                                                        </div>
                                                        <div style="clear:both;"></div>
                                                </div>
                                            </div>
                                        </div>
                            </form>
                </div>
            </div>

正如评论中已经提到的,您应该使用 JavaScript 来验证表单。这是一个可运行的代码片段:

function formValidate() {
  var fname = document.getElementById("fname").value;
  var lname = document.getElementById("lname").value;
  var email = document.getElementById("email").value;
  var tc = document.getElementById("tc");
  if (fname.length === 0) {
    document.getElementById("errfname").style.display = "block";
    document.getElementById("errorbox").style.display = "block";
  } else {
    document.getElementById("errfname").style.display = "none";
  }
  if (lname.length === 0) {
    document.getElementById("errlname").style.display = "block";
    document.getElementById("errorbox").style.display = "block";
  } else {
    document.getElementById("errlname").style.display = "none";
  }
  if (email.length === 0) {
    document.getElementById("erremail").style.display = "block";
    document.getElementById("errorbox").style.display = "block";
  } else {
    document.getElementById("erremail").style.display = "none";
  }
  if (tc.checked === false) {
    document.getElementById("errtandc").style.display = "block";
    document.getElementById("errorbox").style.display = "block";
  } else {
    document.getElementById("errtandc").style.display = "none";
  }
  if (fname.length !== 0 && lname.length !== 0 && email.length !== 0 && tc.checked === true) {
    window.location.href = "https://whosebug.com";
  }
}
body {
  background-color: lightblue;
}

input[type=text],
input[type=email] {
  width: 80%;
  font-size: 20px;
  float: right;
}

.errorbox {
  background-color: red;
  color: white;
  width: 98%;
  position: relative;
  padding: 1%;
  display: none;
}
