[英]Adding CSS Trapezoid Shape :After Button
我正在嘗試為客戶端創建按鈕樣式,但似乎無法使用after偽類使其工作。
<style>
$varBase: 40px;
$imsblue: #012169;
$imsgrey: #012169;
body {
background:grey;
}
.btn {
position: relative;
float: left;
height: $varBase;
font-family: sans-serif;
text-align: center;
line-height: $varBase;
color: white;
white-space: nowrap;
text-transform: uppercase;
background: $imsblue;
&:before {
float: left;
content:"";
width: ($varBase/4);
height: ($varBase/2);
}
&:after {
position: absolute;
content:"";
height: ($varBase/2);
border-left: ($varBase/2) solid $imsblue;
border-bottom: ($varBase/2) solid transparent;
}
a {
color: white;
text-decoration:none;
padding: ($varBase/4) ($varBase/2);
margin-right: -10px;
}
}
.btn3 {
display: inline;
color: white;
background: linear-gradient(135deg, rgba(1,33,105,1) 0%, rgba(1,33,105,1) 93%, rgba(30, 87, 153, 0) 93%, rgba(30, 87, 153, 0) 100%);
outline: 0;
border: 0;
padding: 10px 0px;
a {
color: inherit ;
text-transform: uppercase;
text-decoration:none;
padding: ($varBase/4) $varBase;
}
}
</style>
<div class="btn"><a href="#">Click to Submit</a></div>
<div class="btn3"><a href="#">Click to Submit</a></div>
我可以使用兩個DIV來顯示它,但是我只需要一個類就可以使用它。 有人可以幫我看看我在做什么錯嗎?
它應該看起來像這樣(當然不包括顏色和大小):
我相信缺少的關鍵元素是您需要在:after
偽類中包含content:""
。 請參見下面的示例。
.btn { height: 40px; background: red; width: 128px; float:left; } .btn:after { width: 0px; height: 20px; border-left: 20px solid red; border-bottom: 20px solid white; float:right; content:""; }
<div class="btn">Button</div>
這將起作用-我不得不將您的SCSS轉換為CSS,但是很清楚。
.btn { height: 40px; width: 200px; background: red; position: relative; /* work as container */ } .btn:after { content: ''; /* needed */ display: block; position: absolute; /* position to container */ right: 0; bottom: 0; border-left: 20px solid red; border-bottom: 20px solid white; }
<div class="btn">Button</div>
不幸的是,您不能有“透明”疊加層,它只會起作用。 我不得不用白色。
我找到了一種解決方案,該解決方案在透明的“剪切”位置有效。 您可以為按鈕使用常規背景或圖像背景:
<div class="buttoncut gon">My button</div>
CSS:
.gon {
width: 220px;
height: 220px;
background: darkblue;
background-size: 220px 220px;
/* Text styling */
line-height: 220px;
text-align: center;
font-family: sans-serif;
font-size: 15px;
font-weight: bold;
letter-spacing: 6px;
color: beige;
}
.gon:hover {
color: #fff;
text-shadow: 0 0 10px white;
}
.buttoncut {
height: 200px;
-webkit-clip-path: polygon(0% 0%, 100% 0, 100% 50%, 60% 100%, 0% 100%); clip-path: polygon(0% 0%, 100% 0, 100% 50%, 60% 100%, 0% 100%);
-moz-clip-path: polygon(0% 0%, 100% 0, 100% 50%, 60% 100%, 0% 100%); clip-path: polygon(0% 0%, 100% 0, 100% 50%, 60% 100%, 0% 100%);
-ms-clip-path: polygon(0% 0%, 100% 0, 100% 50%, 60% 100%, 0% 100%); clip-path: polygon(0% 0%, 100% 0, 100% 50%, 60% 100%, 0% 100%);
clip-path: polygon(0% 0%, 100% 0, 100% 50%, 60% 100%, 0% 100%); clip-path: polygon(0% 0%, 100% 0, 100% 50%, 60% 100%, 0% 100%);
}
我使用此生成器來獲取正確的多邊形CSS: http : //bennettfeely.com/clippy/
您可以使用漸變來實現此目的,這樣就可以將其應用於任何元素(這是通過button元素完成的):
html,body{ background:red; } button { background: -moz-linear-gradient(-45deg, rgba(30, 87, 153, 1) 0%, rgba(30, 87, 153, 1) 89%, rgba(30, 87, 153, 0) 90%, rgba(30, 87, 153, 0) 100%); /* FF3.6+ */ background: -webkit-gradient(linear, left top, right bottom, color-stop(0%, rgba(30, 87, 153, 1)), color-stop(89%, rgba(30, 87, 153, 1)), color-stop(90%, rgba(30, 87, 153, 0)), color-stop(100%, rgba(30, 87, 153, 0))); /* Chrome,Safari4+ */ background: -webkit-linear-gradient(-45deg, rgba(30, 87, 153, 1) 0%, rgba(30, 87, 153, 1) 89%, rgba(30, 87, 153, 0) 90%, rgba(30, 87, 153, 0) 100%); /* Chrome10+,Safari5.1+ */ background: -o-linear-gradient(-45deg, rgba(30, 87, 153, 1) 0%, rgba(30, 87, 153, 1) 89%, rgba(30, 87, 153, 0) 90%, rgba(30, 87, 153, 0) 100%); /* Opera 11.10+ */ background: -ms-linear-gradient(-45deg, rgba(30, 87, 153, 1) 0%, rgba(30, 87, 153, 1) 89%, rgba(30, 87, 153, 0) 90%, rgba(30, 87, 153, 0) 100%); /* IE10+ */ background: linear-gradient(135deg, rgba(30, 87, 153, 1) 0%, rgba(30, 87, 153, 1) 89%, rgba(30, 87, 153, 0) 90%, rgba(30, 87, 153, 0) 100%); /* W3C */ filter: progid: DXImageTransform.Microsoft.gradient(startColorstr='#1e5799', endColorstr='#001e5799', GradientType=1); /* IE6-9 fallback on horizontal gradient */ outline:0; border:0; padding:5px; }
<button>PressMe</button>
div { position: relative; display:inline-block; padding:5px; background:gray; } div:after{ content:""; position:absolute; border-bottom:10px solid blue; border-left:10px solid transparent; bottom:0; right:0; } html,body{ background:blue; }
<div>Press Me!</div>
button { padding: 10px; height: 60px; width: 60px; -webkit-clip-path: polygon(0% 0%, 100% 0, 100% 75%, 75% 100%, 0% 100%); clip-path: polygon(0% 0%, 100% 0, 100% 75%, 75% 100%, 0% 100%); } html,body{ background:green; }
<button>press me!!!</button>
通過使用以下代碼段,您可以制作一個很棒的按鈕,該按鈕不受長度的影響!
button { position: relative; border: 0; outline: 0; height: 20px; background: gray; } button:after { position: absolute; content: ""; right: -10px; width: 0px; height: 0px; bottom: 0; border-bottom: 10px solid transparent; border-left: 10px solid gray; } button:before { position: absolute; content: ""; right: -10px; width: 10px; height: 10px; top: 0; background: gray; } html, body { background: red; } /*HOVER EFFECTS*/ button:hover, button:hover:before { background: yellow; } button:hover:after { border-left: 10px solid yellow; }
<button>press me and plus i can get really long!</button>
