Penjajaran bawah css Taildwind

Question

Hai, saya baru cuba menghantar ke bahagian bawah induknya:

<form class="flex flex-col w-full" (submit)="updatePhoto(title, description)">
        <div class="w-full block">
            <input type="text" class="shadow appearance-none border rounded w-full py-2 px-3 text-gray-700 leading-tight focus:outline-none focus:shadow-outline" placeholder="Photo's Title" [value]="photo.title" #title>
        </div>
        <div class="my-4 w-full">
            <textarea rows="2" class="shadow appearance-none border rounded w-full py-2 px-3 text-gray-700 leading-tight focus:outline-none focus:shadow-outline resize-none" placeholder="Photo's Description" [value]="photo.description" #description></textarea>
        </div>
        <div class="grid justify-items-end  mt-auto  border ">
            <div>
                <button class="text-white bg-gradient-to-r from-red-400 via-red-500 to-red-600 hover:bg-gradient-to-br focus:ring-4 focus:outline-none focus:ring-red-300 dark:focus:ring-red-800 shadow-lg shadow-red-500/50 dark:shadow-lg dark:shadow-red-800/80 font-medium rounded-lg text-sm px-5 py-2.5 text-center mr-2 mb-2" (click)="deletePhoto(photo._id)">
                    Delete
                </button>
                <button class="text-white bg-gradient-to-r from-blue-500 via-blue-600 to-blue-700 hover:bg-gradient-to-br focus:ring-4 focus:outline-none focus:ring-blue-300 dark:focus:ring-blue-800 shadow-lg shadow-blue-500/50 dark:shadow-lg dark:shadow-blue-800/80 font-medium rounded-lg text-sm px-5 py-2.5 text-center mr-2 mb-2 ">
                    Update
                </button>
            </div>
        </div>
 </form>

Jadi saya ingin menyelaraskan elemen (butang) ke bahagian bawah induknya, saya menggunakan flex flex-col 我正在使用 grid justify-items-end mt-auto 但不起作用，所以我只是添加了 border pada ibu bapa dan anak untuk melihat kedudukan dan saya mendapat ini:

Anda boleh melihat butang telah muncul, apa yang salah? Kenapa

Answer 1

Hanya gunakan grid pada bekas luar dan ia akan berfungsi dengan baik. Terdapat juga banyak peluang untuk memudahkan markup dan kelas.
