NEW QUESTION # 27
Which code segment creates a slider field that accepts a numeric value ranging from 1 through 10?

  • A.
  • B.
  • C.
  • D.

Answer: D

Explanation:
To create a slider field that accepts a numeric value ranging from 1 through 10, the input element with type=" range" should be used. The min and max attributes define the range of acceptable values.
* HTML Input Type range:
* Purpose: The range type is used for input fields that should contain a value from a specified range.
* Attributes:
* type="range": Specifies that the input field should be a slider.
* min="1": Sets the minimum acceptable value.
* max="10": Sets the maximum acceptable value.
* Example:
* Given the HTML:
<input type="range" name="sat-level" min="1" max="10">
* Options Analysis:
* Option A:
<input type="number" name="sat-level" max="10">
* This creates a numeric input field, not a slider.
* Option B:
<input type="range" name="sat-level" min="1" max="10">
* This is the correct option that creates a slider field with the specified range.
* Option C:
<input type="number" name="sat-level" min="1" max="10">
* This creates a numeric input field, not a slider.
* Option D:
<input type="range" name="sat-level" max="10">
* This creates a slider but lacks the min attribute, so it doesn't fully meet the requirement.
* References:
* MDN Web Docs - <input type="range">
* W3Schools - HTML Input Range
By using the correct attributes, the slider field will allow users to select a value between 1 and 10.
