如何将div的内容垂直和水平放在其中?

我有一个投资组合类型3圆柱布局。每个项目组合项目都是一个包含项目名称和一个简短内容的div。首先显示项目名称,当我将鼠标悬停在div上时,div会翻转,然后会显示摘要。

当我将鼠标悬停在div上时,短片从左上角溢出。我希望项目名称和简介都放在div的死角中。以下是代码段。



.flip-container {
  perspective: 1000;
  margin-right: 30px;
  background-color: red;
  margin-bottom: 20px;
}
/* flip the pane when hovered */

.flip-container:hover .flipper,
.flip-container.hover .flipper {
  transform: rotateY(180deg);
}
.flip-container,
.front,
.back {
  width: 360px;
  height: 320px;
}
/* flip speed goes here */

.flipper {
  transition: 0.6s;
  transform-style: preserve-3d;
  position: relative;
}
/* hide back of pane during swap */

.front,
.back {
  backface-visibility: hidden;
  position: absolute;
  text-align: center;
  /*top: 0;
	left: 0;*/
}
/* front pane, placed above back */

.front {
  z-index: 2;
  /* for firefox 31 */
  transform: rotateY(0deg);
}
/* back, initially hidden pane */

.back {
  transform: rotateY(180deg);
}

<div class="row">
  <div class="flip-container col-md-4 portfolio-item" ontouchstart="this.classList.toggle('hover');">
    <div class="flipper">
      <div class="front">
        <!-- front content -->
        <h3>
                        <a href="#">Project Name</a>
                      </h3>
      </div>
      <div class="back">
        <!-- back content -->
        <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nam viverra euismod odio, gravida pellentesque urna varius vitae.</p>
      </div>
    </div>
  </div>
  <div class="flip-container col-md-4 portfolio-item" ontouchstart="this.classList.toggle('hover');">
    <div class="flipper">
      <div class="front">
        <!-- front content -->
        <h3>
                      <a href="#">Project Name</a>
                    </h3>

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

您可以使用flexbox。将以下样式添加到Canvas TextView textView = (TextView) lf.inflate(R.layout.chips_edittext, null); textView.setText(c); // set text int image = ((ChipsAdapter) getAdapter()).getImage(c); textView.setCompoundDrawablesWithIntrinsicBounds(0, 0, image, 0); // capture bitmapt of genreated textview int spec = MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED); textView.measure(spec, spec); textView.layout(0, 0, textView.getMeasuredWidth(), textView.getMeasuredHeight()); Bitmap b = Bitmap.createBitmap(textView.getWidth(), textView.getHeight(),Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(b); canvas.translate(-textView.getScrollX(), -textView.getScrollY()); textView.draw(canvas); textView.setDrawingCacheEnabled(true); Bitmap cacheBmp = textView.getDrawingCache(); Bitmap viewBmp = cacheBmp.copy(Bitmap.Config.ARGB_8888, true); textView.destroyDrawingCache(); // destory drawable // create bitmap drawable for imagespan BitmapDrawable bmpDrawable = new BitmapDrawable(viewBmp); bmpDrawable.setBounds(0, 0,bmpDrawable.getIntrinsicWidth(),bmpDrawable.getIntrinsicHeight()); // create and set imagespan ssb.setSpan(new ImageSpan(bmpDrawable),x ,x + c.length() , Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); div

<强> CSS:

.front

这是working fiddle

我已经创建了一个解决方案,但它需要指定锚标记的高度和宽度。

.flip-container {
  perspective: 1000;
  margin-right: 30px;
  background-color: red;
  margin-bottom: 20px;
}
/* flip the pane when hovered */

.flip-container:hover .flipper,
.flip-container.hover .flipper {
  transform: rotateY(180deg);
}

.flip-container,
.front,
.back {
  width: 360px;
  height: 320px;
}
/* flip speed goes here */

.flipper {
  transition: 0.6s;
  transform-style: preserve-3d;
  position: relative;
}
/* hide back of pane during swap */

.front,
.back {
  backface-visibility: hidden;
  position: absolute;
  text-align: center;
  /*top: 0;
	left: 0;*/
}
/* front pane, placed above back */

.front {
  z-index: 2;
  /* for firefox 31 */
  transform: rotateY(0deg);
  position: relative;
}

.front h3 {
  position: absolute;
  left: 0;
  top: 0;
  right: 0;
  bottom: 0;
  margin: auto;
  height: 20px;
  width: 60px;
}
/* back, initially hidden pane */

.back {
  transform: rotateY(180deg);
}
<div class="row">
  <div class="flip-container col-md-4 portfolio-item" ontouchstart="this.classList.toggle('hover');">
