Mobile Webkit form tips

One of the things I really hate when I surf from a tablet/phone browser (usually my iPad/iPhone) is filling in forms. I know, the lack of a physical keyboard sucks big time, but it’s not just that. Most web developers out there don’t give the appropriate attention when they develop web forms, and the combination of both these things can literally destroy the good will of a user who’s trying to fill in the form. The use of some very basic attributes can change the above situation dramatically. You don’t believe me? Well have a look…

Keyboard Layout

One of the most important and easy fixes is to provide the correct keyboard layout. Well that’s super easy, just use the appropriate HTML5 input type. You’ll make many tablet/mobile users happier!

Autocorrect and AutoCapitalize

OK, let’s admit it, autocorrect is a cool feature when writing an e-mail, but it’s probably the worst one when you try to write your username (and iOS is correcting it over and over again). The exact same issue is caused with the autocapitalization. Well, nothing to worry about. Just use the below attributes to turn on and off the features from the elements you want. Now you’re in control of things 😉

Please try not to be lazy when you build forms, you might save a tablet/phone user’s time and sanity!

The above markup works fine on Android devices as well (and probably on Windows Phones), although I only test them on iOS iPhone/iPad devices…

Safari’s HTML5 search input

The safest and easiest way to upgrade your markup to HTML5 is to use the new form input types. They will appear as ordinary text inputs on older browsers, and at the same time they’ll save you tons of work on form validation, and as a bonus they’ll assist your users in filling them (by providing more in-browser features, alternate keyboard layouts and more). This blog theme uses a search input to search the site.

<input id="s" name="s" type="search" />Check out this Pen!

It works great, but unfortunately, Safari’s default search input generates a close button (x) into the input field (while you type). Supposedly this will help the users to view recent search keywords, but if they they decide that they don’t need help, they can just click it and remove everything from list and the input field. I didn’t need this in-browser style for my search input, so after an investigation, I discovered the below solution.

input[type="search"] {
  -webkit-appearance: textfield;
}Check out this Pen!

This rule will transform your search input (with the strange close button) into a typical text field input that you can style properly.

A really simple HTML5 template

Lately I’m using more and more HTML5 elements on my markup. It’s the right thing to do after all, especially on smaller, flexible projects. But as a typical developer I’m too lazy to type everything from scratch, that’s why I’m using more and more the HTML5 Boilerplate from Paul Irish. It’s great but I catch myself deleting many files and lines of code every time, in order to make Boilerplate fulfil my requirements. After all, in most cases I don’t really need things like YUI Profiler, Google Analytics, favicons/iPhone icons and many others for a quick prototype. What I really need, is a very simple template with less features, scripts, and tools! Below you can see/use my HTML5 Boilerplate

Markup :

<!DOCTYPE html>  
<html lang="en">  
<head>  
<meta charset="utf-8" />  
<title>Really simple HTML5 template</title>  
  
<link rel="stylesheet" type="text/css" href="style.css" />  
  
<!--[if lt IE 9]><script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script><![endif]-->  
</head>  
<body>  
    <h1>HTML5 Template</h1>  
</body>  
</html>Check out this Pen!

A single stylesheet and just one script, will do the work just fine. (The html5shiv helps older IE browsers, to style the new HTML5 elements).

How to attach a custom apple iPhone/iPad icon to your website

If you already have an iPhone, iPad or any other iOS-based device, you have definitely seen the strange bookmarking Safari option “Add to home screen“. The specific option creates an application like bookmark to your iOS screen for quicker browsing.

Clever idea and it works great, but if the site you’ve just bookmarked doesn’t have a custom iOS icon, iOS adds a poor quality screenshot of the site for icon! But don’t worry the solutions to this problem are super easy.

Just create a 57 x 57 pixels PNG (for iPhone, or 114 x 114 for iPhone 4 or 72 x 72 for iPad) with your custom icon, name it apple-touch-icon.png and put it into the root directory of your site. That’s it! You don’t even have to worry about the rounded corners of the PNG image, since iOS is clever enough to add them for you! The final URL of your icon must be something like http://www.yoursite.com/apple-touch-icon.png. If you want to supprt all iOS devices a 114 x 114 will do the job, although iPhone classic and iPad will scale it down.

Now if you don’t have access to the root directory of the site (no way!), or simply you don’t want to mess things up there, you have an alternative. Just put it wherever you like (maybe into the images/icons folder), and point to it with the below markup:

<link rel="apple-touch-icon" href="/images/mycustomiphoneicon.png" />Check out this Pen!

 

The above code must be placed in the head section of our document and it must have a link relation (rel) with the value “apple-touch-icon“, that’s the only two requirements. As you noticed we can name our PNG file as we want. Finally, yes we can use absolute paths as well, or even load our icon from other domains!

<link rel="apple-touch-icon" href="http://www.othersite.com/images/mycustomiphoneicon.png" />Check out this Pen!

 

Beginning HTML ordered lists with numbers other than 1

Yes it is possible and easy! You only have to use the (rare/unknown?) start attribute at your ordered list element (see example below).

<ol start="4">  
    <li>list item 1</li>  
    <li>list item 2</li>  
    <li>list item 3</li>  
    <li>list item 4</li>  
    <li>list item 5</li>  
</ol> Check out this Pen!

And guess what? It works with negative numbers as well!
