Ví dụ
Ví dụ cơ bản
Sử dụng các tiện ích như brightness-50 và brightness-100 để kiểm soát độ sáng của một phần tử:
brightness-50
brightness-100
brightness-125
brightness-200
<img class="brightness-50 ..." src="/img/mountains.jpg" /><img class="brightness-100 ..." src="/img/mountains.jpg" /><img class="brightness-125 ..." src="/img/mountains.jpg" /><img class="brightness-200 ..." src="/img/mountains.jpg" />Sử dụng giá trị tùy chỉnh
Use the brightness-[<value>] syntax to set the brightness based on a completely custom value:
<img class="brightness-[1.75] ..." src="/img/mountains.jpg" />For CSS variables, you can also use the brightness-(<custom-property>) syntax:
<img class="brightness-(--my-brightness) ..." src="/img/mountains.jpg" />This is just a shorthand for brightness-[var(<custom-property>)] that adds the var() function for you automatically.
Responsive design
Prefix a filter: brightness() utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:
<img class="brightness-110 md:brightness-150 ..." src="/img/mountains.jpg" />Learn more about using variants in the variants documentation.
