CSS 3選擇器：具有類名的第一類型？是否可以使用CSS 3選擇器？:first-of-type選擇具有給定類名的第一個元素？我的測試還沒成功，所以我想不是？守則(http://jsfiddle.net/YWY4L/):p:first-of-type {color:blue}p.myclass1:first-of-type {color:red}.myclass2:first-of-type {color:green}<div>  <div>This text should appear as normal</div>  <p>This text should be blue.</p>  <p class="myclass1">This text should appear red.</p>  <p class="myclass2">This text should appear green.</p></div>
