.html. By clicking a button, users can switch between these stylesheets resulting in changes to colors, images, and text colors.

However, Issue 1: The button only functions properly on the second click, skipping two stylesheets before applying the third one directly.

Issue 2: There is a delay in loading the stylesheets intermittently, causing the page to momentarily display in black and white with no styling before the correct stylesheet kicks in.

Is there a solution to these two problems to ensure smooth functionality?

Any assistance would be greatly appreciated. Thank you.

This is the complete code:

Answer №1

The primary issue stemmed from the click function triggered within the one, two, three functions. Simply remove the click part as shown below:

var one = function () {
    if ($(".head").attr("href") === "headstyles.css") {
      $(".head").attr("href", "headstyles2.css");
    }

    if ($(".feature").attr("href") === "whyusstyles.css") {
      $(".feature").attr("href", "whyusstyles2.css");
    }
    if ($(".testimonials").attr("href") === "carouselstyles.css") {
      $(".testimonials").attr("href", "carouselstyles2.css");
    }
    if ($(".ctr").attr("href") === "services&pricestyles.css") {
      $(".ctr").attr("href", "services&pricestyles2.css");
    }
    if ($(".footer").attr("href") === "footerstyles.css") {
      $(".footer").attr("href", "footerstyles2.css");
    }
};

Furthermore, the secondary issue arises due to the necessity for the browser to load your CSS before utilizing it. To address this, you must preload the CSS in the following manner:

  <link rel="stylesheet" type="text/css" href="./headstyles2.css">
  <link rel="stylesheet" type="text/css" href="./carouselstyles2.css">
  <link rel="stylesheet" type="text/css" href="./footerstyles2.css">
  <link rel="stylesheet" type="text/css" href="./services&pricestyles2.css">
  <link rel="stylesheet" type="text/css" href="./whyusstyles2.css">

  <link rel="stylesheet" type="text/css" href="./headstyles3.css">
  <link rel="stylesheet" type="text/css" href="./carouselstyles3.css">
  <link rel="stylesheet" type="text/css" href="./footerstyles3.css">
  <link rel="stylesheet" type="text/css" href="./services&pricestyles3.css">
  <link rel="stylesheet" type="text/css" href="./whyusstyles3.css">
