*The following techniques are all derived from "CSS Secrets" written by Lea Verou
Adaptive ellipse and rounded corner construction
To construct a circle on CSS, you only need to set the border-radius attribute value to half the side length.
nbsp;html><meta><title>border-radiustitle> <style> .borderRadius{ display: inline-block; background: #fb3; min-width: 200px; height: 200px; line-height: 200px; border-radius: 100px; /* 边长的一半 */box-sizing: border-box; padding:0 5px; }<style> <head> <body> <p class="borderRadius"> <p class="innerTxt">p>p>body>html></style> </title>
The display effect is as follows:
The above layout When we add too much content in innerTxt, we will get the following effect:
If we want an adaptive ellipse If so, then the border-radius should not be a fixed value. When we set the border-radius to 50%, the display effect is as follows:
This becomes an adaptive ellipse.
Here we give a comprehensive introduction to the properties of border-radius. Border-radius is an abbreviated property. Its expansion formula is border-top-left-radius, border-top-right-radius, border-bottom-right-radius, border-bottom-left-radius.
It also has a little-known feature: border-radius can specify horizontal and vertical radii separately, just use a slash ( / ) to separate the two values ( Circle fillets have equal horizontal and vertical radii and can be merged).
Combining these characteristics, the detailed expansion of border-radius:50%; should be border-radius:50% 50% 50% 50%/50% 50% 50% 50%. Next, we use our imagination to construct various graphics based on the known fillet characteristics. border-radius: 50% / 100% 100% 0 0 (when the corner radius is less than 4, css will automatically repeat it for you)border-radius:
.borderRadius{display: inline-block;background: rgba(255,160,220,.8); box-shadow: hsl(0, 0%, 60%) 0 3px 3px;min-width: 200px;height: 100px;line-height: 200px; border-radius: 50% 10% / 100% 10%; }
.borderRadius{display: inline-block;background: rgba(157, 255, 127, 0.8); box-shadow: hsl(0, 0%, 60%) 0 3px 3px;min-width: 160px;height: 100px; line-height: 200px;border-radius: 20% 20% 12% 12%/ 80% 80% 12% 12%; }
.borderRadius{display: inline-block;background: rgba(167, 255, 250, 0.8); box-shadow: hsl(0, 0%, 60%) 0 3px 3px;min-width: 160px;height: 100px; line-height: 200px;border-radius: 20% / 50%; }

两种方法:1、利用display属性,只需给元素添加“display:none;”样式即可。2、利用position和top属性设置元素绝对定位来隐藏元素,只需给元素添加“position:absolute;top:-9999px;”样式。

怎么制作文字轮播与图片轮播?大家第一想到的是不是利用js,其实利用纯CSS也能实现文字轮播与图片轮播,下面来看看实现方法,希望对大家有所帮助!

自适应布局又称“响应式布局”,是指可以自动识别屏幕宽度、并做出相应调整的网页布局;这样的网页能够兼容多个不同的终端,而不是为每个终端做一个特定的版本。自适应布局是为解决移动端浏览网页而诞生的,能够为使用不同终端的用户提供很好的用户体验。

实现方法:1、使用“:active”选择器选中鼠标点击图片的状态;2、使用transform属性和scale()函数实现图片放大效果,语法“img:active {transform: scale(x轴放大倍数,y轴放大倍数);}”。

css3中的动画效果有变形;可以利用“animation:动画属性 @keyframes ..{..{transform:变形属性}}”实现变形动画效果,animation属性用于设置动画样式,transform属性用于设置变形样式。

在css3中,可以利用“animation-timing-function”属性设置动画旋转速度,该属性用于指定动画将如何完成一个周期,设置动画的速度曲线,语法为“元素{animation-timing-function:速度属性值;}”。

css3线性渐变可以实现三角形;只需创建一个45度的线性渐变,设置渐变色为两种固定颜色,一个是三角形的颜色,另一个为透明色即可,语法“linear-gradient(45deg,颜色值,颜色值 50%,透明色 50%,透明色 100%)”。
