What is preventing the 'p:nth-child(1)' from functioning properly in my HTML code?

Even though I used p:nth-child(1){color: white;} in my CSS style tag, it did not produce the expected result.

body {
  background-color: #162b85;
}

button,
p:nth-child(1) {
  color: white;
}

<p class="center">Register your account</p>
<div class="container">
    <button type="submit" class="color">Sign up</button>
  <p class="center">Already have an account? <a href="#">Sign
    in</a>.</p>
</div>

I noticed that the first p tag in the HTML code remained black instead of turning white as I expected. It made me wonder if the br tag was causing this issue. After removing the br tag from the body element, the color of the p tag changed to white as desired.

Answer №1

There could be a potential issue with the div tag causing some problems. The :nth-child() selector is utilized to choose the nth child of its parent element, regardless of its nature. In this scenario, if the div tags are the initial child elements of their parent, they will be selected instead of the p tags.

To resolve this problem, consider using the :first-of-type selector rather than :nth-child(1). This selector chooses the first child element of its type** within the parent element. Check out the example below:

div p:first-of-type {
  color: white;
}

This code snippet targets the first p element that is a child of a div element and changes its text color to white.

Answer №2

Your CSS issue stems from how the :nth-child pseudo-class selector functions. When you use p:nth-child(1), it targets a <p> element that is the first child of its parent. However, in your HTML structure, the first <p> comes after a <br /> tag, making it the second child.

In your case, within the body element, the first child is actually the <br /> tag, not the <p>. Removing the <br /> tag will make the <p> the first child and allow your CSS to correctly apply white color to it.

To address this issue, consider using the :first-of-type selector instead. This selector targets the first occurrence of a specific element type within its parent, disregarding its position among siblings. Update your CSS like so:

p:first-of-type {
  color: white;
}

With this selector, the white color will be applied to the initial <p> element regardless of any preceding elements.
