How to Build A Dictionary App in HTML CSS & JavaScript.

Build A Dictionary App

Hey friends, I am OMBHUSAL from in today in this blog, you’ll learn How to Build A Dictionary App in HTML CSS & JavaScript. In the earlier blog, I have shared How To Create Responsive Vertical Timeline Design, and now it’s time to create a Dictionary App.

As you all know, what is a dictionary and what does it do? 

In this project (Dictionary App), at first, on the webpage, there is blue background a search input and when you enter any existing word and press enter then there is shown a loading text of “Searching the meaning of your favourite words”.

About the Dictionary App

If the searched word exists then there is shown the meaning, example, synonyms, etc. of the searched word with a slide animation else there is shown a message of “Can’t find the meaning of words”. There is also a pronunciation icon to pronounce your searched word.

Preview of Our Dictionary App

To create this project, there is used API with fetch() method of JavaScript so, if you’re too beginner in JavaScript then it may be difficult to understand you but if you liked this project and want to get source codes or files then you can easily copy or download it from the bottom of this page and learn how it is made.

But before you go to download the codes, let’s understand the JavaScript codes and concepts behind creating this dictionary app. At first, I got the user searched input and then using the fetch API method I sent a get request to an API ( with passing the user searched word.

If the searched word exists then API returns an object of the searched word which holds many details (definition, example, synonyms) of the word else it returns a message of “Can’t find the definitions”. Once I fetched the data from API then I inserted each data into a particular HTML element

I hope you have understood the basic codes behind creating this program. To Build A Dictionary App in HTML CSS & JavaScript, I used HTML CSS and js with the label.

To Build A Dictionary App Follow These Steps:

Step 1

To create this program: (Dictionary App). Initially you need to create two files one HTML (.html) and another CSS file (.css). After creating these files, just paste the following codes into your VS IDE code sample and create an HTML file called index.html and paste the indicated codes into your HTML file (.html) Remember, you must create a file with the extension. HTML.

<!DOCTYPE html>
<!-- Coding By CodeWithNepal - codewithnepal -->
<html lang="en" dir="ltr">
    <meta charset="utf-8">  
    <title>Build A Dictionary App | CodeWithNepal</title>
    <link rel="stylesheet" href="style.css">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <!-- CDN Link for Icons -->
    <link rel="stylesheet" href="">
    <link rel="stylesheet" href=""/>
    <div class="wrapper">
     <header>English Dictionary</header>
      <div class="search">
        <input type="text" placeholder="Search a word" required spellcheck="false">
        <i class="fas fa-search"></i>
        <span class="material-icons">close</span>
      <p class="info-text">Type any existing word and press enter to get meaning, example, synonyms, etc.</p>
        <li class="word">
          <div class="details">
            <span>_ _</span>
          <i class="fas fa-volume-up"></i>
        <div class="content">
          <li class="meaning">
            <div class="details">
          <li class="example">
            <div class="details">
          <li class="synonyms">
            <div class="details">
              <div class="list"></div>

    <script src="script.js"></script>


Step 2

And, create a CSS file named style.css and paste the indicated codes into your CSS file. Remember, you must create a .css file.

Step 3

Last, create a JavaScript file with the name of script.js and paste the given codes into your JavaScript file. Remember, you’ve to create a file with a .js extension.

const wrapper = document.querySelector(".wrapper"),
searchInput = wrapper.querySelector("input"),
volume = wrapper.querySelector(".word i"),
infoText = wrapper.querySelector(".info-text"),
synonyms = wrapper.querySelector(".synonyms .list"),
removeIcon = wrapper.querySelector(".search span");
let audio;

function data(result, word){
        infoText.innerHTML = `Can't find the meaning of <span>"${word}"</span>. Please, try to search for another word.`;
        let definitions = result[0].meanings[0].definitions[0],
        phontetics = `${result[0].meanings[0].partOfSpeech}  /${result[0].phonetics[0].text}/`;
        document.querySelector(".word p").innerText = result[0].word;
        document.querySelector(".word span").innerText = phontetics;
        document.querySelector(".meaning span").innerText = definitions.definition;
        document.querySelector(".example span").innerText = definitions.example;
        audio = new Audio("https:" + result[0].phonetics[0].audio);

        if(definitions.synonyms[0] == undefined){
   = "none";
   = "block";
            synonyms.innerHTML = "";
            for (let i = 0; i < 5; i++) {
                let tag = `<span onclick="search('${definitions.synonyms[i]}')">${definitions.synonyms[i]},</span>`;
                tag = i == 4 ? tag = `<span onclick="search('${definitions.synonyms[i]}')">${definitions.synonyms[4]}</span>` : tag;
                synonyms.insertAdjacentHTML("beforeend", tag);

function search(word){
    searchInput.value = word;

function fetchApi(word){
    wrapper.classList.remove("active"); = "#000";
    infoText.innerHTML = `Searching the meaning of <span>"${word}"</span>`;
    let url = `${word}`;
    fetch(url).then(response => response.json()).then(result => data(result, word)).catch(() =>{
        infoText.innerHTML = `Can't find the meaning of <span>"${word}"</span>. Please, try to search for another word.`;

searchInput.addEventListener("keyup", e =>{
    let word =\s+/g, ' ');
    if(e.key == "Enter" && word){

volume.addEventListener("click", ()=>{ = "#4D59FB";;
    setTimeout(() =>{ = "#999";
    }, 800);

removeIcon.addEventListener("click", ()=>{
    searchInput.value = "";
    wrapper.classList.remove("active"); = "#9A9A9A";
    infoText.innerHTML = "Type any existing word and press enter to get meaning, example, synonyms, etc.";

Outro of Dictionary App

That’s all, now you’ve successfully built an English Dictionary App in HTML CSS & JavaScript. If your code doesn’t work or you’ve faced any error/problem, you can contact me through the contact page.

This project is based on API but you don’t need to signup anywhere and pass the API key to use this dictionary app. I have used the free API ( for this project and to use this API there is no need for signup or API key.
