I’m trying to create an input block that has a rectangular shape with a corner offset to the bottom right. I’ve tried using the ::after pseudo-element to achieve this form, but I can’t seem to get the expected result.

<label className="signIn-input">
 <ReactSVG src={email} className='signIn-input-img' />
 <input type="text" placeholder='Email' className='signIn-input-item' />
</label>

.signIn-input {
  display: flex;
  align-items: center;
  gap: 8.5px;
  border: 1px solid #A4A4A4;
  width: 100%;
  height: 56px;
  position: relative;
}

.signIn-input::after {
  content: '';
  position: absolute;
  bottom: -5px;
  right: -2px;
  width: 0;
  border-style: solid;
  border-width: 8px 0 8px 8px;
  border-color: transparent transparent transparent #A4A4A4;
  transform: rotate(45deg);
}

In my code, the ::after pseudo-element is supposed to apply a corner offset to the bottom right of the input block, but it doesn’t work as expected. How can I fix this problem and achieve the desired result?
