链接到另一个页面的问题

Question

我无法将某些文字（我想要链接的文字在h6中）与我创建的另一个页面相关联。我遵循标准格式但不知何故它不起作用。请帮帮我！

HTML代码：

    <ul class="ei-slider-large">
                    <li>
                        <img src="images/large/1.jpg" alt="slider1"/>
                        <div class="ei-title">
                            <h2>Welcome</h2> <br>
                            <h3>Child at Street 11</h3>
                        </div>
                    </li>
                    <li>
                        <img src="images/large/2.jpg" alt="slider2" />
                        <div class="ei-title2">
                            <h4>Enrol</h4><br>
                            <h5>Every child deserves to have an early education</h5><br>
                         <h6><a href="enrol.html">Enrol Now</a></h6> 
                        <br>

                        </div>
                    </li>
                    <li>
                        <img src="images/large/3.jpg" alt="slider3" />
                        <div class="ei-title2">
                            <h4>Donate</h4><br>
                            <h5>Give back to our society by helping the underpriviledged</h5><br>
                             <h6><a href="donate.html">Donate Now</a></h6>

                        </div>
                    </li>
                    <li>
                        <img src="images/large/4.jpg" alt="slider4"/>
                        <div class="ei-title2">
                            <h4>Volunteer</h4><br>
                            <h5>Lend us your hand with our many volunteer opportunities</h5><br>
                             <h6><a href="volunteer.html">Volunteer Now</a></h6>
                        </div>
                    </li>

                </ul>

CSS样式：

    .ei-title2 h6{
font-size: 25px;
text-decoration:underline;
font-family: 'Open Sans Condensed', sans-serif;
font-weight:300;
text-transform: uppercase;
color: #000;
letter-spacing:.02em;
background:#ffd40b;
display:inline;
padding: 0 10px 0 10px;}

    .ei-title2 h6 a:hover{
-webkit-text-stroke: 1px;}

谢谢亲切的灵魂！
