不可能。在HTML中，您不能將圖像放入''標籤。你仍然可以嘗試用一些CSS作弊。 – <span class="text-secondary"> <small> <span></span> </small> </span> </p> </div> </div> </div> <div itemprop="comment" class="post-comment"> <div class="row"> <div class="col-lg-1"><span class="text-secondary">+0</span></div> <div class="col-lg-11"> <p class="commenttext">你想要在中心的角落裏的圖標......？你想與該圖標互動，點擊...？ – <span class="text-secondary"> <small> <span></span> </small> </span> </p> </div> </div> </div> <div itemprop="comment" class="post-comment"> <div class="row"> <div class="col-lg-1"><span class="text-secondary">+0</span></div> <div class="col-lg-11"> <p class="commenttext">您總是可以製作一個由TextArea和Button組成的自定義小部件，其中一些角落上浮動着圖像。 – <span class="text-secondary"> <small> <a rel="noopener" target="_blank"
