How to use the offsetLeft property in JavaScript.
The offsetLeft property in JavaScript is used to get or set the horizontal offset of an element relative to its containing element.
The syntax for accessing the horizontal offset of an element using the offsetLeft property is as follows:
element.offsetLeft
Among them, the element is the element to obtain the horizontal offset.
Here is the syntax for setting the horizontal offset of an element using the offsetLeft property:
element.offsetLeft = value
The element is the element in which the horizontal offset needs to be set, and the value is the offset value to be set.
Please note that setting the horizontal offset of an element will only change its position on the page, not its position in the document flow. If you want to change an element’s position in the document flow, you can do so by setting the element’s position property to “absolute” or “fixed” and adjusting the top and left properties.

<!DOCTYPE html>
<html>
<body>
<div id="myDiv" style="position:absolute;left:50px;top:100px;width:200px;height:100px;background-color:yellow;"></div>
<script>
var div = document.getElementById("myDiv");
console.log(div.offsetLeft); // 输出50
div.offsetLeft = 100; // 将元素的水平偏移量设置为100
console.log(div.offsetLeft); // 输出100
</script>
</body>
</html>
In the above example, the horizontal offset of an element is obtained and modified by accessing and setting the offsetLeft property of a div element.
