When did you last need use an animation feature in your application? It’s something you probably do on a regular basis, if not daily. With Angular, we have a powerful animation framework that we can leverage to do all sorts of crazy things. Sometimes, when using these animation features, we need to do things when the animation starts, or when it ends, or both. Well, good news for us – we have this ability in Angular.
I work in Angular every day and I build things that need to be animated or transitioned when interacted with. And, because of this, I’m thankful for the Animations module. There are so many useful features available that make life much easier. We’re going to look at two of these features in this post. First, we’re going to use the query() function to find and animate several items at once. Then, we’ll use the stagger() function to create a delay between the animations running on each of these items. Alright, let’s get to it!
As you probably already know, when you build apps today, you’ll likely need to use animations and transitions to enhance the UI where possible. With Angular’s animation framework we have access to some pretty powerful features which allow us to do things that may not be possible with CSS alone. In this post we’re going to look at a little, fun and crazy example using the Angular keyframes() animation function. Alright, let’s get to it!
When building things with Angular have you ever found yourself with the need to animate mark-up as it physically enters and leaves the DOM? This isn’t possible right? Actually, it is. In Angular we have access to a powerful animation framework. It’s packed with many features that just aren’t possible, at least at the moment, with CSS by itself. In this post we’re going to dive into one such feature, the ability to animate mark-up as it’s added and removed from the document with the :enter and :leave aliases. Alright, let’s get to it!
When you build stuff in Angular, you probably pretty quickly discover that you want to add animations and transitions. They are an important aspect to any application now-a-days right? They help make the overall user experience feel nicer and can help to make it more intuitive too. Many times, we can use CSS to handle these animations, but Angular has a powerful animation framework baked right in that allows us to do a lot more than what we can with plain ol’ CSS. Alright, let’s get to it!
When creating a modal or pop-up in an Angular application, accessibility can be easy to overlook. If you’re developing an app but you’re able to see, hear, and easily access and use different devices, it’s probably not top of mind for you. But it’s important. Our goal should be to make our apps available to as many people as possible. Making them accessible helps do just that. In this post, we’ll work on an existing demo application that we’ve created over several posts focused on the Angular CDK Overlay. We’ll take the example and make it accessible using ARIA roles and attributes, managing focus, and adding proper keyboard functionality. Alright, let’s get to it!
When using the Angular CDK Overlay module, you will likely want to transition the opening and closing of the overlay content. It’s something that seems like it should be pretty easy and straightforward but it’s actually a little tricky. It can’t really be transitioned with CSS only because it’s markup that gets added into and removed from the document. It’s not a simple style or class change. We need to leverage Angular animations to make it work well. In this post I’ll show you why and I’ll show you how to make animations work for your overlays. Alright, let’s get to it!
In the Angular CDK there are a lot of cool, exciting, and helpful features. And the Overlay Module is one of the most powerful. It’s used to create things like dialogs, tooltips, menus, custom dropdowns and more. I’ve already created a couple of posts on the Overlay Module, one where I cover the basics of setting them up, and another where I demonstrate different ways that they can be positioned within the viewport. If you’re unfamiliar with these concepts and haven’t read those, you should do that before rreading this one because we will build off the examples that we created in them. Here, we’ll be focused on how we want an overlay to react when scrolling the container it’s positioned within.
The Angular CDK Overlay is a handy, powerful, and fairly complex feature that can be used to quickly create modals and pop-ups. In my previous post about the CDK Overlay, I covered the basics needed to create both a modal using the global position strategy and a pop-up using the flexible connected to position strategy. I’d suggest that if you’re unfamiliar with the Overlay module at all, you go check out that post first because the demos in this video will build off the examples we built, and concepts that we learned. In this post we are going to learn about different ways to control how a pop-up gets positioned when using a connected overlay because there’s a lot to it and it’s all pretty cool.
When building apps in Angular, you will likely need to trigger a modal or pop-up at some point. Sometimes this is easy and can be done with some simple CSS, but other times, it may be more complicated. You may need to append markup to the bottom of your document so that it can be placed on top of everything else. Or maybe depending on scroll position, a pop-up will need to open upward instead of downward. There’s lot’s of possible scenarios where you may need more than what’s capable with CSS by itself and that’s where the CDK Overlay Module comes into play.
If you’re using dynamically created components in Angular, you’ve probably found it difficult to pass information between the parent and child components when needed. You need to provide the info in the parent and then inject it within the child component. While it’s not necessarily difficult to do, it results in a lot of extra boilerplate code. It would be so much better if we could just use the `@Input` decorator like we’re used to. Well, guess what? Angular supports doing this exact thing as of version sixteen. In this post, I’ll show you how. Alright, let’s get to it.
Centering items with HTML and CSS used to be pretty tough to do. Well, it’s not anymore. There are many different ways to do it now. And that’s a good thing because we may need different options in different scenarios. In this video we’ll look at three of my favorite ways to center items, We’ll use positioning, then we’ll use flexbox, and lastly, we’ll use my go-to CSS grid. Alright, let’s get to it.
A focus trap is a very important accessibility feature within a web application. In this post I’ll first help you understand what it is, then why it’s important, and finally I’ll show how to quickly and easily add the concept within your Angular apps where needed. And, it’s pretty easy thanks to the Angular CDK. Alright, let’s get to it.
We now have a new search element in HTML. It should be used when adding any sort of search functionality within a website or web app. Its purpose is to provide the proper semantics for search functionality within the browser. In this post I’ll show you how to use it in a couple of common search scenarios. Ok, let’s get to it.
In Angular 17 we have a couple of new ways to include styles within our components. In this post we’ll take a close look at these new features, and we’ll learn how to use them. Alright, let’s get to it!
Custom properties have been a pretty big deal for us who use CSS regularly. Many of us are probably starting to use them quite a bit, especially as part of a color or theming system. They really work great for this. But what about when we need alpha transparency for a color set with a custom property? Well, in this post I’ll show you how it works. Alright, let’s check it out!
Sometimes, in an Angular app we need to trigger something when the viewport gets resized. Like in the demo app for this post, when we open a menu, and then resize, we want to close the menu automatically. How would you do this? Well, maybe you have some ideas, but with the Angular CDK, this is pretty easy. We can use the Viewport Ruler. It’s a utility that deals with, you guessed it, the viewport. In this post I’m going to show you how to use it. Alright, let’s get to it!
You know what’s cooler than using an image when building a website? How about making something with HTML and CSS that looks and acts like an image? And you know what, this is super easy now with container queries. In this post we’re going to make an ad, that looks like an image, with HTML and CSS. Then we’re going to make it act like an image as it gets squished, expanded, and moved to other locations within the document. Ok, let’s check it out!
In the latest version of Angular, we’re getting what is known as the new Control Flow syntax for our component templates. It will replace older directives for things like *ngIf/else, ngSwitch, and *ngFor. In this post we’re going to learn exactly what this change means for us and how to use it. Alright, let’s get to it.
In this post we’re going to look at a really exciting new CSS feature, scroll driven animations. We’ll take some, boring, scrolling content, and give it an upgrade to something a little more interesting. And we’ll do it all with CSS. No JavaScript. Alright, let’s get to it!
