Question

我制作了一个按钮CSS，我需要在悬停时看到内容。

内容放在带有class =“a-btn-slide-text”的范围内。但是我无法增加范围的宽度。如何在不妨碍其他css类的情况下增加大小？

div class="content">
                <div class="button-wrapper">
                    <a href="#" class="a-btn">
                        <span class="a-btn-text">New Appraisal Type</span> 
                        <span class="a-btn-slide-text">
                            <input type="radio"/>Single Upload
                            <input type="radio"/>Bulk Upload
                        </span>

                        <span class="a-btn-icon-right"><span></span></span>
                    </a>
                </div>
        </div>

Answer 1

Span是一个内联元素。它没有宽度或高度。

因此，如果要设置高度或宽度，则必须设置display: block;
如Stefan所说，它会像div一样呈现它。

Answer 2

使用display:inline-block;。内联元素通常不能指定宽度。

.a-btn-slide-text {display:inline-block;width:...}

如果您使用display:block;'，则会将span呈现为div。

对于inline，block和inline-block，go here之间的差异。

Answer 3

我想我得到了你想要达到的目标。这是一个小提琴：

我刚刚在这里添加了一个Padding并将宽度设置为200px：

.a-btn:hover .a-btn-text{
    padding-right:200px;
    text-shadow:0px 1px 1px #5d81ab;
    color:#fff;
}
.a-btn:hover .a-btn-slide-text{
    width:200px;
}
