Blog Comment Section Design

This HTML, CSS, and JavaScript code snippet helps you to design the comment section on your blog/website.  It comes with user avatars, names, timestamps, comments, and like buttons. Users can like comments, and the code handles updating like counts when a like button is clicked. It’s helpful for adding a user-friendly comment section to a website.

How to Create Blog Comment Section Design

1. First, create an HTML structure for your comment section. In the provided code, we have used a main element and a section with the class comment-module to contain our comments.

<main>
        <section class="comment-module">
            <ul>
                <li>
                    <div class="comment">
                        <div class="comment-img">
                            <img src="https://rvs-comment-module.vercel.app/Assets/User Avatar.png" alt="">
                        </div>
                        <div class="comment-content">
                            <div class="comment-details">
                                <h4 class="comment-name">Adamsdavid</h4>
                                <span class="comment-log">20 hours ago</span>

                            <div class="comment-desc">

Inside the section element, you can add individual comments as list items (<li>) with user avatars, names, timestamps, comments, and like buttons.

2. The CSS code is responsible for styling the comment section. It sets the overall layout, styles the avatars, and positions the various elements. It also makes the comment section responsive.

You can include this CSS in a separate file or within a <style> block in your HTML file. Make sure to link to the required fonts from Google Fonts.

3. The JavaScript code handles the like functionality for each comment. It collects all the like buttons and adds event listeners to them. When a like button is clicked, it updates the like count for that comment.

let likesUpParent = document.getElementsByClassName("comment-likes-up");
let likesDownParent = document.getElementsByClassName("comment-likes-down");

let likesEl = [];
for(let i = 0; i<likesUpParent.length; i++) {
    let likesUp = likesUpParent[i].getElementsByTagName("img")[0];
    let likesDown = likesDownParent[i].getElementsByTagName("img")[0];

    likesEl.push(likesUp, likesDown);
}

likesEl.forEach(el => {
    el.addEventListener("click", function() {
        let likesClosestCountEl = this.parentElement.getElementsByTagName("span")[0];
        let likesCount = likesClosestCountEl.innerText;

        if(likesCount.trim().length === 0) {
            let likesCount = 0;
        }

        likesClosestCountEl.innerText = +likesCount + +1;

    })
})
