Question

嗨伙计们，我正在努力实现这一目标:(我希望按钮和数量框在同一条线上）

但由于某种原因，我的按钮低于我的量化盒，我不知道为什么，我现在正在使用bootstrap 3我试图使用col 6每个并尝试display inline但不知道如何使其工作

HTML：

.plus-minus-input {
    	display: -webkit-box;
    	display: -ms-flexbox;
    	display: flex;
    	-webkit-align-items: center;
    	-ms-flex-align: center;
    	align-items: center;
    	margin-left: 136px;
    }
    .plus-minus-input .input-group-field {
    	text-align: center;
    	width: 50px;
    	height: 41px;
    	font-size: 16px;
    	line-height: 1.2;
    	border: 2px solid #e6e6e6;
    }
    .plus-minus-input .input-group-field::-webkit-inner-spin-button, .plus-minus-input .input-group-field ::-webkit-outer-spin-button {
    	-webkit-appearance: none;
    	appearance: none;
    }
    .plus-minus-input .input-group-button .circle1 {
    	border-top-left-radius: 3px;
    	border-bottom-left-radius: 3px;
    }
    .plus-minus-input .input-group-button .circle2 {
    	border-top-right-radius: 3px;
    	border-bottom-right-radius: 3px;
    }
    .btn-primary {
    	border-radius: 0px;
    	width: 42px;
    	height: 41px;
    	background-color: #e6e6e6;
    	border: 2px solid #e6e6e6;

							</div>
						</div>
						<button class="btn btn-danger" type="button">Add to cart</button>
    

任何帮助都会很棒，谢谢

在display: inline-flex;类中使用.plus-minus-input，我还在按钮标记中为css添加了addcart类，如：

.addcart {
    display: inline-block;
    width: auto;
}

.plus-minus-input {
    display: -webkit-box;
    display: -ms-flexbox;
    display: inline-flex;
    -webkit-align-items: center;
    -ms-flex-align: center;
    align-items: center;
    margin-left: 136px;
}
.plus-minus-input .input-group-field {
    text-align: center;
    width: 50px;
    height: 41px;
    font-size: 16px;
    line-height: 1.2;
    border: 2px solid #e6e6e6;
}
.plus-minus-input .input-group-field::-webkit-inner-spin-button, .plus-minus-input .input-group-field ::-webkit-outer-spin-button {
    -webkit-appearance: none;
    appearance: none;
}
.plus-minus-input .input-group-button .circle1 {
    border-top-left-radius: 3px;
    border-bottom-left-radius: 3px;
}
.plus-minus-input .input-group-button .circle2 {
    border-top-right-radius: 3px;
    border-bottom-right-radius: 3px;
}
.btn-primary {
    border-radius: 0px;
    width: 42px;
    height: 41px;
    background-color: #e6e6e6;
    border: 2px solid #e6e6e6;
    color: #888888;
}
.btn-primary:hover, .btn-primary:active:focus, .btn:focus, .btn:active, .btn-primary:focus {
    color: #888888;
    background-color: #e6e6e6;
    border-color: #e6e6e6;
    outline: none !important;
    box-shadow: none;
}
.btn-danger {
    background-color: #222222;
    border-radius: 23px;
    font-family: Montserrat-Regular;
    font-size: 15px;
    color: white;
    text-transform: uppercase;
    border-color: #222222;
    width: 57%;
    height: 100%;
    padding: 9px;
    margin-bottom: 50px;
}
.btn-danger:hover {
    background-color: #c39d6d;
    border-color: #c39d6d;
}
.addcart {
    display: inline-block;
    width: auto;
}
