我的容器內(nèi)有一個(gè)輸入和一個(gè)文本區(qū)域，該容器的height: 52.5vh. 我希望文本區(qū)域從輸入的正下方開始并擴(kuò)展到容器的末尾。我怎樣才能這樣做呢？順便說一句，這兩個(gè)元素都應(yīng)該填充整個(gè)寬度。.contact__user-input { max-height: 52.5vh; height: 52.5vh; overflow: scroll; background-color: yellow;}textarea { background-color: lightgray; border: 1px solid grey; outline: none; color: black; letter-spacing: 0; text-transform: none; box-shadow: none; resize: none; padding: 0.7rem;}<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" rel="stylesheet"/><div class="contact__user-input d-flex"> <input type="text" class="form-control" placeholder="Input"/> <textarea class="contact__textarea separator--small h-100 w-100" placeholder="Textarea"></textarea></div>

您可以flex為父母使用并使其column明智。
.contact__user-input {
max-height: 52.5vh;
height: 52.5vh;
overflow: scroll;
background-color: yellow;
display:flex;
flex-direction:column;
}
textarea {
background-color: lightgray;
border: 1px solid grey;
outline: none;
color: black;
letter-spacing: 0;
text-transform: none;
box-shadow: none;
resize: none;
padding: 0.7rem;
height:auto;
}

為下面的 div 添加了 flex-wrap 類，并更正了 bootstrap cdn url。請(qǐng)檢查片段。
<div class="contact__user-input d-flex flex-wrap">
.contact__user-input {
max-height: 52.5vh;
height: 52.5vh;
overflow: scroll;
background-color: yellow;
}
textarea {
background-color: lightgray;
border: 1px solid grey;
outline: none;
color: black;
letter-spacing: 0;
text-transform: none;
box-shadow: none;
resize: none;
padding: 0.7rem;
}
