如何在 HTML 中当一个元素悬停时影响其他元素?
若要当一个元素悬停时影响其他元素,一个元素应在另一个元素内部,即父元素-子元素或同级元素。在将鼠标悬停在一个元素上时,另一个元素的属性应发生改变,即悬停效果可见。
当一个元素悬停时改变另一个元素的颜色
举例
在此示例中,当鼠标悬停在 div 中的两个框上时,我们将改变其颜色 −
<!DOCTYPE html> <html> <head> <style> .parent { width: 500px; height: 150px; background-color: orange; } .child { margin-left: 39px; width: 100px; height: 40px; background-color: blue; color: white; } div { border: 3px solid red; } .parent:hover .child { background-color: green; } </style> </head> <body> <h1>Change the color</h1> <p> Keep the mouse cursor inside the orange colored div to change the color of the two blue boxes.</p> </h3> <div class="parent">In the div <div class="child"> Box1 </div> <br> <div class="child"> Box2 </div> <br> </div> </body> </html>
当 div 悬停时改变按钮元素的颜色
举例
在此示例中,当 div 悬停时,我们将改变按钮元素的颜色 −
<!DOCTYPE html> <html> <head> <style> body { text-align: center; } .parent { width: 600px; height: 200px; background-color: blue; } .child { width: 30px; height: 30px; background-color: grey; } div { outline: 1px solid black; } .parent:hover .child { background-color: yellow; } .child { background-color: orange; border: none; padding: 50px 80px; margin-top: 40px; text-align: center; text-decoration: none; display: inline-block; font-size: 16px; } </style> </head> <body> <h1>Change the color</h1> <p> Keep the mouse cursor inside the blue colored div to change the color of the orange box to yellow.</p> </h3> <div class="parent"> <button class="child"> Box </button> </div> </body> </html>
