Are you looking to create a simple and professional Tender Portal Website template? Whether you're a student, freelancer, or beginner developer, this tutorial is for you. We will use HTML, Tailwind CSS, and JavaScript to build a responsive and interactive design.

Prerequisites:

Before we begin, make sure you have the following:

  • Basic knowledge of HTML, CSS, and JavaScript
  • Code editor like VS Code
  • Internet connection (for Tailwind CDN)
  • Web browser to test your website

Source Code

Step 1 (HTML Code):

First, we will start with the structure of the website using HTML. This layout will include the header, navigation, and content areas. We will use Tailwind CSS classes in our HTML to make it look clean and professional.

Copy the HTML code below and paste it into your index.html file.

Step 2 (CSS Code):

Even though we are using Tailwind CSS for most of the design, we still need a few custom styles for buttons, cards, tags, or the sidebar. This will give our portal a more polished look.

Copy the CSS code below and paste it into your styles.css file.

Step 3 (JavaScript Code):

Now comes the final step — using JavaScript to make your website interactive. We’ll write a script that shows a list of tenders dynamically.

Copy the JavaScript code below and paste it into your script.js file.
