Set My Input Boxes Semi-transparent

I couldn't find a way to render my input boxes semi-transparent. I have an image in the background. I mean only the background of my input boxes must be semi-transparent, not the t

Solution 1:

If you mean that there is a background image that you want to be able to see through your input boxes then you can just user rgba() when setting the background-color of an input:

input {
    background-color: rgba(255, 255, 255, 0.5);
}
