ホバリング時に画像にテキストを表示する方法は?

画像にカーソルを合わせると説明を表示しようとしています。ここでは、イメージスプライトとホバーを使用して、あまり望ましくない方法で既にそれを行っています: http://willryan.us/design.html 私のやり方ですが、画像の代わりに実際のテキストを使用しています。

私はいくつかの異なることを試しましたが、それを行う方法を理解できないようです。 HTMLとCSSのみを使用して実行しようとしていますが、それが可能かどうかはわかりません。

私のコードを自由に見て回ってください。ここに関連性があると思うものを貼り付けます。

HTML

div#projectlist {
  width: 770px;
  margin: 0 auto;
  margin-top: 20px;
  margin-bottom: 40px;
}

div#buzzbutton {
  display: block;
  float: left;
  margin: 2px;
  background: url(content/assets/thumbnails/design/buzz_Sprite.jpg) 0 0px no-repeat;
  width: 150px;
  height: 150px;
}

div#buzzbutton:hover {
  background: url(content/assets/thumbnails/design/buzz_Sprite.jpg);
  width: 150px;
  height: 150px;
  background-position: 0 -150px;
}

div#slinksterbutton {
  display: block;
  float: left;
  background: url(content/assets/thumbnails/design/slinkster_Sprite.jpg) 0 0px no-repeat;
  width: 150px;
  height: 150px;
  margin: 2px;
}

div#slinksterbutton:hover {
  background: url(content/assets/thumbnails/design/slinkster_Sprite.jpg);
  width: 150px;
  height: 150px;
  background-position: 0 -150px;
}
<div id="projectlist">
  <div id="buzzbutton">
    <a href="buzz.html" title=""><img src="content/assets/thumbnails/transparent_150x150.png" alt="" /></a>
  </div>

  <div id="slinksterbutton">
    <a href="slinkster.html" title=""><img src="content/assets/thumbnails/transparent_150x150.png" alt="" /></a>
  </div>
</div>

それは簡単です。画像を囲み、「ホバーに表示」の説明を同じ寸法のdivで囲みます。次に、CSSを使用して、そのdivの上にカーソルを置きながら説明を表示します。

/* quick reset */
* {
  margin: 0;
  padding: 0;
  border: 0;
}

/* relevant styles */
.img__wrap {
  position: relative;
  height: 200px;
  width: 257px;
}

.img__description {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  background: rgba(29, 106, 154, 0.72);
  color: #fff;
  visibility: hidden;
  opacity: 0;

  /* transition effect. not necessary */
  transition: opacity .2s, visibility .2s;
}

.img__wrap:hover .img__description {
  visibility: visible;
  opacity: 1;
}
<div class="img__wrap">
  <img class="img__img" src="http://placehold.it/257x200.jpg" />
  <p class="img__description">This image looks super neat.</p>
</div>

あなたのHTMLの中で、思いついたテキストをコードのタイトル部分に入れてみてください。

<a  href="buzz.html" title="buzz hover text">

あなたの画像の代替テキストについても同じことができます。

画像タグでtitle属性を使用することもできます

<img src="content/assets/thumbnails/transparent_150x150.png" alt="" title="hover text" />

これは、テキストをホバーに表示させるために使用するものです。

  height: 400px;
  position: absolute;
  border-radius: 50%
}

img:hover {
