背景
使用Bootstrap Modal实现用户资料修改，由于用户信息过多，默认Modal出现页面滚动条，为了用户体验，不使用页面滚动条，在Modal body部分加垂直滚动条，Modal header和footer固定位置。
效果
代码
加入CSS样式
.modal-dialog { position: absolute; top: 0; bottom: 0; left: 0; right: 0; } .modal-content { /*overflow-y: scroll; */ position: absolute; top: 0; bottom: 0; width: 100%; } .modal-body { overflow-y: scroll; position: absolute; top: 55px; bottom: 65px; width: 100%; } .modal-header .close {margin-right: 15px;} .modal-footer { position: absolute; width: 100%; bottom: 0; }- 1
