Little Flashback

Hashnode being the best place for developer blogging introduced Custom CSS last year. I'm inspired by how useful it will be in real life. Its what No other blogging platforms could offer and makes hashnode unique. Thant made me think 🤔

✨️ Inspiration

Hashnode brought Custom CSS feature and soon it became trending. People started playing with it and they enjoyed it. I joined hashnode in the end of 2020, and found Custom CSS is super cool. Indeed, I started playing with it and just loved it.

And I created a Custom CSS for my blog too. Readers started enjoying it. Its not that easy to create Custom CSS. These are the steps needed for it.

  1. Inspect your page and find class names.
  2. There is no live preview. We have to reload and reload.
  3. Adjust brower size for different media (phone, tablet, laptop) is a mess.
  4. Handling Dark Mode is hard.
  5. It take a lot of time for this process.

So, that's the exact reason why I built Styler. Auth0 Hackathon was the push 🔥


I have created a short demo video in which I create a super cool Custom CSS code from scratch. (~2 mins), use headphones 🎧

Now, let me show you the amazing features Styler have so far ✌️

  • Live Preview

🛠️ Planning, Building, and Deploying

This idea was revolving around my head since the hackathon was announced. I did some preparation before touching the code. I reached out to hashnode team and got connected with them, as I'm gonna work a lot with scraping for a demo blog, I thought it was very necessary. I learned how to scrape it and transform the raw HTML to a productive preice of JS.

I fetched the resources I'd need for it and did a pretty good plan of which how I'd go further. Also, I learned new modules and libraries. Yeah, you can read more of my plans and struggles here 👇

  • Planning

    You know already, everyone prefer notion to plan. I created a checklist and some tables of which how I'd go further. I do believe a good plan is very much important for a good project.

  • Designing

    I didn't used my all time favourite tool Figma much for this. Its just because I already have a design for UI in my mind and I just went on. I'm glad I did well.

  • Building

    The time consuming part arrived. xD It all started by creating a next app.

    npx create-next-app -e with-tailwindcss styler

    I'm a big fan of tailwind CSS, recently loving it a lot. I'm sticking to it for this project too. I have heard a lot about Auth0, but never got a chance to check it out. Gladly, I checked it and loved it. Its super awesome and super fast. Here is how I connected my Next JS app with Auth0.

    First I installed Auth0 for next js module.

    npm i @auth0/nextjs-auth0

    Then its pretty easy, first import UserProvider wrapper from Auth0 in out _app.js page.

    import { UserProvider } from "@auth0/nextjs-auth0";

    After importing, we just have to wrap it around our component like this 👇

        <Component {...props} />

    Now, we need to create a folder auth inside the api folder of pages. Inisde auth folder, we should create a new file [...auth0].js and add the following code 👇

    import { handleAuth } from "@auth0/nextjs-auth0";
    export default handleAuth();

    Now, you need to fill your .env with the things you got from your Auth0 dashboard.


    Wohoo!! You're done, a user can login by going to localhost:3000/api/auth/login or logout by localhost:3000/api/auth/logout. How fast was that?

    Just create a Sign In button with href to localhost:3000/api/auth/login to start playing with your users. I'm pretty impressed by how fast it is and I feel like I should knew this earlier. This is super cool.

    Now, let me show you some other quick snippets I used. Here is the one I used to created the Fit to Window feel.

    const resizeCoverImage = () => {
      const iframe = document.querySelector("#iframe");
      const container = document.querySelector(".playground");
      const maxWidth = iframe.offsetWidth;
      const maxHeight = iframe.offsetHeight;
      const width = container.offsetWidth;
      const height = container.offsetHeight;
      let scale; // scale to be used
      if (width >= maxWidth && height >= maxHeight) {
 = "";
      scale = Math.min(width / maxWidth, height / maxHeight); // trick to get scale
  = `scale(${scale})`; // transform scale applied

    Here the snippet I used to handle the onclick inside the iframe. This was new to me.

    useEffect(() => {
      let iframe = document.getElementById("iframe").contentWindow.document;
      if (iframe) {
          iframe.body.onclick = function(e) {
              // do stuff

    If you're wondering how Am I changing the look and feel on the iframe. Here it is how 👇

    useEffect(() => {
      let style = document
          .contentWindow.document.getElementById("style"); // get style element with id from Iframe
      if (style) {
          style.innerHTML = CSSCode; // set inerHtml for style element
    }, [CSSCode]);

    The whole build process is far longer, So, I'm stopping here. Checkout Styler on Github, to learn more on these stuffs.

  • Deploying

    As usual, I decided to stick with my all-time favorite Vercel, I pretty much use it to host all my apps. In fact Next JS is best to host with Vercel.

🌈 What's next

Styler is the most hardest project I have ever made. I have ruined 2 full days to fix a 1 line bug for it. Still, I'm happy that I could complete Styler by the best. Here is the roadmap of the future of Styler 🤞

  • history of previous codes
  • Share preview URLs
  • Live Collaborate with partner
  • More Templates
  • Better Position Tracker
  • Change the default preview page with users own page

The best way to test Styler is to test on my blog itself right? Yes, I have used Styler to create this UI you're seeing right now. You liked it right?

Hashnode prefers to only write CSS for the standard classes. I have done a bit more things my blog. You can also do it on Styler. Here are all the standard classes
