2018-06-01 11:01 更新

模態(tài)框（Modal）是覆蓋在父窗體上的子窗體。通常，使用模態(tài)框的目的是用來(lái)顯示來(lái)自一個(gè)單獨(dú)的源的內(nèi)容，而且可以在不離開父窗體的情況下有一些互動(dòng)。

模態(tài)框創(chuàng)建：

模態(tài)框尺寸

我們可以通過(guò)添加 .modal-sm 類來(lái)創(chuàng)建一個(gè)小模態(tài)框，.modal-lg 類可以創(chuàng)建一個(gè)大模態(tài)框。

尺寸類都放在 <div>元素的 .modal-dialog 類后 :
