Style Bootstrap Modal with CSS - html

Question

I am creating a bootstrap modal which will contain an image. Everything works perfectly, but for some reason, I cannot change the styling of the button whatsoever.
I have tried changing the color of the main button by calling its class in CSS. But it is not cooperating.

Answer 1

Use background instead of background-color. It is because there are some other classes like .btn-info which have properties like background-image with a linear-gradient value which affects the button and you have not overwritten it.
You might also want to override the border-color property so that the blue border is not being used for red button.
