你好，我想在
我用來居中的表格中居中影像position: absolute，但沒有用
position: absolute;
left: 50%;
top: 50%;
像這樣：
到目前為止，我已經嘗試過這段代碼：
body {
top: 0;
padding: 0;
left: 0;
margin: 0;
height: 100vh;
width: 100%;
font-family: Arial;
position: relative;
background: linear-gradient(48deg, #1f3347 50%, #2c4050 50%);
}
.from_body {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
height: 390px;
width: 400px;
border-radius: 10px;
border-top-left-radius: 50%;
border-bottom-right-radius: 50%;
border: 1px solid #2980b9;
}
.from_body img {
height: 120px;
width: 120px;
position: absolute;
left: 33%;
margin-top: -67px;
}
.from_body .text {
font-size: 30px;
font-weight: 600;
color: white;
margin-left: 120px;
margin-top: -5px;
border-bottom: 2px solid;
border-radius: 3px;
width: 160px;
}<body>
<div class="form_body">
<img

<p class="text">User login</p>
</div>
</body>我是初學者，我將不勝感激！
uj5u.com熱心網友回復：
OP 中的 PNG 看起來并不透明，所以我得到了一個透明的。body 有 flexbox 屬性，<div>s 被替換為 a<figure>和<figcaption>語意。將<img>符合<figure>由于的尺寸object-fit: contain。
body {
display: flex;
flex-flow: column nowrap;
justify-content: center;
align-items: center;
min-height: 100%;
width: 100%;
font: 3ch/1 'Segoe UI';
background: linear-gradient(48deg, #1f3347 50%, #2c4050 50%);
}
figure {
width: max-content;
margin: 0 auto;
}
figcaption {
text-align: center;
color: #fff
}
img {
object-fit: contain;
}<body>
<figure>
<img src="https://9to5google.com/wp-content/uploads/sites/4/2017/05/google-contacts.png">
<figcaption>User Login</figcaption>
</figure>
