    模態(tài)框（Modal）是覆蓋在父窗體上的子窗體。通常，目的是顯示來自一個單獨的源的內(nèi)容，可以在不離開父窗體的情況下有一些互動。子窗體可提供信息交互等。
    


    如何創(chuàng)建模態(tài)框
    


    以下實例創(chuàng)建了一個簡單的模態(tài)框效果 ：

    使用 .fade 類可以設(shè)置模態(tài)框彈出或關(guān)閉的效果:

    模態(tài)框尺寸
    


    我們可以通過添加 .modal-sm 類來創(chuàng)建一個小模態(tài)框，.modal-lg 類可以創(chuàng)建一個大模態(tài)框。
    

    尺寸類放在 <div>元素的 .modal-dialog 類后 :

    全屏幕顯示
    


    使用 .modal-fullscreen 類可以讓模態(tài)框全屏幕顯示:

    模態(tài)框居中顯示
    

    使用 .modal-dialog-centered 類可以設(shè)置模態(tài)框水平和垂直方向都居中顯示:

    模態(tài)框滾動條
    默認情況下模態(tài)框如果包含很多內(nèi)容，頁面會自動生成一個滾動，模態(tài)框隨著頁面的滾動而滾動:
