Answer 2

your css code does not seems to have any problem. Try adding box-shadow property.

.gs_tti50:focus {
  padding: 0px !important;
  border: 1px solid #FF0000;
  border-radius: 20px;
  box-shadow: inset 0 1px 1px rgba(0, 0, 0, 0.075), 0 0 8px rgba(255, 0, 0, 0.6);
  outline: none;
}

.gsc-i-id1 {
  height: 33px !important;
  padding: 0px !important;
  text-indent: 10px !important;
  background: white;
  border-radius: 20px;
}

<input class="gs_tti50" type="text">

Side note: If possible avoid using !important with css properties. More info: Is it bad to use !important in css property
