Styles Redux

In my last post, I touched on the ability to programmatically change styles in a web application. In today’s post, I want to visit another style property which the DOM exposes that comes in very handy. This property is visibility.

Many times in a web application you want to either hide or show content based upon the user and the experience you wish them to have. We can do this by accessing the visibility property. Let’s see how this works.

In CSS you can set an element to be either hidden or visible as follows:

[code lang=”css”]
#myElement {
visibility: hidden;

If you would like the ‘myElement’ element to be seen, you would change “hidden” to “visible”. Now how do we access this programmatically?

[code lang=”js”]
document.getElementById("myElement").style.visibility = "hidden";

As you can see, as long as we grab the element first, we then can access the style visibility property and set it to either visible or hidden.

Happy Coding!

Unlocking Wireless Communication: A Dive into the Bluetooth API

Wireless communication has become an integral part of our daily lives, and Bluetooth technology is at the forefront of this revolution, enabling devices to exchange data over short distances and creating a world more interconnected than ever before. At the heart of this technology lies the Bluetooth Application Programming Interface (API), a powerful tool for developers looking to harness the capabilities of Bluetooth in their applications. In this blog post, we’ll explore what the Bluetooth API is, how it works, and the possibilities it opens up for innovation in wireless communication.

Understanding the Beacon API: Simplifying Asynchronous Data Transfers

In today’s data-driven world, web applications often need to send data back to the server. Traditionally, this has been done using AJAX requests or similar methods. However, these techniques can come with a cost, especially when dealing with data that needs to be sent during the unload phase of a document, such as tracking and diagnostic data. This is where the Beacon API shines by allowing developers to send data to a server more reliably and efficiently.
