Bootstrap 4 Font-awesome 輸入圖標

Question

我想弄清楚如何將字體很棒的圖標添加到我的輸入字段。 我找到了一個我非常喜歡的設計，我需要在輸入字段中放置圖標。 這是它的樣子：

但是我的表格看起來像這樣，我真的不知道如何添加它們。我尋找了很多答案，但沒有一個像往常一樣適合我，我希望我能在這里找到答案。

無論如何，這是表單的代碼。

您可以將position:absulote設置為 .fa 然后將position:relative添加到 .form-control

 form i.fa { position: absolute; top: 6px; left: 20px; color: blue; font-size: 22px; z-index: 9999; } .form-control { position: relative; padding-left: 45px !important; }
