`:target` 使用模态实现

Question

我一直在寻找一种方法来做类似的事情：

（对于网页）使用HTML / CSS / jQuery，但无法做到。

我正在尝试制作一个按钮，当您将鼠标悬停在其上时，其他选项会显示出来。

Answer 1

以下是一个关于如何使用css和html创建浮动操作按钮（没有悬停效果）的示例

<button class="kc_fab_main_btn">+</button>

.kc_fab_main_btn{
  background-color:#F44336;
  width:60px;
  height:60px;
  border-radius:100%;
  background:#F44336;
  border:none;
  outline:none;
  color:#FFF;
  font-size:36px;
  box-shadow: 0 3px 6px rgba(0,0,0,0.16), 0 3px 6px rgba(0,0,0,0.23);
  transition:.3s;  
  -webkit-tap-highlight-color: rgba(0,0,0,0);
}
.kc_fab_main_btn:focus {
  transform:scale(1.1);
  transform:rotate(45deg);
  -ms-transform: rotate(45deg);
  -webkit-transform: rotate(45deg);
}

DEMO

这是一个简单的浮动动作按钮jQuery插件，以防你需要它。但是它在点击触发器上使用而不是悬停。

到目前为止，我已经找到了用于此目的的最佳教程：https://www.youtube.com/watch?v=iYFNaeEeCDI

有效的演示示例：https://verkkonet.com/downloads/demo.php?id=c9

HTML：

<div class="fab-container">
    <div class="fab fab-icon-holder">
        <i class="fas fa-question"></i>
    </div>
    <ul class="fab-options">
        <li>
            <span class="fab-label">Documentation</span>
            <div class="fab-icon-holder">
                <i class="fas fa-file-alt"></i>
            </div>
        </li>
        <li>
            <span class="fab-label">Video Tutorials</span>
            <div class="fab-icon-holder">
                <i class="fas fa-video"></i>
            </div>
        </li>
        <li>
            <span class="fab-label">Live Chat</span>
            <div class="fab-icon-holder">
                <i class="fas fa-comments"></i>
            </div>
        </li>
        <li>
            <span class="fab-label">Feedback</span>
            <div class="fab-icon-holder">

            </div>
        </li>
    </ul>
</div>

CSS：

.fab-container {
    position: fixed;
    bottom: 50px;
    right: 50px;
    z-index: 999;
    cursor: pointer;
}

.fab-icon-holder {

    border-radius: 100%;
    background: #016fb9;

    box-shadow: 0 6px 20px rgba(0, 0, 0, 0.2);
}

.fab-icon-holder:hover {
    opacity: 0.8;
}

.fab-icon-holder i {
    display: flex;
    align-items: center;
    justify-content: center;

    height: 100%;
    font-size: 25px;
    color: #ffffff;
}

.fab {
    width: 60px;
    height: 60px;
    background: #d23f31;
}

.fab-options {
    list-style-type: none;
    margin: 0;

    position: absolute;
    bottom: 70px;
    right: 0;

    opacity: 0;

    transition: all 0.3s ease;
    transform: scale(0);
    transform-origin: 85% bottom;
}

.fab:hover+.fab-options,
.fab-options:hover {
    opacity: 1;
    transform: scale(1);
}

.fab-options li {
    display: flex;
    justify-content: flex-end;
    padding: 5px;
}

.fab-label {
    padding: 2px 5px;

    margin-right: 10px;
}

这是我尝试悬停时的浮动按钮（HTML 和 CSS）的示例代码。

.flBtnCntr {
  display: inline-flex;
  position: absolute;
  top: 50px;
  left: 50px
}
.flBtnBox {
  outline: 0;
  border: 0;
  border-radius: 50%;
  background-color: #2978d3;
  color: #fff;
  cursor: pointer
}
.flBtnBox.big {
  background-color: #2978d3;
  font-size: 30px;
  height: 50px;
  width: 50px
}
.flBtnBox.small {
  animation: showBtn 150ms cubic-bezier(0.175, 0.885, 0.32, 1.275) forwards;
  transform: scale(0);
  background-color: #363636;
  margin: 0 5px;

@keyframes showBtn {

Answer 4

更新 5/3/2021

我今天重新审视了我的解决方案，并对我昨天未完成的那些部分添加了最后的润色。我还添加了一些额外的增强和风格改进。现在，对于 #mega-button 父级，它使用渐变背景，然后通过使用超大渐变和过渡 background-position 属性平滑过渡到褪色的蓝灰色背景颜色。当我旋转并增加子 .sub-button 元素的大小时，我还在悬停时减小此按钮的大小，以呈现从 .sub-button 后面滚出的 #mega-button 元素的外观。

为了让过渡感觉更平滑和自然，我还在每个 transition-delay 元素之间添加了一个轻微的 .sub-button 以创建瀑布效果，而不是它们都在彼此之上滚动。我在我的 SCSS 中使用 for 循环实现了这一点以及每个 .sub-button 的独特位置，并反向迭代 transition-delay 以使最右侧的按钮首先动画化。

当按钮从后面滚出时，我还使用了一些玻璃化样式，使 #mega-button 看起来像磨砂玻璃一样：backdrop-filter: blur(4px)

当您单击任何子按钮时，它们会通过 :target 触发其关联的模态。模态本身都提供了几种纯 HTML/CSS 方式来关闭模态：

点击模态后面的半透明背景
点击右上角的关闭按钮“x”
点击“取消”操作按钮

每个模态都是完全独特的，并由其关联的 .sub-button 触发。我还在模态样式背后构建了一些系统，其中包含 .modal-content、.modal-header 和 .modal-body 的全局样式，以及 .modal-close 的上下文样式类，当插入到模态的主元素中时，它显示为模态后面的可点击/可取消背景，而当包含在 .modal-content 元素中时，它在右上角显示为“x”。单击任一将关闭模态。

我今天添加的最后两个好东西：

具有动态样式的“新帖子”表单样式以智能地生成所需的间距量，以及用于存档和删除模式的简短警报模式的通用样式
显示在 #mega-button 上方的悬停工具提示。此工具提示无法单击，并且不会在功能上阻碍其后面的任何内容，因为它的 pointer-events 属性设置为 none。当鼠标悬停在 opacity: 0 或其任何后代上时，或者当模态打开时，通过通用同级组合器 (#mega-button)，它会淡化为 ~。

这是成品：

如果您希望在最终的 CSS 中保持所有这些计算动态，那么这个 SCSS 中的所有动态变量都可以简单地转换为 CSS 自定义属性。

Answer 5

您是否预先编写了任何代码，或者您只是在寻求教程？

如果是前者，这里有一些关于如何构建代码以使其工作的想法：

var el = $('a.button'); // the element you want to hover over
var hi = $('div.hidden'); // the div containing the hidden buttons

el.hover(function(){
    //do this when the mouse hovers over the link, eg
    hi.show('slide',{direction:'right'},250);
}, function(){
    //do this when the mouse leaves the link, eg
    hi.hide('slide',{direction:'left'},250);
});

Answer 6

`:target` 使用模态实现

具有来自 this answer 的一些样式的模态实现

.fab-container {
  position: fixed;
  bottom: 20px;
  left: 20px;
  z-index: 999;
  cursor: pointer;
}

.fab-icon-holder {
  width: 50px;
  height: 50px;
  border-radius: 100%;
  background: black;
  box-shadow: 0 6px 20px rgba(0, 0, 0, 0.2);
}

.fab-icon-holder:hover {
  opacity: 0.8;
}

.fab-icon-holder i {
  display: flex;
  align-items: center;
  justify-content: center;
  height: 100%;
  font-size: 25px;
  color: #ffffff;
}

.fab {
  width: 60px;
  height: 60px;
  background: #3F51B5;
}

.fab-options {
  list-style-type: none;
  margin: 0;
  position: absolute;
  bottom: 0px;
  left: 30px;
  opacity: 0;
  transition: all 0.3s ease;
  transform: scale(0);
  transform-origin: 85% left;
}

.fab:hover+.fab-options,
.fab-options:hover {
  opacity: 1;
  transform: scale(1);
}

.fab-options li {
  display: flex;
  justify-content: flex-end;
  padding: 5px;
}

:target {
  visibility: visible !important;
}

#modal {
  visibility: hidden;
  width: 80%;
  height: 80%;
  position: fixed;
  left: 10%;
  box-shadow: 0 0 3px black;
}

#modal .content {

}

#modal #close {
  position: absolute;
  top: 10px;
  right: 15px;
  font-size: 2em;
  cursor: pointer;
}

这是我的旧的（虽然样式很差）：

html,

}

.buttons {
  position: fixed;
  bottom: 10px;
  left: 10px;

}

.button {
  border-radius: 50%;
  width: 25px;
  height: 25px;
  cursor: pointer;
  transition: 1s;
}

.button {
  color: white;
}

.parent-button {
  box-shadow:0 0 3px #3F51B5;
  background-color: #3F51B5;
  padding: 1em;
  color: white;
}

.child-button {
  box-shadow:0 0 3px black;
  background-color: black;
  margin-left: 5px;
  padding:0.75em;
  opacity:0;
}
.child-button a{

}
.parent-button:hover~.child-button{

}

.child-button:hover{

滑出式

类型 1：宽度从 struct ContentView: View { @State var doIWantThisViewToShow: Bool = false var body: some View { VStack { Button("Show/Hide MyView") { doIWantThisViewToShow.toggle() } if doIWantThisViewToShow { MyView() .padding() } } } } 调整为适合内容的宽度。

0px

.material-icons {
