CSS selects the first p in div

CSS Selects the First p in a div

In web development, we often need to style elements on a page. Sometimes we need to select specific child elements within an element for styling, such as selecting the first p element within a div. In this article, we’ll detail how to use CSS selectors to achieve this goal.

1. Use the :first-child pseudo-class to select the first p element

The :first-child pseudo-class selects the first child of an element. We can use this pseudo-class to select the first p element within a div.

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="UTF-8">
<title>CSS selects the first p in a div</title>
<style>
div p:first-child {
color: red;
}
</style>
</head>
<body>
<div>
<p>First p element</p>
<p>Second p element</p>
</div>
</body>
</html>

Output:


CSS selects the first p in a div

In the example above, we use the div p:first-child selector to select the first p element in a div and set its text color to red.

2. Use :nth-child to select the first p element

In addition to the :first-child pseudo-class, we can also use the :nth-child selector to select the first child element of an element.

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="UTF-8"> 
<title>CSS selects the first p in div</title> 
<style> 
div p:nth-child(1) { 
font-weight: bold; 
} 
</style> 
</head> 
<body> 
<div> 
<p>First p element</p> 
<p>Second p element</p> 
</div> 
</body> 
</html> 

Output:

CSS selects the first p in div

In the above example, we use the div p:nth-child(1) selector to select the first p element in a div and set its text to bold.

3. Using :first-of-type to Select the First p Element

In addition to the :first-child and :nth-child pseudo-classes, we can also use the :first-of-type selector to select the first child element of a specific type within an element.

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="UTF-8"> 
<title>CSS selects the first p in a div</title> 
<style> 
div p:first-of-type { 
text-decoration: underline; 
} 
</style> 
</head> 
<body> 
<div> 
<p>First p element</p> 
<p>Second p element</p> 
</div> 
</body> 
</html> 

Output:

CSS selects the first p in a div

In the example above, we used the div p:first-of-type selector to select the first p element within a div and underline it.

4. Selecting the First p Element Using :nth-of-type

Similar to the :nth-child selector, we can also use the :nth-of-type selector to select the first child element of a specific type within an element.

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="UTF-8"> 
<title>CSS selects the first p in div</title> 
<style> 
div p:nth-of-type(1) { 
color: blue; 
} 
</style> 
</head> 
<body> 
<div> 
<p>First p element</p> 
<p>Second p element</p> 
</div> 
</body> 
</html> 

Output:

CSS selects the first p in the div

In the above example, we used the div p:nth-of-type(1) selector to select the first p element in a div and set its text color to blue.

5. The difference between using :first-child and :first-of-type

While both :first-child and :first-of-type can select the first child element of an element, there are some subtle differences between them. :first-child selects the first child element of an element, while :first-of-type selects the first child element of a specific type within an element.

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="UTF-8"> 
<title>CSS Select the First p in a div</title> 
<style> 
div p:first-child { 
color: red; 
} 
div p:first-of-type { 
font-weight: bold; 
} 
</style> 
</head> 
<body> 
<div> 
<p>First p element</p> 
<span>First span element</span> 
<p>Second p element</p> 
</div> 
</body> 
</html> 

Output:

CSS Select the First p in a div

In the example above, we used both the :first-child and :first-of-type selectors to select the first p element and the first span element within a div, applying different styles to each.

6. The Difference Between Using :nth-child and :nth-of-type

Similar to the difference between :first-child and :first-of-type, :nth-child and :nth-of-type also have some subtle differences. :nth-child selects the nth child element of an element, while :nth-of-type selects the nth child element of a specific type within an element.

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="UTF-8"> 
<title>CSS selects the first p in div</title> 
<style> 
div p:nth-child(2) { 
color: green; 
} 
div p:nth-of-type(2) { 
font-style: italic; 
} 
</style> 
</head> 
<body> 
<div> 
<p>First p element</p> 
<p>Second p element</p> 
<span>First span element</span> 
</div> 
</body> 
</html> 

Output:

CSS Selects the First

In the example above, we use both the :nth-child and :nth-of-type selectors to select the second p element and the second span element within the div, applying different styles to them.

7. Using :nth-child to Select Odd and Even Elements

In addition to selecting child elements at specific positions, we can also use the :nth-child selector to select child elements at both odd and even positions.

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="UTF-8"> 
<title>CSS Selects the First p in a div</title> 
<style> 
div p:nth-child(odd) { 
background-color: lightblue; 
} 
div p:nth-child(even) { 
background-color: lightpink; 
} 
</style> 
</head> 
<body> 
<div> 
<p>First p element</p> 
<p>Second p element</p> 
<p>Third p element</p> 
<p>The fourth p element</p> 
</div> 
</body> 
</html> 

Output:

CSS selects the first p in a div

In the example above, we use the :nth-child(odd) selector to select the odd-numbered p elements in the div and set their background color to light blue; we use the :nth-child(even) selector to select the even-numbered p elements and set their background color to light pink.

8. Use :nth-of-type to select odd and even elements## 9. Use :nth-child to select a specific range of elements

In addition to selecting child elements in odd and even positions, we can also use the :nth-child selector to select child elements within a specific range.

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="UTF-8"> 
<title>CSS selects the first p in a div</title> 
<style> 
div p:nth-child(n+2):nth-child(-n+4) { 
color: purple; 
} 
</style> 
</head> 
<body> 
<div> 
<p>First p element</p> 
<p>Second p element</p> 
<p>Third p element</p> 
<p>Fourth p element</p> 
<p>Fifth p element</p> 
</div> 
</body> 
</html> 

Output:

CSS Selects the First

In the example above, we use the :nth-child(n+2):nth-child(-n+4) selector to select the second through fourth p elements in a div and set their text color to purple.

10. Use :nth-of-type to Select a Specific Range of Elements

Similar to the :nth-child selector, we can also use the :nth-of-type selector to select a specific range of child elements.

<!DOCTYPE html> 
<html lang="en"> 
<head> 
<meta charset="UTF-8"> 
<title>CSS selects the first p in div</title> 
<style> 
div p:nth-of-type(n+2):nth-of-type(-n+4) { 
font-size: 20px; 
} 
</style> 
</head> 
<body> 
<div> 
<p>First p element</p> 
<p>Second p element</p> 
<p>Third p element</p> 
<p>Fourth p element</p> 
<p>Fifth p element</p> 
</div> 
</body> 
</html> 

Output:

CSS selects the first p in a div

In the example above, we use the :nth-of-type(n+2):nth-of-type(-n+4) selector to select the second through fourth p elements in a div and set their text size to 20 pixels.
