Use the bg-position-[<value>] syntax to set the background position based on a completely custom value:
<div class="bg-position-[center_top_1rem] ..."> <!-- ... --></div>For CSS variables, you can also use the bg-position-(<custom-property>) syntax:
<div class="bg-position-(--my-bg-position) ..."> <!-- ... --></div>This is just a shorthand for bg-position-[var(<custom-property>)] that adds the var() function for you automatically.
Thiết kế phản hồi
Prefix a background-position utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:
<div class="bg-center md:bg-top ..."> <!-- ... --></div>Learn more about using variants in the variants documentation.
