ちょっと私はコードのようないくつかの変更を加えました。
HTMLコードで、ボタンを1つ追加しました-開始
<nav class="nav-bar">
<div class="nav-hold"> <a href="#" class="nav-logo">Qu<span id="blink">:</span>z Time - Guess this person</a>
<a href="#" class="nav-status" id="quiz_status"></a>
</div>
</nav>
<div class="wrap_container">
<div class="firstContainer">
<img id="question_image" src="" alt="" />
</div>
<div class="secondContainer">
<div class="answers"></div>
</div>
<div class="action">
<button id="answer">Answer</button>
<button id="start">Start</button>
<button id="clear">Clear</button>
</div>
</div>
cssで--
#start{
margin-left:50%;
}
スクリプトで--
$(document).ready(function () {
$("button#answer").css("display", "none");
$("button#clear").css("display","none");
//Global Variables
var questionNumber = 0,
