# Ensure \<dt\> and \<dd\> elements are contained by a \<dl\>

Rule ID: dlitemUser Impact: seriousGuidelines: WCAG 2.0

In HTML, definition terms (`<dt>`) and their corresponding descriptions (`<dd>`) should be properly nested within a definition list (`<dl>`) to maintain semantic structure and ensure accessibility.

## About This Rule

This rule ensures that all `<dt>` and `<dd>` elements are children of a `<dl>` element, maintaining proper semantic structure and enhancing accessibility for users of assistive technologies.

## Why It Matters

Screen readers and other assistive technologies rely on correct HTML semantics to convey information accurately. When `<dt>` and `<dd>` elements are not enclosed within a `<dl>`, it can lead to confusion, making it difficult for users to understand the relationship between terms and their definitions.

## How to Fix

Ensure that all `<dt>` and `<dd>` elements are properly nested within a `<dl>` element:

- Wrap each set of `<dt>` and `<dd>` pairs inside a `<dl>` element.
- Ensure that each `<dt>` is immediately followed by its corresponding `<dd>`.
- Avoid placing `<dt>` or `<dd>` elements outside of a `<dl>`.

### Example

#### Incorrect

Definition terms and descriptions outside of a `<dl>`:

    <dt>Coffee</dt>
    <dd>A brewed beverage prepared from roasted coffee beans.</dd>
    <dt>Tea</dt>
    <dd>An aromatic beverage commonly prepared by pouring hot water over cured leaves.</dd>

#### Correct

Properly nested `<dt>` and `<dd>` elements within a `<dl>`:

    <dl>
      <dt>Coffee</dt>
      <dd>A brewed beverage prepared from roasted coffee beans.</dd>
      <dt>Tea</dt>
      <dd>An aromatic beverage commonly prepared by pouring hot water over cured leaves.</dd>
    </dl>
