我想减小六边形形状元素的大小,但是我不能。
.r-hex {
overflow: hidden;
display: inline-block;
width: 20em;
height: 17.32em;
transform: rotate(-30deg) skewX(30deg);
border-radius: 10px;
margin-top: 2rem;
}
.r-hex *,
.r-hex *::before {
display: block;
overflow: hidden;
width: inherit;
height: inherit;
border-radius: inherit;
}
.r-hex-inner,
.r-hex-inner-2 {
transform: skewX(-30deg) rotate(60deg) skewX(30deg);
}
.r-hex-inner-2 {
background: #2388ed;
content: '';
}
.r-hex-inner-2::before {
margin-top: -1.5em;
width: 20em;
height: 20em;
transform: skewX(-30deg) rotate(-90deg);
background: url(https://s.ftcdn.net/v2013/pics/all/curated/RKyaEDwp8J7JKeZWQPuOVWvkUjGQfpCx_cover_580.jpg?r=1a0fc22192d0c808b8bb2b9bcfbf4a45b1793687);
background-size: cover;
text-align: center;
content: '';
}
<div class="r-hex">
<div class="r-hex-inner">
<div class="r-hex-inner-2"></div>
</div>
</div>
当我更改20em
的宽度和高度时,我失去了形状的半径。
所以我的问题是如何减小形状的大小而不损坏形状?
答案 0 :(得分:0)
根据我的评论,如果要更改六边形的宽度,则需要相应缩放代码段中的所有em
值。假设您要设置新的宽度10em
。由于您是从20em
缩小到10em
(即大小的一半),因此缩放比例为0.5。因此,所有绝对单位(px,em等)都需要按相同的因子进行缩放。
我在下面的代码中注释了所有需要进行缩放的地方。该线程中的另一个答案恰巧错过了一些单元,从而导致外观不正确。
.r-hex {
overflow: hidden;
display: inline-block;
/* Originally 20em, scaled by 0.5x */
width: 10em;
/* Originally 17.32em, scaled by 0.5x */
height: 8.66em;
transform: rotate(-30deg) skewX(30deg);
/* Originally 10px, scaled by 0.5x */
border-radius: 5px;
/* Originally 2rem, scaled by 0.5x */
margin-top: 1rem;
}
.r-hex *,
.r-hex *::before {
display: block;
overflow: hidden;
width: inherit;
height: inherit;
border-radius: inherit;
}
.r-hex-inner,
.r-hex-inner-2 {
transform: skewX(-30deg) rotate(60deg) skewX(30deg);
}
.r-hex-inner-2 {
background: #2388ed;
content: '';
}
.r-hex-inner-2::before {
/* Originally -1.5em, scaled by 0.5x */
margin-top: -0.75em;
/* Originally 20em, scaled by 0.5x */
width: 10em;
/* Originally 20em, scaled by 0.5x */
height: 10em;
transform: skewX(-30deg) rotate(-90deg);

实际上,您也可以使用JavaScript进行所有这些计算:没有什么是不可能的。请注意,下面的示例使用CSS自定义属性(也称为CSS变量),到目前为止,只有常绿的浏览器支持它们(即不支持IE11)。
诀窍是将所有引用转换为绝对单位,以依赖于--scale
CSS变量并将其与calc()
组合。通过更改此CSS变量,您可以轻松调整六边形的大小,而不必担心自己手动重新计算值:
document.querySelector('#scale').addEventListener('input', e => {
// Get the scale and convert it to a number
const scale = +e.target.value;
const hexElements = document.querySelectorAll('.r-hex');
hexElements.forEach(hexElement => {
hexElement.style.setProperty('--scale', scale);
});
});
.r-hex {
/* This CSS property can be manipulated by JS */
--scale: 1;
overflow: hidden;
display: inline-block;
width: calc(20em * var(--scale));
height: calc(17.32em * var(--scale));
transform: rotate(-30deg) skewX(30deg);
border-radius: calc(10px * var(--scale));
margin-top: calc(2rem * var(--scale));
transition: all .25s ease-in-out;
}
.r-hex *,
.r-hex *::before {
display: block;
overflow: hidden;
width: inherit;
height: inherit;
border-radius: inherit;
}
.r-hex-inner,
.r-hex-inner-2 {
transform: skewX(-30deg) rotate(60deg) skewX(30deg);
}
.r-hex-inner-2 {
background: #2388ed;
content: '';
}
.r-hex-inner-2::before {
margin-top: calc(-1.5em * var(--scale));
width: calc(20em * var(--scale));
height: calc(20em * var(--scale));
transform: skewX(-30deg) rotate(-90deg);
background: url(https://s.ftcdn.net/v2013/pics/all/curated/RKyaEDwp8J7JKeZWQPuOVWvkUjGQfpCx_cover_580.jpg?r=1a0fc22192d0c808b8bb2b9bcfbf4a45b1793687);
