HTML是網(wǎng)頁開發(fā)的基礎(chǔ)語言，JavaScript是一種常用的腳本語言，結(jié)合它們，我們可以創(chuàng)造出多種美觀而實用的特效。下面是一些常用的HTML和JavaScript特效代碼：

//1.鼠標(biāo)懸停特效
<script>
function changeColor(element, color){
element.style.backgroundColor = color;
}
</script>
<div onmouseover="changeColor(this, 'red')" onmouseout="changeColor(this, 'white')">
鼠標(biāo)懸停在這里
</div>
//2.輪播圖特效
<script>
var index = 0;
function changeImg(){
var imgs = document.getElementById("imgs");
var lists = document.getElementById("lists").getElementsByTagName("li");
for(var i=0; i<lists.length; i++){
lists[i].className = "";
}
index++;
if(index == imgs.children.length){
index = 0;
}
lists[index].className = "active";
imgs.style.left = -index*800 + "px";
}
var timer = setInterval(changeImg, 2000);
</script>
<div id="imgs">
<img src="img1.jpg">
<img src="img2.jpg">
<img src="img3.jpg">
</div>
<ul id="lists">
<li class="active"></li>
<li></li>
<li></li>
</ul>
