Multi-Million Dollar HTML

Two compelling case studies highlight significant financial losses stemming from seemingly minor HTML oversights:

• Chipotle's flawed online ordering: Jason Grigsby discovered a critical error in Chipotle's online ordering system. Their credit card expiration year input field uses an ineffective masking technique, rendering entries invalid and preventing orders. A simple fix using the native browser feature pattern="\d\d" maxlength="2" would have prevented this, resulting in an estimated $4.4 million loss, according to Grigsby's calculations.

• Accessibility failure costing millions: Adrian Roselli points to a pervasive accessibility issue: missing for/id attributes on form labels and inputs. This fundamental HTML error renders forms unusable for many, leading to an estimated $18 million loss in campaign conversions, based on Roselli's analysis.

The consistent neglect of proper label/input association is particularly concerning. This is foundational HTML knowledge crucial for both accessibility and optimal user experience. Despite its inclusion in every HTML curriculum, countless production websites continue to make this mistake.

Let's prioritize these essential HTML best practices! Correct implementation is simple:

<label for="name">Name:</label>
<input id="name" type="text">
