![]() ![]() If you don’t like round-ups or find them inappropriate, please feel free to skip them. Instead of replacing the main articles, we will add round-ups on top of our regular schedule. Therefore, we’ve decided to add a couple of round-ups per month as a bonus to our regular articles. We are not big fans of lists either, but the format is useful and - if the resources are relevant - can be extremely helpful. We’ve tried our best to fuel the growing appetite of our readers for more advanced articles, but recently we’ve been receiving more requests for carefully selected, useful round-ups. We’ve also explored new formats and on weekends we’ve been publishing more inspirational pieces, leaving the in-depth articles to weekdays. We’ve been investing more resources in the quality and relevance of our articles. We have invited professionals and high-profile developers to write for us. We’ve been publishing fewer lists and more in-depth articles about design and Web development. Any name that starts with - is a CSS variable.Over the last year, Smashing Magazine has evolved. We usually define them in the :root selector. Declaring variables in CSS are pretty easy. The benefits of using variables are that we can declare a variable once and use it multiple times in a document. ![]() We’ll also use CSS variables in this example. And the second one will be responsible for the specific theme designs. The first stylesheet is responsible for all the default styles our website will have, like the font-sizes, viewport height-width, image sizes. Also Read: JavaScript Browser Object Model Styling Our Default CSSĪs you might have observed, we have two stylesheets tag in our HTML document. And finally, in the end, we are linking our script file. In our main body, we are using an image from Unsplash. We will use the IDs of theme switches to design the switches. You can also see we are using a data-theme custom data attribute to keep track of the theme selected. This blank href will be used to attach our theme designs. We have added the fonts in the header, default styles stylesheets, and a stylesheet link with a blank href. Sunt in culpa qui officia deserunt mollit anim id est laborum. Excepteur sint occaecat cupidatat non proident, In reprehenderit in voluptate velit esse cillum dolore eu fugiat Ut enimĪd minim veniam, quis nostrud exercitation ullamco laboris Tempor incididunt ut labore et dolore magna aliqua. Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod We are also using the Roboto font to style the document. Our body contains an image and some random texts. We have a simple header section with the name of our app and the buttons to change the themes. Building the MarkupĪs you can understand from the gif above, we are not using any high-level design. Now that we know the file structure, let's begin the coding. Now that you have a basic understanding of the data attributes, let's start building our Theme Switcher. We can access this using the below codes, let employee = document.getElementB圜lassName("employee-table") Suppose we want to access the identity attribute from before. We can access these attributes in JavaScript with dataset property. And the second point is that we cannot use any valid HTML attribute as a name for data attributes. Two things to keep in mind while creating a data attribute is that the value that is stored inside data attributes can only be of string type. ![]() We also have special HTML data tags in HTML 5.įor example, we can name data-identity to create a custom data attribute for employee ID. Any attribute that starts with data- is a custom data attribute. HTML5 introduced us to the concept of Custom Data Attributes. Before HTML5, we could have used class or IDs, but this is not an impressive solution. Let's take an example, suppose we have a list of employees and we want to save their IDs, which we can use to manipulate them using the DOM. There may be situations when we have to store some information associated with DOM elements. One thing I must explain before we start building the Markup is custom data attributes in HTML. We’ll implement this using the browser’s local storage. The selected theme will be stored in the browser and will apply the same theme even after reloading. Also, the theme switcher will be persistent. I am not going to focus a lot on the styles instead, we’ll try to understand the logic about creating it. In this article, we’ll be building a theme switcher like that. The theme switcher can also be used as a dark mode switcher. You might have noticed that nowadays many websites have a theme switcher on top of their website. ![]()
