咕咕了好久啦，今天使用原生HTML+CSS+JS做一个很简单的个人定制的导航主页吧！

先看下完整的效果图吧！

接下来的文章将逐步带领大家制作，现在太晚了，就精简了下，删除了部分动画效果，项目整体非常简单！

首先设置我们的背景。
在body中插入背景即可。

• index.html

• style.css

*{
    margin: 0;
    padding: 0;
}


html, body {
    height:100%;
    overflow:auto; 
}

body{
    
    background: no-repeat center fixed;
    
    -webkit-background-size:cover;
    background-size:cover;
    
    transition:background-image 1s;
    font-family: Sans-serif;
}

• index.js

//创建数组存放背景url
var bgs = new Array('url("images/bg01.jpg")','url("images/bg02.jpg")','url("images/bg04.jpg")','url("images/bg05.jpg")','url("images/bg08.jpg")','url("images/bg25.jpg")','url("images/bg09.jpg")','url("images/bg10.jpg")','url("images/bg12.jpg")','url("images/bg13.jpg")','url("images/bg25.jpg")','url("images/bg15.jpg")','url("images/bg17.jpg")','url("images/bg19.jpg")','url("images/bg20.jpg")','url("images/bg21.jpg")','url("images/bg22.jpg")','url("images/bg23.jpg")','url("images/bg25.jpg")');
}

界面主要由三部分组成：

• 头部：导航栏，时间，搜索框

• 主体：各站图标
  

• 底部：鼠标悬浮时出现的图标
  

Header部分由导航栏,时间，以及搜索框组成。
图标使用的是font-awesome库里的图。

首先添加导航栏中的元素

index.html:

 

    

       
                   class="icon">
                       
                   
          class="text">home
       
    
    

       
                   class="icon">
                       
                   
          class="text">background
       
    
    

       
                   class="icon">
                       
                   
          class="text">note
       
    
    

       

                   class="icon">
                       
                   
          class="text">ball
       
    
    

       
                   class="icon">
                       
                   
          class="text">about
       
    
 

给当导航栏图标设置样式

style.css:

.tabbar{
    height: 100vh;
    
    display: flex;
    justify-content: center;
    align-items: center;
    
    position: relative;
    width: 350px;
    height: 70px;
    margin: 0 auto;
}

.tabbar ul{
    
    display: flex;
}
.tabbar ul li{
    list-style: none;
    width: 70px;
    height: 70px;
    position: relative;
    z-index: 1;
}
.tabbar ul li a{
    
    display: flex;
    justify-content: center;
    align-items: center;
    
    flex-direction: column;
    color: #fff;
    text-align: center;
}
.tabbar ul li a .icon{
    line-height: 70px;
    font-size: 30px;
    
    transition: 0.5s;
}
.tabbar ul li a .text{
    
    position: absolute;
    font-size: 12px;
    bottom: 13px;
    
    transition: 0.5s;
    
    transform: scale(0);
}
.tabbar ul li.active a .icon{
    font-size: 23px;
    
    transform: translateY(-10px);
}
.tabbar ul li.active a .text{
    
    transform: scale(1);
}

设置导航栏图标的点击事件
当鼠标点击元素时，添加或移除active样式即可。

index.js:

//设置导航栏图标的点击时间
//点击更改背景
function changeBg(){
    document.getElementById('bgid').style.backgroundImage = bgs[Math.round(Math.random()* (bgs.length-1))];
}

// 获取所有.item元素
let items=document.querySelectorAll(".item");
// 设置当前选中项样式的方法
function setActive(){
    // 遍历所有.item元素,移除active样式
    items.forEach((item)=>{
        item.classList.remove("active");
    })
    // 为当前选中项添加active样式
    this.classList.add("active");
}
// 遍历所有.item元素,分别为其设置点击事件
items.forEach((item)=>{
    item.addEventListener("click",setActive);
})

现在打开浏览器页面就可以看到下图中的效果啦！(有免费的制作图片的软件嘛QAQ)

接下来给导航栏再添加一个点击时的背景，显得更好看一些

我们在header部分中的

列表内添加一个用于存放该背景

完整代码如下,index.html:

 

    

       
                   class="icon">
                       
                   
          class="text">home
       
    
    

       
                   class="icon">
                       
                   
          class="text">background
       
    
    

       
                   class="icon">
                       
                   
          class="text">note
       
    
    

       

                   class="icon">
                       
                   
          class="text">ball
       
    
    

       
                   class="icon">
                       
                   
          class="text">about
       
    
 
    

设置添加的导航栏背景样式。

.active-bg{
    position: absolute;
    left: 0;
    top: 0;
    width: 70px;
    height: 70px;
    border-radius: 50%;
    
    background-color: var(--c);
    box-shadow: 0 10px 15px var(--cc);
    transition: 0.5s;
}

.tabbar ul li:nth-child(1).active ~ .active-bg{
    --c:#ffa502;
    --cc:#ffa50299;
    left: 0;
}
.tabbar ul li:nth-child(2).active ~ .active-bg{
    --c:#ff6348;
    --cc:#ff634899;
    left: calc(1 * 70px);
}
.tabbar ul li:nth-child(3).active ~ .active-bg{
    --c:#2ed573;
    --cc:#2ed57399;
    left: calc(2 * 70px);
}
.tabbar ul li:nth-child(4).active ~ .active-bg{
    --c:#1e90ff;
    --cc:#1e90ff99;
    left: calc(3 * 70px);
}
.tabbar ul li:nth-child(5).active ~ .active-bg{
    --c:#ff6b81;
    --cc:#ff6b8199;
    left: calc(4 * 70px);
}

现在打开浏览器，就可以看到下图中的效果啦！


3 时间

接下来 添加时间以及小鸭鸭（也可以添加自己喜欢的图片或者不添加）

首先添加元素

index.html:

    


    

        
0
        
0
        
:
        
0
        
0
        
:
        
0
        
0
    

运行效果：


设置图片的样式

style.css：

.img{
    width:1200px;
    height:100px;
    position: relative;
    margin: 0 auto;
}

.img  img{
    width:60px;
    height:60px;
    position: absolute;
    top:50%;
    left:40%;
    margin-top:-30px ;
    margin-left:-30px ;
}

设置时间的样式

style.css：

.img .clock{
    width:60px;
    height:60px;
    position: absolute;
    top:50%;
    left:45%;
    margin-top:-30px ;
    margin-left:-30px ;
}

.clock{
    display: flex;
}
.clock p{
    
    font-size: 50px;
    color: #fff;
    text-align: center;
    
    font-family: "Kanit";
    font-weight: 900;
    
    text-shadow: 0 1px 0 #deafaf,
    0 2px 0 #bda8a8,
    0 3px 0 #d8a1a1,
    0 4px 0 #d59999,
    0 5px 0 #d29292,
    0 6px 0 #cf8b8b,
    0 7px 0 #cc8484,
    0 8px 0 #c97d7d,
    0 0 5px rgba(231,156,156,0.05),
    0 -1px 3px rgba(231,156,156,0.2),
    0 9px 9px rgba(231,156,156,0.3),
    0 12px 12px rgba(231,156,156,0.3),
    0 15px 15px rgba(231,156,156,0.3);
}

运行效果：

获取当前时间

index.js:

function myTime(){
    let time=new Date();
    let hh=time.getHours();  //时
    let mm=time.getMinutes();  //分
    let ss=time.getSeconds();  //秒
    // Math.floor() 向下取整
    document.getElementById("1").innerText=Math.floor(hh/10);
    document.getElementById("2").innerText=hh%10;
    document.getElementById("4").innerText=Math.floor(mm/10);
    document.getElementById("5").innerText=mm%10;
    document.getElementById("7").innerText=Math.floor(ss/10);
    document.getElementById("8").innerText=ss%10;
}
// 一秒执行一次
setInterval(myTime,1000);

运行效果：


4. 搜索框

接下来加入我们的搜索框

设置搜索框样式

.midbox{
    float: left;
    display: inline-block;
    background:transparent;
    width: 100%;
    height: 40px;
}
.midbox form{
    width: 600px;
    height:40px;
    margin:0 auto;
}
#seaid{
    float:left;
    width: 550px;
    height: 40px;
    outline: none;
    border:none;
    font-size: 18px;
    text-indent: 1em;
    background:rgba(255,255,255,.2);
}
#subid{
    float:left;
    width: 50px;
    height: 36px;
    outline: none;
    background:transparent;
    border:0;
    font-size: 18px;
    background: url("../images/search.svg") no-repeat center;
    background-position-y: 4px;
    cursor:pointer;

}

运行效果：

至此我们的头部就完成啦！

三、主体

主体和footer也都很简单，基本上都是一些图标和样式设置。

添加元素
index.html:

设置样式：
style.css

li{
    list-style: none;
    display: inline-block;
}
.container{
    width: 1080px;
    margin: 0 auto;
    margin-top:40px;

}
.container ul {
    width: 100%;
    height: 100%;
}
.container ul li{
    margin:20px;
    width: 60px;
    height: 60px;
    background-color: rgba(0,0,0,0);
    border-radius: 5px;

    text-align: center;
}
.container ul li:hover{
    transform:translateY(-3px);
    transition:all 0.2s;
}
.container ul li a img{
    margin:5px;
    width: 48px;
    height: 48px;
    opacity: 1;
}

完成后的效果：


四、底部

与主题部分相似，多了一个鼠标悬浮于底部的hover效果，都是较为基础的。

index.html:

style.css

footer{
    position:fixed;
    width: 100%;
    height: 100px;
    bottom: -90px;
    text-align: center;
    z-index:98;
}
footer ul{
    position:absolute;
    height: 60px;
    width: 950px;
    top: -60px;
    left: 225px;
    list-style: none;
    background-color: rgba(0,0,0,.3);
    border-radius:30px;
    transform:translateY(70px);
    transition:all .3s;

}
footer:hover ul{
    transform:translateY(0px);
    transition:all .3s;
}
footer ul li{
    float: left;
    width: 60px;
    height: 60px;
    margin-top: 2px;
    margin-left: 40px;
    border-radius:50%;
    cursor:pointer;

}
footer ul li img{
    width: 45px;
    height: 45px;
    margin:5px;

}
footer ul li:hover{
    transform:scale(1.6);
    transform-origin:50% 100%;
    transition:all .1s;
}

至此我们的个人定制导航主页就完成啦！

五、背景泡沫球特效

添加元素
添加位置如下，最后会再放上全部代码哒！

• 三个元素分别是用来容纳球球的div，以及用来启动/暂停/清除球球的按钮

index.html:

设置球球的样式，以及按钮的样式
可以新建一个css文件，使结构清晰点，当然写在原来的style.css里也是没有问题的。
ball.css

 .ballbox{
      position:absolute;
      width:1180px;
      height:500px;
	  top:60px;
	  left:65px;
	  z-index:-100;
	  transition:all .3s;
	  }
	  .ballBtns{
		position:absolute;
		width: 65px;
		height: 100px;
		top: 80px;
		left: -65px;
		z-index:9999;
		transition:all .3s;
	  }
 .ball{
      position:absolute;
      border-radius:50%;
	  opacity:.8;

    }
 .clear_btn,.auto_btn{
      position:absolute;
      width:65px;
      height:35px;
      top:60px;
      left:0px;
	 border-radius: 24px;
	 color: #fff;
	 font-family: "Kanit";
	 font-weight: 900;
	 
	 text-shadow: 0 1px 0 #deafaf;
	  border:none;
	 box-shadow: 0 10px 10px rgba(0,0,0,.3);
	 outline:none;
	 cursor: pointer;
 }

 .auto_btn{
		top:0px;
	 background-image: linear-gradient(to right, #f441a0, #09a8f4, #ffeb3b,#03a9f4);
	 
	 background-size: 400%;
 }
 .clear_btn{
	 background-image: linear-gradient(to right, #09a8f4, #ffeb3b, #f441a0,#03a9f4);
	 
	 background-size: 400%;
 }

设置泡沫球的添加、清除、停止添加，球的移动以及按钮的弹出
index.js:

//获取元素
var ballbox =document.querySelector('.ballbox');
var clearBtn =document.querySelector('.clear_btn');
var auto =document.querySelector('.auto_btn');
var colors=['#ef9a9a','#F48FB1','#CE93D8','#B39DDB','#9FA8DA','#90CAF9','#81D4FA','#80DEEA','#80CBC4','#A5D6A7','#C5E1A5','#FFCC80','#FFAB91','#BCAAA4','#B0BEC5'];
var flag = true;
var balls = null;
var count = 0;
//自动添加 停止添加
function autoBtn(){
    if(flag){
        timer = setInterval(addBall,150);
        auto.value ='Stop';
        auto.style.backgroundColor ='red';
        flag = false;

    }else{
        clearInterval(timer);
        auto.style.backgroundColor ='#00ACC1';
        auto.value ='Start';
        flag = true;
    }
}
//创建新的
function addBall(){
    var ball = document.createElement('div');
    ball.setAttribute('class','ball');
    ball.style.background= "radial-gradient(circle at 75px 75px, "+colors[parseInt(Math.random()*colors.length)]+",#fff)";
    ballbox.appendChild(ball);
    count += 1;

    //控制球移动
    var top = parseInt(Math.random()*400);
    var left =  parseInt(Math.random()*900);
    ball.style.width = parseInt(Math.random()*50+50) +'px';
    ball.style.height = ball.style.width;
    ball.style.top = top +'px';
    ball.style.left = left +'px';
    var x = 5;
    var y = 8;

    running = setInterval(function clearBalls(){
        top += y ;
        left += x;
        if(top < 0  || top> (ballbox.offsetHeight - ball.offsetHeight)){
            y = -y ;
        }
        if(left< 0 || left> (ballbox.offsetWidth - ball.offsetWidth)){
            x = -x;
        }

        ball.style.top = top +'px';
        ball.style.left = left +'px';
    },100)

}
//清除球
// clearBtn.onclick =
function clearBalls(){
    var balls = document.getElementsByClassName('ball');
    clearInterval(timer);
    auto.style.backgroundColor ='#00ACC1';
    auto.value ='Start';
    flag = true;
    while(balls.length != 0){
        balls.length-- ;
        ballbox.removeChild(ballbox.children[0]);
    }
}

//弹出操作按钮
var btns =document.getElementById('btns');
var flag2 = true;
function ballBtn(){
    if(!flag2){
        btns.style.transform = 'translateX(0px)';
        flag2 = true;

    }else{
        btns.style.transform = 'translateX(65px)';

        flag2 = false;
    }
}

完成这一步，就可以看到我们的泡沫球动画啦！

效果如下：


六、note小便签

添加元素
第一步当然还是将便签元素添加进来啦！
分别是文本域、添加便签按钮、关闭便签栏按钮、删除便签按钮。

代码如下：

设置样式
大家按照自己喜好，设置合适的样式就好啦。
style.css:

.btm{
	border-radius: 20px;
	position: absolute;
	width:570px;
	height: 410px;
	top:90px;
	left:-570px;
	margin-top: 100px;
	background-color: rgba(255,255,255,.9);
	transition:all .3s;
	z-index:99;
	}
#txt{
	float: left;
	width: 425px;
	height: 50px;
	padding: 5px;
	border:0;
	margin:20px;
	margin-bottom: 0px;
	color:black;
	font-size: 6px;
	background-color:#ccc;
	outline: none;	
	background-color: rgba(0,0,0,.3);			
}
#txt::-webkit-input-placeholder, #txt textarea::-webkit-input-placeholder {
  color: black;
  font-size: 10px;
}
.btm #add{
	float: left;
	width: 50px;
	height: 60px;
	margin-top: 20px;
	margin-left: -5px;
	outline: none;
	border:0;
	color:#fff;
	cursor: pointer;
	background-color: rgba(0,0,0,.3);
}

#closeBox{
	float: right;
	width: 32px;
	height: 32px;
	margin-top: 0;
	margin-right: 0;
	outline: none;
	border:0;
	color:#fff;
	cursor: pointer;
	background:url('../images/close.png') no-repeat;
	background-color: rgba(0,0,0,0);
	border-radius:50%;
}
.notes  li{
	position: relative;
	float: left;
	width: 85px;
	height: 85px;
	border:0;
	margin:20px;
	margin-bottom: 25px;
	padding: 5px;
	color:#000;
	font-size:10px;
	line-height: 18px;
	text-align: center;
	letter-spacing:2px;

添加子节点
由于是便签嘛，所以想着应该需要记录写下便签的时间，所以我们首先，获取时间，然后添加便签的操作使用.append添加子节点就好啦。代码有注释，不懂得可以留言！
index.js

//创建计时器
function Note(){
    var time = new Date();
    y = time.getFullYear();
    mon = time.getMonth()+1;
    d = time.getDate();
    var  h = time.getHours();
    var ampm = h < 12 ? 'AM' : 'PM';
    if(h < 10){
        h = '0' + h;
    }
    else if(h >= 12 && h < 22){
        h = '0' + (h % 12)
    }else if(h >= 22){
        h = h % 12;
    }
    else{
        h = h;
    }

    var  m = time.getMinutes();
    m = m < 10 ? '0'+ m : m;

    var s = time.getUTCSeconds();
    s = s < 10 ? '0'+ s : s;


    var wArr = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];
    w = wArr[time.getDay()];

    //获取元素
    var txt = document.querySelector('#txt');
    var btn = document.querySelector('#add');
    var ul = document.querySelector('.notes');
    var colors =['#ef9a9a','#F48FB1','#CE93D8','#B39DDB','#9FA8DA','#90CAF9','#81D4FA','#80DEEA','#80CBC4','#A5D6A7','#C5E1A5','#FFCC80','#FFAB91','#BCAAA4','#B0BEC5'];
    //注册事件
    btn.onclick = function(){
        txt.focus();
        if(ul.children.length < 8 && txt.value !='' ){

            //创建元素
            var li = document.createElement('li');

            li.style.backgroundColor = colors[parseInt(Math.random()*(colors.length-1))];
            //添加元素
            ul.appendChild(li);
            li.innerHTML = txt.value + "
"+h +":"+ m +" "+ampm+"
" + "+ li.style.backgroundColor +"' >Delete";
            txt.value = '';
            txt.focus();
            //删除元素
            var as = document.querySelectorAll('a');
            for(var i = 0; i < as.length; i++){
                as[i].onclick = function (){
                    ul.removeChild(this.parentNode);
                    txt.focus();
                }
            }

        }else if(ul.children.length == 8){
            txt.value ='';
            txt.setAttribute('placeholder','只能添加8个便签哦！');
            txt.focus();

        }
        else if(txt.value ==''){
            txt.setAttribute('placeholder','请输入内容...');
            txt.focus();
        }
    }
}
//递归调用 每秒调用一次
setInterval("Note()",1000);

var btnn = document.querySelector('#note');
var div = document.querySelector('.btm');
var flag1 = true;
function addFocus(){
    if(!flag1){
        div.style.transform = 'translateX(0px)';
        flag1 = true;
        txt.blur();
    }else{
        div.style.transform = 'translateX(570px)';
        txt.focus();
        flag1 = false;
    }
}
btnn.onclick = function() {
    addFocus();
}

至此我们的便签部分也完成啦！
效果图如下：
