模态位置误差

Question

我是CSS的初学者。我正在编辑一个模态窗口，但我在位置上有问题。这个模式窗口，每当我改变浏览器的分辨率，它就有一个定位问题，显示在屏幕截图中。我需要宽度和高度大小以%表示。

屏幕截图

模态HTML：

<div class="modal fade" id="erroAdocaoAindaNaoConcluida" tabindex="-1" role="dialog" aria-labelledby="erroAdocaoAindaNaoConcluidaLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header" align="center">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>

                <span class="titulo_modal" id="erroAdocaoAindaNaoConcluidaLabel">Detectamos um erro</span>

            </div>

            <div class="modal-body" align="center">
                <p class="titulo_form"> Você só pode adotar um animal por vez.</p>
            </div>

            <div class="modal-footer">

                <button type="button" class="tamanho_btn_adotar btn-primary" data-dismiss="modal">Fechar</button>

            </div>
        </div>
    </div>
</div>

情态-内容CSS：

.modal-content{
   position:relative;width:45%; 
   background-color:#fff;
   -webkit-background-clip:padding-box;
   background-clip:padding-box;
   border:1px solid #999;
   border:1px solid rgba(0,0,0,.2);
   border-radius:6px;
   outline:0;
   -webkit-box-shadow:0 3px 9px rgba(0,0,0,.5);
   box-shadow:0 3px 9px rgba(0,0,0,.5)
}

.modal-content{
   -webkit-box-shadow:0 5px 15px rgba(0,0,0,.5);
   box-shadow:0 5px 15px rgba(0,0,0,.5)
}

模态-正文CSS：

.modal-body{position:relative;padding:15px}

模态-对话框CSS：

.modal-dialog{width:600px;margin:30px auto}
.modal-dialog{
   -webkit-transform:translate(0,0);
   -ms-transform:translate(0,0);
   -o-transform:translate(0,0);
   transform:translate(0,0)
 }

.modal-dialog{
   position:relative;
   width:auto; 
   top:20px; 
   left:8%;
   margin:10px
}

我已经删除了css中的一些内容，并添加了额外的元素，只需尝试下面的代码片段

	background-color: #fff;
	-webkit-background-clip: padding-box;
	background-clip: padding-box;
	border: 1px solid #999;
	border: 1px solid rgba(0,0,0,.2);
	border-radius: 6px;

	-webkit-box-shadow: 0 3px 9px rgba(0,0,0,.5);
	box-shadow: 0 3px 9px rgba(0,0,0,.5);
	margin: 0 auto;
}
.modal-content {
	-webkit-box-shadow: 0 5px 15px rgba(0,0,0,.5);
	box-shadow: 0 5px 15px rgba(0,0,0,.5)
}
.modal-dialog {

}
.modal-dialog {
	-webkit-transform: translate(0, 0);
	-ms-transform: translate(0, 0);
	-o-transform: translate(0, 0);
	transform: translate(0, 0)
}

	width: auto;
	top: 20px;
	margin: 10px
}
.modal-body {
	position: relative;
	padding: 15px

}
}
