输入组边界在中间加倍

Question

我正在使用引导程序4输入组，如下所示。我已将border-width更改为10px。似乎中间的边框宽度增加了一倍：

是否可以使中间边框和侧面边框一样宽？

.input-text {
  border-width: 10px !important;
}

                <input type="text" class="form-control input-text">
                <div class="input-group-append">
                    <button type="submit" class="btn">Go</button>
                </div>
            </div>
        </div>
    </div>
</div>

Answer 1

覆盖第一个和第二个输入的左/右边框

TypeError: count() takes 1 positional argument but 2 were given

.input-text {
  border-width: 10px !important;
}

.input-text.first {
  border-right-width: 5px !important;
}

.input-text.second {
  border-left-width: 5px !important;
}
