Post pobrano z: Front-End Challenges

My favorite way to level up as a front-end developer is to do the work. Literally just build websites. If you can do it for money, great, you should. If the websites you make can help yourself or anyone else you care about, then that’s also great. In lieu of that, you can also make things simply for the sake of making them, and you’ll still level up. It’s certainly better than just reading about things!

Here’s some resources that encourage you to level up by building things for the sake of leveling up, if you’re up to it.

Carry’s advice is to start with a real-world object—the interface of a gaming console or a calculator, for example—and to try to recreate it using only CSS. “A great way to push the boundaries with a language is to make something that the language wasn’t meant to be doing in the first place,” he says.

Post pobrano z: Pseudo-Randomly Adding Illustrations with CSS

Between each post of Eric Meyer’s blog there’s this rather lovely illustration that can randomly be one of these five options:

Eric made each illustration into a separate background image then switches out that image with the nth-of-type CSS property, like this:

.entry:nth-of-type(2n+1)::before {
   background-image: url(image-1.png);
}

.entry:nth-of-type(3n+1)::before {
   background-image: url(image-2.png);
}

.entry:nth-of-type(4n+1)::before {
   background-image: url(image-3.png);
}

.entry:nth-of-type(5n+1)::before {
   background-image: url(image-4.png);
}

This seems like a good time to plug our very own little :nth Tester tool. It definitely helps me understand what something like (2n+1) means in English. You can type in any string you like and see what effect that has on your site:

Anyway, back to Eric’s post. As he mentions, his technique is pseudo-random in that it looks like a random image on the page but it technically isn’t. Either way, I think it’s a really lovely technique! And it certainly breaks up the visual monotony that happens when you’re looking at a website for too long.

Here’s what it looks like in practice:

Lovely stuff!

Another way to do this is to use random numbers in CSS. For example, we could set a variable in JavaScript and then apply it with CSS custom properties. Or we could put all the images in a single sprite file and change the background-position based on a random number.

This is definitely one of those things in CSS where there are no wrong answers; just different ways to do the same awesome thing!

Post pobrano z: Better Form Inputs for Better Mobile User Experiences

Here’s one simple, practical way to make apps perform better on mobile devices: always configure HTML input fields with the correct type, inputmode, and autocomplete attributes. While these three attributes are often discussed in isolation, they make the most sense in the context of mobile user experience when you think of them as a team. 

There’s no question that forms on mobile devices can be time-consuming and tedious to fill in, but by properly configuring inputs, we can ensure that the data entry process is as seamless as possible for our users. Let’s take a look at some examples and best practices we can use to create better user experiences on mobile devices.

Using the correct input type

This is the easiest thing to get right. Input types, like email, tel, and url, are well-supported across browsers. While the benefit of using a type, like tel over the more generic text, might be hard to see on desktop browsers, it’s immediately apparent on mobile.

Choosing the appropriate type changes the keyboard that pops up on Android and iOS devices when a user focuses the field. For very little effort, just by using the right type, we will show custom keyboards for email, telephone numbers, URLs, and even search inputs. 

One thing to note is that both input type="email" and input type="url" come with validation functionality, and modern browsers will show an error tooltip if their values do not match the expected formats when the user submits the form. If you’d rather turn this functionality off, you can simply add the novalidate attribute to the containing form.

A quick detour into date types

HTML inputs comprise far more than specialized text inputs — you also have radio buttons, checkboxes, and so on. For the purposes of this discussion, though, I’m mostly talking about the more text-based inputs. 

There is a type of input that sits in the liminal space between the more free-form text inputs and input widgets like radio buttons: date. The date input type comes in a variety of flavors that are well-supported on mobile, including date, time, datetime-local, and month. These pop up custom widgets in iOS and Android when they are focused. Instead of triggering a specialized keyboard, they show a select-like interface in iOS, and various different types of widgets on Android (where the date and time selectors are particularly slick). 

I was excited to start using native defaults on mobile, until I looked around and realized that most major apps and mobile websites use custom date pickers rather than native date input types. There could be a couple reasons for this. First, I find the native iOS date selector to be less intuitive than a calendar-type widget. Second, even the beautifully-designed Android implementation is fairly limited compared to custom components — there’s no easy way to input a date range rather than a single date, for instance. 

Still, the date input types are worth checking out if the custom datepicker you’re using doesn’t perform well on mobile. If you’d like to try out the native input widgets on iOS and Android while making sure that desktop users see a custom widget instead of the default dropdown, this snippet of CSS will hide the calendar dropdown for desktop browsers that implement it:

::-webkit-calendar-picker-indicator {
  display: none;
}

One final thing to note is that date types cannot be overridden by the inputmode attribute, which we’ll discuss next.

Why should I care about inputmode?

The inputmode attribute allows you to override the mobile keyboard specified by the input’s type and directly declare the type of keyboard shown to the user. When I first learned about this attribute, I wasn’t impressed — why not just use the correct type in the first place? But while inputmode is often unnecessary, there are a few places where the attribute can be extremely helpful. The most notable use case that I’ve found for inputmode is building a better number input.

While some HTML5 input types, like url and email, are straightforward, input type="number" is a different matter. It has some accessibility concerns as well as a somewhat awkward UI. For example, desktop browsers, like Chrome, show tiny increment arrows that are easy to trigger accidentally by scrolling.

So here’s a pattern to memorize and use going forwards. For most numeric inputs, instead of using this: 

<input type="number" />

…you actually want to use this:

<input type="text" inputmode="decimal" />

Why not inputmode="numeric" instead of inputmode="decimal" ? 

The numeric and decimal attribute values produce identical keyboards on Android. On iOS, however, numeric displays a keyboard that shows both numbers and punctuation, while decimal shows a focused grid of numbers that almost looks exactly like the tel input type, only without extraneous telephone-number focused options. That’s why it’s my preference for most types of number inputs.

Christian Oliff has written an excellent article dedicated solely to the inputmode attribute.

Don’t forget autocomplete

Even more important than showing the correct mobile keyboard is showing helpful autocomplete suggestions. That can go a long way towards creating a faster and less frustrating user experience on mobile.

While browsers have heuristics for showing autocomplete fields, you cannot rely on them, and should still be sure to add the correct autocomplete attribute. For instance, in iOS Safari, I found that an input type="tel" would only show autocomplete options if I explicitly added a autocomplete="tel" attribute.

You may think that you are familiar with the basic autocomplete options, such as those that help the user fill in credit card numbers or address form fields, but I’d urge you to review them to make sure that you are aware of all of the options. The spec lists over 50 values! Did you know that autocomplete="one-time-code" can make a phone verification user flow super smooth?

Speaking of autocomplete…

I’d like to mention one final element that allows you to create your own custom autocomplete functionality: datalist. While it creates a serviceable — if somewhat basic — autocomplete experience on desktop Chrome and Safari, it shines on iOS by surfacing suggestions in a convenient row right above the keyboard, where the system autocomplete functionality usually lives. Further, it allows the user to toggle between text and select-style inputs.

On Android, on the other hand, datalist creates a more typical autocomplete dropdown, with the area above the keyboard reserved for the system’s own typeahead functionality. One possible advantage to this style is that the dropdown list is easily scrollable, creating immediate access to all possible options as soon as the field is focused. (In iOS, in order to view more than the top three matches, the user would have to trigger the select picker by pressing the down arrow icon.)

You can use this demo to play around with datalist:

And you can explore all the autocomplete options, as well as input type and inputmode values, using this tool I made to help you quickly preview various input configurations on mobile.

In summary

When I’m building a form, I’m often tempted to focus on perfecting the desktop experience while treating the mobile web as an afterthought. But while it does take a little extra work to ensure forms work well on mobile, it doesn’t have to be too difficult. Hopefully, this article has shown that with a few easy steps, you can make forms much more convenient for your users on mobile devices.
