🙋 Introduction

The top property in CSS is used to specify the vertical position of a positioned element. This property works in conjunction with position values such as absolute, relative, fixed, or sticky.

By setting the top property, you can control the distance between the top edge of the element and the top edge of its containing element.

💡 Syntax

The syntax for the top property is straightforward and can be applied to any positioned element.

Syntax

Copied

element {
  position: position-value;
  top: value;
}

Here, position-value can be absolute, relative, fixed, or sticky, and value can be a length (e.g., px, em), a percentage (%), or other valid CSS units.

🎛️ Default Value

The default value of the top property is auto, which means the browser will calculate the top position of the element.

🏠 Property Values

Value	Description
length	Specifies the top position in length units such as px, em, rem, etc.
percentage	Specifies the top position as a percentage of the containing element's height.
auto	Default value. The browser calculates the top position.
initial	Sets the property to its default value.
inherit	Inherits the value from the parent element.

📄 Example

In this example, we'll position a box 50 pixels from the top of its containing element using the top property with position: absolute.

🖥️ Browser Compatibility

The top property is supported in all modern browsers, including Chrome, Firefox, Safari, Edge, and Opera. It is also supported in older browsers, making it a reliable property to use for positioning elements.
