html - 我的容器周围有白色边界线

Question

左右竖的白线是我不要的(不是横的，那些是hr)。我不知道是什么原因造成的。

那是我的 HTML。

@font-face {
    font-family: Futura;
    src: url(futura-medium.tff !important);
	color: #ffffff;
}

input[type="text"] { 
	color:white !important;
} 

input[type="email"] { 
	color:white !important;
} 

.model-content {
	color:black !important;
}

.text-left {
  text-align: left;
}

.text-right {
  text-align: right;
}

.text-center {
  text-align: center;
}

.navbar-default {
    background-color: #000000;
}

body {
	background: #f05324 !important; 
	margin-bottom: 80px;
	color: #ffffff;
}

.page-header, .panel-body, .panel, .panel-default, .col-lg-9, .row {
	background: #f05324 !important; 
}

.form-control{
    background-color: #f05324;
    color: #000000;
}

hr {
	border-color: #ffffff;
	background-color: #ffffff;
	color: #ffffff;
}

.link {
	color: #ffffff;
}

.page-header {
	margin-top: 0;
}

.panel-body {
	padding-top: 0;
}

.img-featured {
	margin-top   : 15px;
	margin-bottom: 15px;
	margin-right : 15px;
}

.img-project{
	margin-top   : 15px;
	margin-bottom: 15px;
}

.show-onclick {
	display: none;
}

.show-onclick1 {
	display: none;
}

.block {
    position: absolute;
    top: 0;
    bottom: 0;
    left: 50%;
    margin-left: // half the width of your img
}

这是我的 CSS。

知道是什么原因造成的吗？这很烦人。

Answer 1

它实际上来自 panel-default 类。尝试:

.panel-default {
    border: none;
}
