HomeWeb Front-endHTML Tutorial效果实现案例1 - 林七七

今天要介绍的是三角形的使用案例,照旧先给效果图。
解释:
1、这个正方形上的字就省略不说了,但要控制好文字块的宽度,以免被上面的"已点"提示挡到。
2、关于“已点”提示,我是如下实现的:大div设置“position:relative;”,小div设置"position:absolute;";  要设置好小div的width和height,再进行小div的旋转transform和top、right等细节的调整即可完成。
 
Tip:
1、旋转时可重新设定旋转中心,用transform-origin(具体使用细节请自行搜索),默认旋转中心是元素自己的中心位置;
2、小div的高度、宽度、top、right等值都会影响旋转效果,旋转角度默认45deg,其它可根据效果自行调整。
3、记得加上overflow:hidden; 隐藏掉大div之外的小div。
 
效果图如下所示:
 
html代码如下:
<span style="color: #0000ff;"><span style="color: #800000;">div </span><span style="color: #ff0000;">id</span><span style="color: #0000ff;">="container"</span><span style="color: #0000ff;">></span>
    <span style="color: #0000ff;"><span style="color: #800000;">div </span><span style="color: #ff0000;">id</span><span style="color: #0000ff;">="square"</span><span style="color: #0000ff;">></span>
        <span style="color: #0000ff;"><span style="color: #800000;">div </span><span style="color: #ff0000;">id</span><span style="color: #0000ff;">="tip"</span><span style="color: #0000ff;">></span>已点<span style="color: #0000ff;"></span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span>
    <span style="color: #0000ff;"></span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"></span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span></span></span></span>
 
CSS代码如下:
