這篇文章主要介紹了教你用html+css實(shí)現(xiàn)炫光倒影按鈕,用簡單的代碼分享有趣的CSS創(chuàng)意特效,放松放松心情,一起來學(xué)習(xí)一下如何制作吧

話不多,先看效果:

在這里插入圖片描述

實(shí)現(xiàn)過程(完整源碼在最后):

1 老樣子,定義基本樣式:

   *{
             margin: 0;
            padding: 0;
            box-sizing: border-box;
            font-family: 'fangsong';
        }
        body{
            height: 100vh;
            display: flex;
            align-items: center;
            justify-content: center;
            background-color: rgb(0, 0, 0);
        }

font-family: ‘fangsong’; 仿宋字體。
display: flex;
align-items: center;
justify-content: center; flex布局,讓按鈕在屏幕居中。

2.定義基本標(biāo)簽:

        <a href="#" class="item item1">
            aurora
            <span></span>
            <span></span>
            <span></span>
            <span></span>
        </a>
        <a href="#" class="item item2">
            aurora
            <span></span>
            <span></span>
            <span></span>
            <span></span>
        </a>
        <a href="#" class="item item3">
            aurora
            <span></span>
            <span></span>
            <span></span>
            <span></span>
        </a>

3個a標(biāo)簽就對應(yīng)3個按鈕,每個按鈕里4個span就是環(huán)繞按鈕的4條邊。
且都有個公共的選擇器 .item 和 只屬于自己的選擇器。

3.定義每個按鈕的基本樣式:

 .item{
            position: relative;
            margin: 50px;
            width: 300px;
            height: 80px;
            text-align: center;
            line-height: 80px;
            text-transform: uppercase;
            text-decoration: none;
            font-size: 35px;
            letter-spacing: 5px;
            color: aqua;
            overflow: hidden;
            -webkit-box-reflect: below 1px linear-gradient( transparent,rgba(6, 133, 133,0.3));
        }

text-align: center;文字對齊方式。
line-height: 80px; 字行高。
text-transform: uppercase; 字母為大寫。
text-decoration: none; 去掉a標(biāo)簽?zāi)J(rèn)下劃線。
letter-spacing: 5px; 每個字符間的距離。
overflow: hidden;溢出隱藏。
-webkit-box-reflect: below 1px linear-gradient( transparent,rgba(6, 133, 133,0.3)); 這個屬性能實(shí)現(xiàn)倒影效果。

4. 鼠標(biāo)經(jīng)過按鈕樣式改變:

 .item:hover{
            background-color: aqua;
            box-shadow:0 0 5px aqua,
            0 0 75px aqua,
            0 0 155px aqua;
            color: black;
        }

box-shadow:0 0 5px aqua,
0 0 75px aqua,
0 0 155px aqua; 陰影,寫多行可以疊加更亮。

5.設(shè)置環(huán)繞按鈕的4根線上面那條的樣式:

.item span:nth-of-type(1){
            position: absolute;
            left: -100%; 
            width: 100%;
            height: 3px;
            background-image: linear-gradient(to left,aqua ,transparent);
            animation: shang 1s linear infinite;
        }
        @keyframes shang{
            0%{
                left:-100%;
            }
            50%,100%{
                left:100%;
            }
        }

position: absolute;
left: -100%; 定位在對應(yīng)位置。
background-image: linear-gradient(to left,aqua ,transparent); 線性漸變顏色。
animation: shang 1s linear infinite; 動畫屬性,讓它動起來。

5.以此類推,設(shè)置環(huán)繞按鈕的其它3根樣式:

  .item span:nth-of-type(2){
            position: absolute;
            top: -100%;
            right: 0;
            width: 3px;
            height: 100%;
            background-image: linear-gradient(to top,aqua ,transparent);
            animation: you 1s linear infinite;
            animation-delay: 0.25s;
        }
        @keyframes you{
            0%{
                top:-100%;
            }
            50%,100%{
                top:100%;
            }
        }
        .item span:nth-of-type(3){
            position: absolute;
            right: -100%;
            bottom: 0;
            width: 100%;
            height: 3px;
            background-image: linear-gradient(to right,aqua ,transparent);
            animation: xia 1s linear infinite;
            animation-delay: 0.5s;
        }
        @keyframes xia{
            0%{
                right:-100%;
            }
            50%,100%{
                right:100%;
            }
        }
        .item span:nth-of-type(4){
            position: absolute;
            bottom: -100%;
            left: 0;
            width: 3px;
            height: 100%;
            background-image: linear-gradient(to bottom,aqua ,transparent);
            animation: zuo 1s linear infinite;
            animation-delay: 0.75s;
        }
        @keyframes zuo{
            0%{
                bottom:-100%;
            }
            50%,100%{
                bottom:100%;
            }
        }

animation-delay: 0.75s; 動畫延遲執(zhí)行。每條線對應(yīng)延遲一段時間,形成時間差,形成環(huán)繞效果。

6.給第一,第三個按鈕設(shè)置其它顏色:

 .item1{
            filter: hue-rotate(100deg);
        }
        .item3{
            filter: hue-rotate(250deg);
        }

filter: hue-rotate(100deg); 用色相旋轉(zhuǎn),這樣不管背景還是陰影顏色都變了。
