html - float :right element not inline with float:left element

Question

我有一个以旋转方式显示的标题 #resourceWrapTitle。我用于定位的一方面是 float:left。当我这样做时，它使我的容器在右边的位置显示在我想要的位置的顶部稍微向下 - container #resourceCont。我将此容器设置为 float:right，所以我认为它会出现在标题旁边。

有谁知道为什么 #resourceCont 被下推，我该如何解决？

我想要容器的地方的图片:

#pdfBannerRight {
	width: 300px;
	background: #2f2f2f;
	height: 450px;
	position: absolute;
	top: 18%;
	right: 0;
}
#pdfBannerRightCont {
	position: relative;
	width: 100%;
	height: 100%;
}
#resourceWrapTitle {
	float: left;
    transform-origin: top left;
	margin: 3% 0 0 8px;
    -webkit-transform: rotate(-90deg) translateX(-100%);
    transform: rotate(-90deg) translateX(-100%);
    font-family: 'Nunito', sans-serif;
    letter-spacing: .2rem;
    font-size: 1.7rem;
    color: #FFF;
    text-transform: uppercase;

}
#resourceWrapTitle:after {
	content: '';
	display: block;
	height: 4px;
	background: #FFF;
	width: 80%;
	text-align: center;
	margin: 10px auto;
}
#pdfResourceWrap {
	float: right;
	margin: 0 auto;
	padding: 20px 0;
	width: 80%;
	height: auto;
}
.pdfResource {
	width: 48%;
	height: auto;
	display: inline-block;
	vertical-align: top;
	margin: 15px 1%;
	padding: 5px 0;
	text-align: center;

.pdfResource:hover {
	background: gray;

}
.pdfResource img {
	width: 50px;
	height: auto;
	margin: 0 auto;
}
.resourceTitle {

	letter-spacing: .1rem;
	color: #F2F2F2;
	margin-top: 5px;
	line-height: 1.4em;
	padding: 0 5px;
}

Answer 1

我所做的更改:

来自

#resourceWrapTitle {
    float: left;
}

至

#resourceWrapTitle {
    position: absolute;
    top: 0;
    left: 0;
}

#pdfResourceWrap 没有将自己置于顶部的原因是，#resourceWrapTitle 仍然位于顶部。它已旋转但仍处于文档流中，保持其原始位置。但是当我从中删除 float 并给它一个 absolute 位置时，它不在文档流中，因此不在原来的位置。阅读 css box model和 css position如果你还不清楚。

希望对您有所帮助。谢谢。
