I'm using flex in tailwind CSS to design the above section. I have placed a background image of React logo in this section. I've tried to change the opacity of the background image through the "opacity-25" class of tailwind but it changes the opacity of the whole section.
Please suggest me a feasible solution for this problem.
Note: Linear gradient isn't applicable here as it will be applied to the whole footer and affect the entire background. I just want to change the opacity of React Logo. I'm using custom classes for "basis". Here "basis-40%" means 40% width of the column.

Answer 1

Although I have never used the tailwind class library, I suspect the css to override the opacity can be done the same way overriding any other value in css can be achieved. Define the selector class at a higher level in the initialization sequence, specify the property and new value and tell the interpreter that it is an important change.
The key takeaway here is the reserved word important which is applied after the new value. This is done by writing a space !important at the end of hte line. More about how !important works can be found at the following website:
