Question

我是bootstrap的新手，我必须使用bootstrap制作一个形状为圆形的图像。当我为这个图像添加自己的CSS时，它变成了椭圆形。以下是html和css。

CSS：

.person {
            border: 10px solid transparent;
            margin-bottom: 25px;
            width: 80%;
            height: 80%;
            opacity: 0.7;
        }
        .person:hover {
            border-color: #f1f1f1;
        }

HTML：

<div class="row">
            <div class="col-sm-4">
                <p>
                    <strong>Test Member 1</strong>
                </p>
                <br />
                <a href="#demo" data-toggle="collapse">
                    <img src="images/bandmember.jpg" class="img-circle person" alt="Band Manager" />
                </a>
                <div id="demo" class="collapse">
                    <p>Guitarist and Lead Vocalist</p>
                    <p>Loves long walks on the beach</p>
                    <p>Member since 1988</p>
                </div>
            </div>
            <div class="col-sm-4">
                <p><strong>Test Member 2</strong></p><br />
                <a href="#demo2" data-toggle="collapse">
                    <img src="images/bandmember.jpg" class="img-circle person" alt="Random Name">
                </a>
                <div id="demo2" class="collapse">
                    <p>Guitarist and Lead Vocalist</p>
                    <p>Loves long walks on the beach</p>
                    <p>Member since 1988</p>
                </div>
            </div>
            <div class="col-sm-4">
                <p><strong>Test Member 3</strong></p><br />
                <a href="#demo3" data-toggle="collapse">
                    <img src="images/bandmember.jpg" class="img-circle person" alt="Random Name">
                </a>
                <div id="demo3" class="collapse">
                    <p>Guitarist and Lead Vocalist</p>
                    <p>Loves long walks on the beach</p>
                    <p>Member since 1988</p>
                </div>
            </div>
        </div>

Answer 1

这些风格：

width: 80%;
height: 80%;

...不要将宽度/高度设置为相对于当前大小。相反，他们设置相对于包含块的宽度/高度。因此，您几乎可以保证宽度和高度不匹配。

您需要使用％以外的其他尺寸单位。
