按钮后面的水平线 HTML/CSS

Question

我正在重新制作学校的学生 Intranet 以进行评估，但我遇到了按钮问题。正如您在图片中看到的，在按钮链接之间的间隙中可以看到一条水平线。

发生这种情况有什么原因吗？如果有帮助，我已经附上了网站按钮部分的 CSS 和 HTML 代码。

CSS：

.button {
    background-color:rgba(255, 255, 255, 0.5);
    border:none;
    width:auto;
    height:auto;
    border-radius:3px;
    color:#ffffff;
    font-size:16px;
    cursor:pointer;
    padding:15px;
    z-index:3;
}

.button:hover {
    color:#000000;
    transition:.2s;
    background-color:rgba(255, 255, 255, 0.8);
    padding-left:18px;
    padding-right:18px;
}

.button:active {
    color:#000000;
}

.button:focus {
    outline-color:gold;
}

HTML：

<div class="links">

    <h2>Links</h2>

        </a>



    </div>

感谢任何帮助。谢谢！

Answer 1

该行是按钮代码中<a> 标记的延续。将他们的 display 属性从 inline（默认）更改为 inline-block 应该可以解决问题。

.links a {
  display: inline-block;
}

Answer 2

将<a>标签移动到<button>标签内

    <div class="links">

    <h2>Links</h2>

    <button class="button">
        <a href="http://jhclibrary.weebly.com/" alt="JHC Library Website">
        Library Website
        </a>
    </button>

    <button class="button">
        <a href="http://jhclibrary.weebly.com/research.html" alt="Research">                    Research
        </a>
    </button>

    <button class="button">
        <a href="http://jameshargestcollege.wheelers.co/" alt="eBooks">
                eBooks
        </a>
    </button>

    <button class="button">
        <a href="10.0.0.7" alt="Library Catalogue">
                Library Catalogue
                </a>
    </button>

    <button class="button"> <a href="http://studentintranet/Documents/SubjectBooklets/ElLink.html" alt="Subject Booklets">

                Subject Booklets

        </a>
    </button>

    <button class="button">
        <a href="http://studentintranet/Documents/Options/ElLink.html" alt="Option Books">Option Books
