HTML5 Form Input Features

HTML5 introduces a few good features for input fields. This will reduce the work of web developers, while developing web sites. Previously, we used javascript for checking the mandatory fields and validating email fields and so on. Now, with new attributes for input fields, inbuilt form validation is possible.

Here, we can see few most usable features.

HTML5 Form Input Features-Email Inputs

The first HTML5 Form Input Features we’ll discussis ‘Email’ attribute. We can use type=”email” for inputs in our form. By applying this attribute, we can instruct the browser to only allow strings that conform to a valid email address structure. The form validation from browser side/ built-in form validation happens when we submit the form. The following screenshot shows the error message.

<input id="email" name="email" type="email" placeholder="example@example.com" />
