Number Trivia App using HTML, CSS & JavaScript
Introduction
Hello everyone. Welcome to today’s tutorial on Codewithrandom. We’ll learn how to make Number Trivia App which will an app which consists a trivia and it has random facts & get facts option which tell the facts about the number which has entered by the user. This project will is good for beginners and help them to build their front-end development skills. In Today’s session, We will use HTML, CSS, and JavaScript to complete this Number Trivia App Project.
Project Description
Step 1
The HTML (Hypertext Markup Language) will help us to create the structure for the list with some necessary attributes and elements to make Number Trivia App Project.
Step 2
Then we will use CSS (Cascading Stylesheet) which will help us to style or design the project with suitable padding and alignment in the Number Trivia App Project.
Step 3
At last we will use JS (JavaScript) which will add a logic to make the Number Trivia App Project responsive from the user end.
I hope you have got an idea about the project.
HTML Code for Number Trivia App
First we’ll start with creating the structure of the Number Trivia App project for that as you can see the above code we have used all the necessary elements & attributes to setup the structure. Let us know code the CSS part to add styling and aligned the tags.

Second comes the CSS code in which we have styled for the structure we have padded as well as aligned the Number Trivia App project so that it is properly situated and doesn’t get messy with suitable CSS elements. Now we have created the structure using HTML and styled the webpage using CSS its time to add the functionality using JavaScript in this project.

}10+ Javascript Projects For Beginners With Source Code
JavaScript Code for Number Trivia App
Last stage of the project the JavaScript in which we have added the logical and coded as per the requirement with some conditions. In this code of JavaScript we have defined the buttons which are created in structure in the get element ID and further we have added some functions to make it work on the user side. Let us see the Final Output of the project Number Trivia App using HTML, CSS & JavaScript (Source Code).
let getFactBtn = document.getElementById("get-fact-btn");
let ranFactBtn = document.getElementById("ran-fact-btn");
let fact = document.querySelector(".fact");
let url = "http://numbersapi.com/";
let fetchFact = (num) => {
let finalUrl = url + num;
fetch(finalUrl)
.then((resp) => resp.text())
.then((data) => {
fact.style.display = "block";
fact.innerHTML = `<h2>${num}</h2>
<p>${data}</p>`;
document.querySelector(".container").append(fact);
});
};
let getFact = () => {
let num = document.getElementById("num").value;
//Check if input number is not empty
//If not empty
if (num) {
//Check if number lies between 0 and 300
//if Yes fetch the fact
if (num >= 0 && num <= 300) {
fetchFact(num);
}
//If number is less than 0 or greater than 300 display error message.
else {
fact.style.display = "block";
fact.innerHTML = `<p class="msg"> Please enter a number between 0 to 300.</p>`;
}
}
//If input number is empty display error message
else {
fact.style.display = "block";
fact.innerHTML = `<p class="msg">The input field cannot be empty</p>`;
}
};
let getRandomFact = () => {
//Random number between 0 to 300
let num = Math.floor(Math.random() * 301);
fetchFact(num);
};
getFactBtn.addEventListener("click", getFact);
ranFactBtn.addEventListener("click", getRandomFact);
window.addEventListener("load", getRandomFact);Output
