html - 使用 CSS Grid 网格元素溢出父容器

我目前正在处理网格元素溢出父容器的问题。我不知道如何纠正这个问题。如果我调整视口(viewport)的大小，表单字段会溢出父容器，这并不理想。如果有人可以提供一些帮助，那就太好了。非常感谢!

这是下面列出的 HTML 结构:

这是下面列出的CSS代码:

body {

 }

 h1, h2 {
        margin-bottom: 5px;
    }

.framed-layout-part {
  border: none;
-webkit-box-shadow: 2px 2px 3px 0 #ccc;
-moz-box-shadow: 2px 2px 3px 0 #ccc;
box-shadow: 2px 2px 3px 0 #ccc;
position: relative;
border-radius: 3px;
border: none;
box-sizing: border-box;
background-color: #fff;
margin: 7px;
}

    .indent {
        margin-left: 15px;
    }

    .country-code-width {
        width: 20px !important;
    }

    .container {
        width: 30vw;
        margin: 30px auto;
    }

    .button-container {
        margin-top: 10px;
        display: flex;
        justify-content: flex-end;
    }

    #primary-email {
        border: none;
        background: lightgray;
    }

    @supports not (display: grid) {
        .person-edit-form-grid {
            display: flex;
            flex-direction: column;
        }

        .basic-info {
            margin: 15px 0;
        }

        .phone-info {
            width: 30vw;
        }

        .phone-info-grid {
            display: flex;
        }

        label {
            flex-basis: 80px;
        }

        .phone-info-grid > div {
            margin: 0 5px 5px 0;
        }
    }

    @supports (display: grid) {
        .person-edit-form-grid {
            display: grid;
            grid-row-gap: 20px;
            padding: 10px 0;
        }

        .basic-info {
            display: grid;
            grid-row-gap: 10px;
        }

        .basic-info-grid {
            display: grid;
            grid-template-columns: 100px max-content;
        }

        .phone-info {
            display: grid;
            grid-gap: 10px;
        }

        .phone-info-grid {
            display: grid;
            grid-template-columns: 100px repeat(3, max-content);
            grid-column-gap: 10px;
        }
    }

最佳答案

您可以使用媒体查询来减少较小视口(viewport)中的列数和列宽。例如:

@media screen and (max-width: 1350px){
  .phone-info-grid {
    grid-template-columns: 50px repeat(2, max-content);
  }
}

@media screen and (max-width: 900px){
  .phone-info-grid {
    grid-template-columns: 50px repeat(1, max-content);
  }
}
