You know those session timeout warnings that pop up in apps right before you get kicked out? Ever wanted to add one to your own Angular app? Well, today we’re doing exactly that. We’re building a real-time countdown timer with smooth animations, color-coded warnings, and a “time’s up” message your users can’t miss.
Have you ever felt like some of the dynamic expressions in your Angular component templates are a tangled mess? What if I told you we now have a cleaner, more modern way to handle dynamic classes, styles, and even complex interpolations, without the headache?
Hello and welcome to another Angular tutorial. In this example I’m going to cover how to create something that I need often, a toggle button. This type of button controls the visibility of some sort of associated content. We’ll look two main approaches, one where we use a class and some CSS to control the visibility, and another where we use conditional logic to insert content into or remove it from the DOM. We’ll also look at a couple of bonus variations with the class-based, CSS approach too.
