--description--

It is important to link each input to the corresponding label element. This provides assistive technology users with a visual reference to the input.

This is done by giving the label a for attribute, which contains the id of the input.

This section will take a student's name, email address, and date of birth. Give the label elements appropriate for attributes, as well as text content. Then, link the input elements to the corresponding label elements.

--hints--

You should give the first label element an appropriate for attribute.

assert.isAtLeast(document.querySelectorAll('label')?.[0]?.htmlFor?.length, 1);

You should give the second label element an appropriate for attribute.

assert.isAtLeast(document.querySelectorAll('label')?.[1]?.htmlFor?.length, 1);

You should give the third label element an appropriate for attribute.

assert.isAtLeast(document.querySelectorAll('label')?.[2]?.htmlFor?.length, 1);

You should give the first label element an appropriate text content.

assert.isAtLeast(document.querySelectorAll('label')?.[0]?.textContent?.length, 1);

You should give the second label element an appropriate text content.

assert.isAtLeast(document.querySelectorAll('label')?.[1]?.textContent?.length, 1);

You should give the third label element an appropriate text content.

assert.isAtLeast(document.querySelectorAll('label')?.[2]?.textContent?.length, 1);

You should give the first input element an id attribute matching the for attribute of the first label.

assert.equal(document.querySelectorAll('input')?.[0]?.id, document.querySelectorAll('label')?.[0]?.htmlFor);

You should give the second input element an id attribute matching the for attribute of the second label.

assert.equal(document.querySelectorAll('input')?.[1]?.id, document.querySelectorAll('label')?.[1]?.htmlFor);

You should give the third input element an id attribute matching the for attribute of the third label.

assert.equal(document.querySelectorAll('input')?.[2]?.id, document.querySelectorAll('label')?.[2]?.htmlFor);

You should not use the same id attribute for more than one input element.

const id = (n) => document.querySelectorAll('input')?.[n]?.id;
assert.notEqual(id(0), id(1));
assert.notEqual(id(0), id(2));
assert.notEqual(id(1), id(2));

You should not use the same for attribute for more than one label element.

const htmlFor = (n) => document.querySelectorAll('label')?.[n]?.htmlFor;
assert.notEqual(htmlFor(0), htmlFor(1));
assert.notEqual(htmlFor(0), htmlFor(2));
assert.notEqual(htmlFor(1), htmlFor(2));
