Amazing New Tab Focus Page With JavaScript

Hi guys, in this post I'll show to you a simple page inspired who I recreated inspired in this youtube video:
https://youtu.be/fSTQzlprGLI (go there and watch if you want to learn JavaScript, it's good for beginners like me).

Ok, in parts!

First, we need to create a HTML template:

<div id="box">
    <time id="time"></time>
    <h1>
        <span id="good"></span>
        <span id="name"></span>
    </h1>
    <h2 id="phrase">Your focus?</h2>
    <h2 id="coolThing" contenteditable="true"></h2>
</div>

Now, we go to CSS:

* {
    box-sizing: border-box;
    margin: 0;
    padding: 0;
}

body {
    font-family: 'Quicksand', sans-serif;    
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
    color: black;
    height: 100vh;
    background-size: auto;
    background-position: center;
    background-repeat: no-repeat;
    background-size: cover;
}

#box {
    background: rgba(255, 255, 255, 0.1);
    justify-content: center;
    align-items: center;
    flex-direction: column;
    text-align: center;
    background-size: auto;
    width: 480px;
    height: 330px;
}

#time {
    font-size: 8rem;
}

h1 {
    margin-bottom: 3rem;
}

h2 {
    margin-bottom: 0.5rem;
    opacity: 0.5;
}

#coolThing {
    text-decoration: underline;
}

@media(max-width: 700px){
    #time {
        font-size: 6rem;
    }
}

And the last we go to the JavaScript code in parts. We need to get the DOM Elements:

var time = document.getElementById('time');
var good = document.getElementById('good');
var phrase = document.getElementById('phrase');
var coolThing = document.getElementById('coolThing');

Setting the clock function, using a construtor so we need to use the word 'new' before to create a construtor to get the hours, minutes and seconds. Using the .innerHTML to put this in the HTML page and the function setTimeout to create a cronometer. The theZero function add the 0 in the hours/minutes or seconds between 1 and 9:

function clock(){
    let clockTime = new Date();
    let hour = theZero(clockTime.getHours());
    let min = theZero(clockTime.getMinutes());
    let sec = theZero(clockTime.getSeconds());

    time.innerHTML = `${hour}:${min}:${sec}`;

    setTimeout(clock, 1000);
}

function theZero(number){
    return (parseInt(number, 10) < 10 ? '0' : '') + number;
}

The function 'askTheName' get the name with prompt and use 'localStorage' to get the name recorded in the storage to don't show again the prompt.

function askTheName(){
    let theName = localStorage.getItem('theName');
    let name = document.getElementById('name');
    if(!theName){
        theName = prompt('Enter your name:');
    }
    if(theName != null){
        localStorage.setItem('theName', theName);
        document.title = 'Keep in Focus ' + theName + '!';
        name.textContent = theName;
    }
}

And now, we create a function 'bgAndPhrase' to setting the conditions to show the phrase "Good Morning, Afternoon or Evening" according the background image (the images we get from the Unsplash):

function bgAndPhrase(){
    let today = new Date();
    hour = today.getHours();
    if(hour < 12){
        good.textContent = 'Good Morning';
        document.body.style.backgroundImage = "url('https://source.unsplash.com/random/1024x720/?morning,sunrise')";
    } else if(hour < 18){
        good.textContent = 'Good Afternoon';
        document.body.style.backgroundImage = "url('https://source.unsplash.com/random/1024x720/?afternoon,golden+hour')";
    } else{
        good.textContent = 'Good Evening';
        document.body.style.backgroundImage = "url('https://source.unsplash.com/random/1024x720/?evening,night')";
    }
}

Now, we just need call the functions:

askTheName();
clock();
bgAndPhrase();

Enjoy!
