Lightbox is one popular way to overlay images on the web. When you click on an image, the Lightbox pops up with some form of animation and dims the background so your focus is on the image itself….

There are times you need to change an element’s CSS classes at runtime. But when changing classes, it’s sometimes best to apply style details conditionally. For example, imagine your view has a pager. Pagers are often used to navigate larger sets of items. When navigating, it can be helpful to show the user the page they’re currently on. The style of the item is conditionally set, based on the current page that’s being viewed.

A pager in this case may look something like this:

In this example, there are five pages. Only one of these pages is selected at a time. If you built this pager with Bootstrap, the selected page would have a CSS class named active applied. You’d want this class applied only if the page was the currently viewed page. In other words, you’d want to conditionally apply the active CSS class. Luckily, Vue provides a way to conditionally apply a CSS class to an element, which I’m going to demonstrate in this article.

To conditionally apply a CSS class at runtime, you can bind to a JavaScript object. To successfully complete this task, you must complete two steps. First, you must ensure that your CSS class is defined. Then, you create the class bindings in your template. I’m going to explain each of these steps in detail in the rest of this article.

Step 1: Define Your CSS Classes

Imagine, for a moment, that the five page items shown in the image above were defined using the following HTML:

<div id=”myApp”>
<nav aria-label=”Page navigation example”>
<ul class=”pagination”>
<li class=”page-item”><a class=”page-link” href=”#”>1</a></li>
<li class=”page-item”><a class=”page-link” href=”#”>2</a></li>
<li class=”page-item active”><a class=”page-link” href=”#”>3</a></li>
<li class=”page-item”><a class=”page-link” href=”#”>4</a></li>
<li class=”page-item”><a class=”page-link” href=”#”>5</a></li>
</ul>
</nav>
</div>

Notice that each page in this code snippet has a list-item element (<li …). That element references the page-item CSS class. In the code for this article, this class is defined in the Bootstrap CSS framework. However, if it weren’t defined there, it would be your responsibility to ensure that it was defined somewhere. The second CSS class is the one that’s most relevant to this article, though.

The active CSS class is used to identify the currently selected page. For this article, this CSS class is also defined in the Bootstrap CSS. As shown in the snippet above, the active class is only used in the third list item element. As you can probably guess, this is the CSS class that you want to apply conditionally. To do that, you need to add a JavaScript object.

Graphic Design for Adidas Predator by Gordon Reid

abduzeedoMar 25, 2019

Gordon Reid shared a beautiful graphic design project for Adidas and one of their most iconic soccer (football) boots in history, The Predator. Adidas London wanted to create a range of new print, digital and social ads to mark the relaunch of this historic boot along with the launch of two new boots, the X and Nemeziz.

Gordon worked with the strapline for each boot to create illustrated assets for each boot. Each created to compliment the culture, history and design of each of the boots. For Instance, the Predator played on more of a retro, bold and graphic feel, whereas the X artwork played on the enhanced speed element and Nemeziz was all about being agile. Each artwork was brought to life using a bold color palette and strong graphical elements that could be used throughout the advertising.

For those starting out learning Vue, there’s a bit of confusion over the difference between methods, computed properties and watchers.

Even though it’s often possible to use each of them to accomplish more or less the same thing, it’s important to know where each outshines the others.

In this quick tip, we’ll look at these three important aspects of a Vue application and their use cases. We’ll do this by building the same search component using each of these three approaches.

Methods

A method is more or less what you’d expect — a function that’s a property of an object. You use methods to react to events which happen in the DOM, or you can call them from elsewhere within your component — for example, from within a computed property or watcher. Methods are used to group common functionality — for example, to handle a form submission, or to build a reusable feature such as making an Ajax request.

You create a method in a Vue instance, inside the methods object:

new Vue({
el: “#app”,
methods: {
handleSubmit() {}
}
})

And when you want to make use of it in your template, you do something like this:

<div id=”app”>
<button @click=”handleSubmit”>
Submit
</button>
</div>

We use the v-on directive to attach the event handler to our DOM element, which can also be abbreviated to an @ sign.

The handleSubmit method will now get called each time the button is clicked. For instances when you want to pass an argument that will be needed in the body of the method, you can do this:

<div id=”app”>
<button @click=”handleSubmit(event)”>
Submit
</button>
</div>

Here we’re passing an event object which, for example, would allow us to prevent the browser’s default action in the case of a form submission.

However, as we’re using a directive to attach the event, we can make use of a modifier to achieve the same thing more elegantly: @click.stop=”handleSubmit”.

Now let’s see an example of using a method to filter a list of data in an array.

In the demo, we want to render a list of data and a search box. The data rendered changes whenever a user enters a value in the search box. The template will look like this:

<div id=”app”>
<h2>Language Search</h2>

<div class=”form-group”>
<input
type=”text”
v-model=”input”
@keyup=”handleSearch”
placeholder=”Enter language”
class=”form-control”
/>
</div>

<ul v-for=”(item, index) in languages” class=”list-group”>
<li class=”list-group-item” :key=”item”>{{ item }}</li>
</ul>
</div>

As you can see, we’re referencing a handleSearch method, which is called every time the user types something into our search field. We need to create the method and data:

new Vue({
el: ‘#app’,
data() {
return {
input: ”,
languages: []
}
},
methods: {
handleSearch() {
this.languages = [
‘JavaScript’,
‘Ruby’,
‘Scala’,
‘Python’,
‘Java’,
‘Kotlin’,
‘Elixir’
].filter(item => item.toLowerCase().includes(this.input.toLowerCase()))
}
},
created() { this.handleSearch() }
})

The handleSearch method uses the value of the input field to update the items that are listed. One thing to note is that within the methods object, there’s no need to reference the method with this.handleSearch (as you’d have to do in React).

Building a learnable website is much tougher than it sounds.

One thinks one’s design is clear and comprehensible; however, a design that might be obvious for you, might be perceived totally different by a user with a different set of experiences. Therefore, the goal is to design a clear user path that visitors can quickly pick up and understand.

Why Learnability Matters

Learnability has a strong correlation with usability. It is vital for users to quickly understand the layout and purpose of an application. Especially for web applications, providing an easy to learn interface is important. It is much more convenient to design an easy to understand mobile app compared with a web application; a mobile screen just doesn’t allow to provide a complex interface or let the user accomplish difficult tasks.

The speed of adoption is not the only criteria why learnability matters. A website that looks familiar and provides an understandable interface will result in a lower bounce rate. This is especially useful for websites that try to boost their conversion rate. A complex design scares users and they will resort to other tools that provide a clear interface. In the end, the goal of every website is to convert an occasional user into a repeated user and engage the user for interaction.

Learnability by Example

We can find loads of examples on the internet where learnability has been applied in the right way. Let’s take a look at the key elements of learnability in design…

Small Hints

A few days ago, I moved to Berlin and I had to fill in a form for calculating the cost for my European health insurance. Unfortunately, the form is only available in German, however, due to the great combination of visuals and text, I could perfectly understand what information they required. This is a great example of how an icon can reflect a possible answer.

Other small hints like a tooltip or default text can give a user an initial idea about how the interface can be used and what options are available. Let’s take the Twitter “Compose new Tweet” modal as an example. The design asks the user to tell what is happening. The initial response of a new user would be to input what just happened into the field. Besides that, when the user hovers one of the icons below the text field, a tooltip will appear telling the user what action the icon allows. In short, no space is wasted on adding text, the design speaks for itself.

Familiarity by Consistency

Google uses its own design system (Material Design) which is increasingly used across all of its products. Therefore, a call-to-action button will be the same across tools. Users who have used Gmail should recognize a lot of the elements when using Google Drive for the first time.

This familiarity eases the adoption process of a new interface as users are able to transfer their mental model of one product onto another. Especially for an older generation who didn’t grow up with computers, this familiarity is important as they tend to avoid change and learning new interfaces.

A mental model represents a person’s thought process for how something works. Mental models are based on incomplete facts, past experiences, and even intuitive perceptions. They help shape actions and behavior, influence what people pay attention to in complicated situations and define how people approach and solve new problems or interfaces.

A snippet from Susan Carey’s 1986 journal article about ‘Cognitive science and science education’.

You can find this familiarity also on blogs, but not that explicit as only certain elements are implicitly required. For example, the hamburger icon indicates a menu is hidden and can be unfolded by clicking the hamburger. Mostly, you’ll find a search icon on the right side of the navigation bar.

Also, the layout across blogs is quite consistent. A blog always consists of a header with clear navigation followed by some featured articles and then the body of the article. We, as users, became familiar with this concept so that a blog with a different layout will look, and feel strange to us.

Evidence of Actions

In addition to making sure actions are comprehensible, it’s also important to make sure the user has evidence of their actions; this helps to reinforce what reaction each operation produces throughout the journey.

To give you a simple example, when completing a form, you are shown a ‘thank you’ or a mail that indicates the completion. For a user, that is clear evidence they have used the interface correctly. Why does this matter? Providing feedback during the learning process helps a user to remember the interface better as he immediately learns what is possible or not. Proper feedback mechanisms can reduce the learning curve quickly and also help the user increase his efficiency while using the tool.

To give an example, instead of solely giving feedback upon submission of a form, let’s provide feedback along the way on a field per field basis. This can be as simple as showing a list of requirements for a password field: whenever the password meets one of the listed requirements, the requirement gets ticked off; when all requirements are met, the input field turns green indicating the user can move on to the next input field.

How to Measure Learnability?

Actually, it is not that difficult to design a solid process for measuring learnability. First of all, a key indicator for learnability is the bounce rate. Therefore, using Google Analytics is crucial to gain insights.

Besides Google Analytics, you can perform tests yourself with random test subjects: Provide an interface to your test subjects and give them five simple tasks to complete. For example, you have an online platform for creating and sending invoices, let your users perform the following tasks:

Create an invoice with one item;
Edit invoice;
Send invoice to receiver;
Track payment for the invoice;
Download completed invoice for personal bookkeeping.

Now, let your test subjects perform these simple tasks five times in a row with each time a day of rest. It is important to measure the time needed for completing each task. A design that provides good learnability capabilities should see an increase in efficiency while repeating tasks. After five repetitions it is normal to see stagnation as the user has reached the limits of efficiency (unless they are superhuman).

Many elements determine the learnability factor. Never take your design for granted, there is always room for optimization. Use these tips in practice and see how you can optimize the conversion rate of your design.
