問題描述
我有一個(gè)使用這個(gè) CSS 的三角形 (JSFiddle):
I have a triangle (JSFiddle) using this CSS:
.triangle {
width: 0;
height: 0;
border-top: 0;
border-bottom: 30px solid #666699;
border-left: 20px solid transparent;
border-right: 20px solid transparent;
}
還有這個(gè) HTML:
<div class="triangle"></div>
這會(huì)形成一個(gè)三角形，但對(duì)角線是鋸齒狀和像素化的.我怎樣才能使它們光滑?(我能夠在 Safari 和 Chrome 中通過將它們打點(diǎn)來平滑它們，但這打破了 Firefox 和 IE 中的三角形.)
This makes a triangle, but the diagonal lines are jagged and pixelated. How can I make them smooth? (I was able to smooth them out in Safari and Chrome by making them dotted, but that broke the triangles in Firefox and IE.)
推薦答案
即使在純 CSS 中我們也可以得到平滑的對(duì)角線.
Even in pure CSS we can get the smooth diagonals.
.triangle {
width: 0;
height: 0;
border-top: 0;
border-bottom: 30px solid #666699;
border-left: 20px solid rgba(255, 255, 255, 0);
border-right: 20px solid rgba(255, 255, 255, 0);
}
您可以使用 rgba(255, 255, 255, 0) 來代替透明.這再次給出透明.但是 alpha=0 會(huì)產(chǎn)生平滑的對(duì)角線.
Instead of giving transparent you can make use of rgba(255, 255, 255, 0). This again gives transparent. But the alpha=0 makes smooth diagonals.
