HTML5 Forms: Dependable Tools in Our Toolbox

HTML5 Forms: Dependable Tools in Our Toolbox

The following content is excerpted from the book "HTML5 & CSS3 for the Real World, 2nd Edition" co-authored by Alexis Goldstein, Louis Lazaris and Estelle Weyl. This book is available in stores around the world, and you can also purchase the e-book version here.

We've written most of the page code and you now know almost everything about the new HTML5 elements and their semantics. But before we start designing the website's look (we're doing it in Chapter 7), we'll quickly leave the homepage of HTML5 Herald to check out the registration page. This will illustrate the functionality HTML5 provides in terms of web forms.

HTML5 Web forms introduce new form elements, input types, attributes, native verification and other form features. We have used many of these features in the interface for years: form validation, combo boxes, placeholder text, and more. The difference is that we had to turn to JavaScript to create these behaviors in the past; now they can be used directly in the browser. You just need to include properties in the tag to use them.

HTML5 not only makes form tagging easier for developers, but also for users. Since the browser handles client verification natively, there will be greater consistency between different websites, and many pages will load faster without all redundant JavaScript.

Let's get started!

Forms are usually the last thing developers include in their pages – many developers find forms boring. The good news is that HTML5 injects more fun into form encoding. At the end of this chapter, we hope you can expect to use form elements appropriately in your markup.

Let's start with normal HTML Our registration form:

<form id="register" method="post">
  <fieldset>
    <h1>注冊</h1>
    <p>我想收到您的優(yōu)秀出版物。</p>
  </fieldset>

  <ul>
    <li>
      <label for="register-name">我的名字是:</label>
      <input type="text" id="register-name" name="name">
    </li>
    <li>
      <label for="address">我的電子郵件地址是:</label>
      <input type="text" id="address" name="address">
    </li>
    <li>
      <label for="url">我的網(wǎng)站位于:</label>
      <input type="text" id="url" name="url">
    </li>
    <li>
      <label for="password">我希望我的密碼是:</label>
      <p>(至少6個(gè)字符,無空格)</p>
      <input type="password" id="password" name="password">
    </li>
    <li>
      <label for="rating">在1到10的范圍內(nèi),我對HTML5的了解程度是:</label>
      <input type="text" name="rating" id="rating">
    </li>
    <li>
      <label for="startdate">請從以下日期開始我的訂閱:</label>
      <input type="text" id="startdate" name="startdate">
    </li>
    <li>
      <label for="quantity">我想收到</label>
      <input type="text" name="quantity" id="quantity">
      <label for="quantity">份《The HTML5 Herald》。</label>
    </li>
    <li>
      <label for="upsell">也為我注冊《The CSS3 Chronicle》</label>
      <input type="checkbox" id="upsell" name="upsell" value="CSS Chronicle">
    </li>
    <li>
      <input type="submit" id="register-submit" value="提交">
    </li>
  </ul>
</form>

This example registration form uses form elements that have been available since the earliest version of HTML. This form provides users with clues about the expected data type in each field through the tags and p elements, so even your users on Netscape 4.7 and IE5 (just kidding!) can understand this form. It works, but it can certainly be improved.

In this chapter, we will enhance this form to include HTML5 form functionality. HTML5 provides new input types specific to email addresses, URLs, numbers, dates, and more. In addition, HTML5 also introduces properties that can be used with new and existing input types. These allow you to provide placeholder text, mark fields as required, and declare acceptable data types—all without JavaScript required.

We will introduce all newly added input types later in this chapter. Before that, let's take a look at the new form properties provided by HTML5.

How can I include CSS only on some pages? How can I include CSS only on some pages? Jun 11, 2025 am 12:01 AM

There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

What is 'render-blocking CSS'? What is 'render-blocking CSS'? Jun 24, 2025 am 12:42 AM

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
