🙋 Introduction

The max-height property in CSS is used to specify the maximum height of an element.

This property is particularly useful when you want to restrict the height of an element but still allow it to grow if necessary, depending on its content. It's often used in conjunction with other properties such as overflow to handle content that exceeds the maximum height.

💡 Syntax

The syntax for the max-height property is as follows:

Syntax

Copied

element {
  max-height: value;
}

Here, value can be a length (such as px, em, rem, vh, etc.), a percentage, or the keyword none.

🎛️ Default Value

The default value of the max-height property is none, which means there is no maximum height restriction on the element.

🏠 Property Values

Value	Description
length	Specifies a fixed height, such as 200px, 10em, 50vh.
percentage	Specifies a height relative to the height of the containing element, such as 50%.
none	No maximum height is applied, meaning the element can grow indefinitely.

📄 Example

In this example, we’ll restrict the maximum height of a div element to 200 pixels. If the content exceeds this height, it will be clipped or scrollable depending on the overflow property.

  <style>
    .container {
      max-height: 200px;
      overflow: auto; /* Adds a scrollbar if content exceeds max-height */
      border: 1px solid #ccc;
      padding: 10px;
    }
  </style>
</head>
