16 items.
-
-
A reading that surveys the full range of HTML input types and form elements (text, email, checkbox, select, etc.), helping learners understand which element to choose based on the kind of data being collected.
-
A reading covering how to use label elements, fieldsets, and legends to make forms accessible to all users, including those using assistive technologies, so learners can build inclusive form interfaces.
-
A reading explaining the action, method, and enctype attributes on the form element that control where and how submitted data is sent, helping learners understand the mechanics of form submission.
-
A reading that introduces HTML5's built-in validation attributes (required, pattern, min, max, minlength, etc.) and explains how to enforce input rules directly in markup without JavaScript.
-
A reading that goes beyond HTML5 built-in validation to cover writing custom JavaScript validation logic, including cross-field comparisons and dynamic error handling for real-world form requirements.
-
A reading focused on best practices for presenting validation error messages and feedback in ways that are clear, timely, and user-friendly, helping learners design forms that guide users to successful submission.

-
A foundational reading that explains what an HTML form is, how the <form> container groups controls like text boxes, checkboxes, radio buttons, and drop-down lists, and how the action and method attributes determine what happens on submission — used as the module's starting point before learners build their own forms.
-
A lesson surveying the core form elements (form, input, select, option, textarea, button, and label) with emphasis on how the input element's type attribute changes its behavior, giving learners a reference for choosing the right control for each kind of data.
-
A reading on form accessibility that shows how to associate label elements with controls explicitly or implicitly, and how fieldset and legend group related inputs so screen readers announce them correctly — learners apply these techniques to make their forms usable for everyone.
-
A lesson on how collected data actually reaches a server, covering the action, method (GET vs. POST), and enctype attributes and how they work together, so learners can correctly configure where and how their form submits.
-
A reading on browser-native validation using attributes such as required, minlength, maxlength, pattern, min, and max along with input types, showing learners how to enforce acceptable data and trigger built-in error messages without writing JavaScript.
-
A lesson on writing custom JavaScript validation for cases HTML5 attributes cannot handle — matching passwords, conditionally required fields, business-specific formats, and custom error wording — used by learners to extend validation beyond browser defaults.
-
A reading on validation user experience covering inline error messages placed beside the offending field, visual state indicators for valid and invalid input, and timing of feedback, so learners can design forms that clearly tell users what went wrong and how to fix it.
-
The consolidated module document that compiles all seven topic readings — forms basics, input types, labels and accessibility, submission attributes, HTML5 validation, custom JavaScript validation, and validation feedback — into a single continuous text for review or printing.
