Input unclickable

Question

I don't know why but my input is unclickable. I saw there were a conflict with class class="cta-inner text-center rounded" but i would like to keep the design of this class. If anyone have an idea

body {
  font-family: 'Lora';
  background: -webkit-gradient(linear, left top, left bottom, from(rgba(47, 23, 15, 0.65))), url("../img/bg.jpg");
  background: linear-gradient(rgba(47, 23, 15, 0.65)), url("../img/bg.jpg");
  background-attachment: fixed;
  background-position: center;
  background-size: cover;

Answer 1

Try setting the inputs position to relative:

.cta .cta-inner input{
    position: relative;
}

The CSS .cta .cta-inner:before is overlapping the inputs, that's why you can't click them. With the change of the position of the inputs they are clickable again. Check out this Fiddle

Removing .cta .cta-inner:before from your CSS will alter the style since you won't have your double border design:

Answer 2

Your CSS is causing a div in front of your input.
Due of this your input is not clickable.
This is your wrong css block.

.cta .cta-inner:before {
border-radius: 0.5rem;
content: '';
position: absolute;
top: -0.5rem;
bottom: -0.5rem;
left: -0.5rem;
right: -0.5rem;
border: 0.25rem solid rgba(255, 255, 255, 0.85);
}

Just remove this, as its not used and not visible for the user.
Then it should be fixed!
