You can use html required, autofocus and pattern attribute with RegExp ^[a-zA-Z]+(?:\s[a-zA-Z]+$|$) to match one or more a-z characters case insensitive at beginning of input, followed by space character, followed one or more a-z characters case insensitive by end of input, or end of input to handle two first names, for example "Billy Joe", "Norma Jean", "Sarah Jane"; <label> element adjacent to <input> element; css :invalid, :valid, :before; :after.

When input is :invalid set border to red, outline to none; set adjacent label element :before content of to "das", label :after content to !; at :valid:focus set label :before content to "First Name", label :after to UTF-8 "CHECK MARK"

@charset "UTF-8";
#input {
  height: 3.14em;
  left: 0px;
  outline: none;
  padding: 6px;
  margin: 4px;
  width: 150px;
#input:valid {
  border: 1px solid green;
  box-shadow: .015em .015em .015em green;
#input:invalid {
  border: 1px solid red;
  box-shadow: .015em .015em .015em red;
#input:invalid + [for="input"]:before {
  content: "das";
#input + [for="input"]:after {
  font-weight: bold;
  left: 160px;
  top: 12px;
  position: absolute;
#input:invalid + [for="input"]:after {
  content: "!";
  color: red;
#input:valid + [for="input"]:after {
  content: "\2713";
  color: green;
#input:valid + [for="input"]:before {
  content: "First Name";
  color: #ccc;
label[for="input"]:before {
  position: absolute;
  left: 12px;
  padding: 6px;
<meta charset="UTF-8" />
<input id="input" type="text" pattern="^[a-zA-Z]+(?:\s[a-zA-Z]+$|$)" required autofocus/>
<label for="input"></label>
