remove unused css

[SushanGhimire]

class is from flex.css is causing issues on my system since the text-center is reserved class on tailwindcss I also went through your code and I found it is not being used. so it will be better for tailwindcss users if this class is removed or renamed.

.text-center {
display: flex;
justify-content: center;
flex-direction: column;
text-align: center;
}
