如何使用CSS在三角形div上书写？

I'm currently trying to write words over a triangle-shaped div that I created using CSS.

我正在尝试在我使用CSS创建的三角形div上写单词。

Here:

.triangle-topright {
  width: 0;
  height: 0;
  border-top: 100px solid gray;
  border-left: 100px solid transparent;
}

<div class="triangle-topright">view</div>

As you can see, view is misplaced as I want it to be inside the shape. I also want it to rotate so It's nice for the eye. I know that text rotation goes something like this (example):

正如您所看到的,视图是错误的,因为我希望它在形状内部。我也希望它旋转所以这对眼睛很好。我知道文本轮换就像这样(例子):

-moz-transform: rotate(-90deg);

Can I achieve the goal using CSS or do I need to add some JS?

我可以使用CSS实现目标还是需要添加一些JS?

Thanks a lot!

非常感谢!

Some of the answers above achieve the same already. Here is my JSfiddle you can play around with.

上面的一些答案已经达到了同样的效果。这是我可以玩的JSfiddle。

http://jsfiddle.net/tmtg1oc8/

.container {
    position: relative;
}

.triangle {
    position: absolute;
    top: 0;
    left: 0;
    width: 0;
    height: 0;
    border-top: 100px solid gray;
    border-left: 100px solid transparent;
    z-index: -1;
}

.content {
    padding: 40px;
}

And the html

和HTML

<div class="container">
    <div class="triangle"></div>
    <div class="content">hello</div>
</div>

Here's an example of doing it with just CSS.

这是一个用CSS做的例子。

HTML

<section class="page_block">
    <div class="row">
        <div class="col-md-1">
            <div id="header">
                <h1 class="verticaltext">
                    Vert Text
                </h1>
            </div>
        </div>
        <div class="col-md-11">
            <p>Column Somethin?</p>
        </div>
    </div>
</section>

CSS

.page_block {
    margin:0px;
    padding:10px;
}
#header { 
    position: relative; 
}
.verticaltext {
    transform: rotate(45deg);
    transform-origin: right, top;
    -ms-transform: rotate(45deg);
    -ms-transform-origin:right, top;
    -webkit-transform: rotate(45deg);
    -webkit-transform-origin:right, top;
    position: absolute; 
    color: #ed217c;
}
