在CSS中,position属性用于指定一个元素在文档布局中的定位方式。其中,position:relative是其中一种取值。
当一个元素被设置为position:relative时,它会被相对于它原来的位置进行定位。也就是说,该元素会保留其在文档流中的位置,并且可以通过top、right、bottom、left属性来调整它相对于原位置的偏移量。
相对定位的元素不会被其他元素覆盖,也不会覆盖其他元素。同时,它的定位是相对于其包含块的,而包含块通常是其最近的已定位祖先元素,如果没有已定位的祖先元素,则相对于初始包含块进行定位。
总之,position:relative是一种相对定位方式,它可以让元素相对于原来的位置进行微调,而不会影响到其他元素的布局。

The "position: relative" CSS property is used to position an element relative to its normal position. This means that the element will still take up the same space as it normally would, but it can be moved or shifted from its original position using the top, bottom, left, and right properties.
For example, if you have a div that has the "position: relative" property set, and you want to move it 10 pixels to the right, you would use the following CSS:
div {
position: relative;
left: 10px;
}
This would move the div 10 pixels to the right of its original position, while still maintaining its height and width.
One common use for the "position: relative" property is in creating dropdown menus. By setting the parent element to "position: relative" and the dropdown menu to "position: absolute", you can position the dropdown menu relative to the parent element and have it appear exactly where you want it.
Overall, the "position: relative" property is a useful tool for controlling the position and layout of elements on a webpage.
