How to skin the web front-end

With the popularity of the Internet, more and more websites are now paying attention to user experience, and the web page skinning function has become a way to improve user experience. Many websites provide skin-changing functions, but few websites open source code modifications. Therefore, in this article, I will introduce to you how the web front-end implements web page skin-changing functions.

1. CSS3 Variables

CSS3 Variables, also known as CSS variables, is a new CSS feature that can provide the same value for multiple CSS properties. CSS variables allow us to dynamically change the appearance of a web page by changing styles in different parts of the application.

For example, define a variable in CSS:

:root {
  --primary-color: #008080;
}

Then, you can use this variable in different selectors:

button {
  background-color: var(--primary-color);
}

h1 {
  color: var(--primary-color);
}

This way, you can change the root element by changing the --primary-color variable to dynamically change the color of all elements in the web page that use this variable.

2. JavaScript

JavaScript is versatile, and of course it can also be used to implement web page skinning functions. With JavaScript, we can dynamically change CSS styles between user requests.

For example, switch different themes by adding a CSS class:

function changeTheme(color) {
  var element = document.getElementById('page');
  element.classList.remove('theme-light', 'theme-dark');
  element.classList.add('theme-' + color);
}

The "color" parameter here is a string, which represents the theme color the user wants. Then, use JavaScript to add specified CSS classes to page elements, thereby changing the theme of the page.

3. Cookie

According to the theme selected by the user, we can also use cookies to record the user's preferences.

For example, when a user changes the default theme, we can use a cookie to record their choice:

function changeTheme(color) {
  var element = document.getElementById('page');
  element.classList.remove('theme-light', 'theme-dark');
  element.classList.add('theme-' + color);
  document.cookie = 'theme=' + color + ';path=/';
}

When the next time the page is opened, we can read the cookie and apply the user's preferences:

function applyTheme() {
  var theme = getCookie('theme');
  if(theme) {
    var element = document.getElementById('page');
    element.classList.remove('theme-light', 'theme-dark');
    element.classList.add('theme-' + theme);
  }
}

function getCookie(name) {
  var value = '; ' + document.cookie;
  var parts = value.split('; ' + name + '=');
  if (parts.length === 2) {
    return parts.pop().split(';').shift();
  }
}

Conclusion

There are many ways to implement the website skinning function on the Web front end, and the above are just a few examples. You can choose appropriate methods and technologies to implement relevant functions and achieve a good user experience.

In short, by implementing the website skinning function, users can improve the comfort and satisfaction when using the website, thereby improving the user experience quality of the website.
