我有一些基本的按钮样式,在：hover上我添加了letter-spacing属性：
.btn {
display: inline-block;
text-align: center;
background-color: transparent;
border: 1px solid transparent;
padding: 0.375rem 0.75rem;
font-size: 1rem;
border-radius: 0.25rem;
cursor: pointer;
transition: all 0.2s ease;
}
.btn-primary {
background-color: #8065F1;
color: #FFFFFF;
}
.btn-large {
border-radius: 32px;
Box-shadow: 0 2px 80px 0 rgba(74,74,0.23);
padding: 0.25rem 3rem;
font-size: 1.5rem;
text-transform: uppercase;
}
.btn:hover {
letter-spacing: 4px;
}<button type="button" class="btn btn-primary btn-large">Lorem</button>有没有办法不扩大宽度？喜欢添加最小/最大宽度吗？但是,问题在于按钮元素可以包含不同的字符串长度：
.btn {
display: inline-block;
text-align: center;
background-color: transparent;
border: 1px solid transparent;
padding: 0.375rem 0.75rem;
Box-shadow: 0 2px 80px 0 rgba($grey,0.23);
font-size: 1rem;
border-radius: 0.25rem;
cursor: pointer;
transition: all 0.2s ease;
}
.btn-primary {
background-color: #8065F1;
color: #FFFFFF;
}
.btn-large {
border-radius: 32px;
-webkit-Box-shadow: 0 2px 80px 0 rgba(74,0.23);
Box-shadow: 0 2px 80px 0 rgba(74,0.23);
padding: 0.25rem 3rem;
font-size: 1.5rem;
text-transform: uppercase;
min-width: 240px;
}
.btn:hover {
letter-spacing: 4px;
}<p>I need this "effect" (I added some min-width):</p>
<button type="button" class="btn btn-primary btn-large">Lorem</button>
<p>However it won't work for larger strings</p>
<button type="button" class="btn btn-primary btn-large">Lorem Ipsum</button><br><br>
<button type="button" class="btn btn-primary btn-large">Lorem Ipsum Dolor</button>我知道我可以使用JS并将元素固定宽度附加到它上面,但是我正在寻找一种CSS解决方案-如果有的话？
最佳答案
大概的想法是,复制文本时要考虑一个隐藏的文本,该文本已经具有字母间距,而另一个文本在动画顶部以填充该隐藏文本已经定义的空间：
原文链接：https://www.f2er.com/css/530688.html这是通过使文本颜色与背景颜色相同来实现的：
.btn {
display: inline-block;
text-align: center;
background-color: transparent;
border: 1px solid transparent;
padding: 0.375rem 0.75rem;
font-size: 1rem;
border-radius: 0.25rem;
cursor: pointer;
transition: all 0.2s ease;
margin-bottom:10px;
}
.btn-primary {
background-color: #8065F1;
color: #FFFFFF;
}
.btn-large {
border-radius: 32px;
Box-shadow: 0 2px 80px 0 rgba(74,0.23);
padding: 0.25rem 3rem;
font-size: 1.5rem;
text-transform: uppercase;
}
.btn::before {
content:attr(data-text);
position:absolute;
left:0;
right:0;
text-align:center;
letter-spacing: initial;
color:#fff;
transition: all 0.2s ease;
}
.btn {
letter-spacing: 4px;
color:#8065F1;
position:relative;
}
.btn:hover::before {
letter-spacing: 4px;
}<div><button type="button" class="btn btn-primary btn-large" data-text="Lorem">Lorem</button></div>
<div><button type="button" class="btn btn-primary btn-large" data-text="Lorem Ipsum">Lorem Ipsum</button></div>
<div><button type="button" class="btn btn-primary btn-large" data-text="Lorem Ipsum Dolor">Lorem Ipsum Dolor</button></div>如果背景不是纯色,则另一个使用不透明度和两个伪元素：
.btn {
display: inline-block;
text-align: center;
background-color: transparent;
border: 1px solid transparent;
padding: 0.375rem 0.75rem;
font-size: 1rem;
border-radius: 0.25rem;
cursor: pointer;
transition: all 0.2s ease;
margin-bottom:10px;
}
.btn-primary {
background: linear-gradient(#8065F1,purple);
color: #FFFFFF;
}
.btn-large {
border-radius: 32px;
Box-shadow: 0 2px 80px 0 rgba(74,0.23);
padding: 0.25rem 3rem;
font-size: 1.5rem;
text-transform: uppercase;
}
.btn {
position:relative;
font-size:0;
}
.btn::before {
content:attr(data-text);
position:absolute;
left:0;
right:0;
text-align:center;
letter-spacing: initial;
font-size: 1.5rem;
transition: all 0.2s ease;
}
.btn::after {
content:attr(data-text);
letter-spacing: 4px;
opacity:0;
font-size: 1.5rem;
}
.btn:hover::before {
letter-spacing: 4px;
}<div><button type="button" class="btn btn-primary btn-large" data-text="Lorem">Lorem</button></div>
<div><button type="button" class="btn btn-primary btn-large" data-text="Lorem Ipsum">Lorem Ipsum</button></div>
<div><button type="button" class="btn btn-primary btn-large" data-text="Lorem Ipsum Dolor">Lorem Ipsum Dolor</button></div>
