I am adding some ‘lorem ipsum’ text for this purpose. Next, we need to add some demo text to the HTML. The reason for using the checkbox here is to style it and use it as the toggle switch. We assign an id with the name ‘toggle’ to this checkbox. Let us create a ‘div’ element with the class name ‘container’. Do copy the code I have provided below and paste it into your HTML file. You can check out that video here below.Ĭreate an HTML file and save it by the name – “index.html”. I have a video tutorial on this topic on my youtube channel. The javascript code we use is not too complicated so, you don’t have to worry about it. For this tutorial, we need HTML, CSS & Vanilla Javascript. We will cover them shortly in this tutorial. There are some do’s and don’ts when it comes to the dark theme in UI design. With this tutorial, you will get a basic idea of how you can add a dark theme option to your website without changing much code or without adding excessive CSS. When the user clicks on this switch, the theme of the webpage/website toggles between dark and light mode. In today’s tutorial, we will learn how to create a dark mode switch. One of the major reasons for this is to avoid strain on the eyes due to high brightness and provide them safety, especially in not so illuminated spaces. It has been a trending feature for the past few years. light-theme class inside of that we can use to override the dark mode properties, should the user want to toggle between the two modes.Dark theme is one of the most important aspects of website design. The idea is to define the custom properties for both themes like we did before, wrap dark styles up in the prefers-color-scheme media query, then define a. Let’s use the CSS custom properties approach to demonstrate how to do this. That’s why providing a way to manually override dark mode, despite the system settings, is a good idea. But what if users want to override their system preference for a site? Just because a user prefers dark mode for their OS doesn’t always mean they prefer it on a website. We just looked at how to account for a user’s system-wide color scheme preferences. There may even be other possible methods than what we have discussed. Sometimes a combination of methods will be the most effective route. Moreover, there’s nothing saying we can only use one method. On the other hand, if your project needs to support legacy browsers, then another approach will need to do instead. If you are doing a large project, for example, you might go with CSS properties to help wrangle a large codebase. The “right” method comes down to the requirements of your project. But a server-side solution like this is useful in persisting the user’s theme choice across page reloads, as we will see later. This method has an obvious downside: the page needs to be refreshed for the toggle to take place. I am using a GET request (URL params) for the purpose of this demonstration.Īnd, yes, we can swap stylesheets just like we did in the second method. Then, we let our code (PHP in this case) apply the appropriate body class when the page is reloaded. We can have the user send a GET or POST request. This is a great approach if you prefer working directly in the markup. If we’re already working with a server-side language, say PHP, then we can use it instead of JavaScript. Here’s a script for a button that will toggle that class, for example: // Select the buttonĬonst btn = document.querySelector('.btn-toggle') ītn.addEventListener('click', function(). The trick here is to swap out a class that can be a hook for changing a style anywhere on the page.
