Are you looking to create a professional and modern cyber security website? Whether you're starting a new tech service or want to practice web design, creating a cyber security website template using HTML and CSS is a great project.

In this guide, we’ll walk you through the steps to build your own simple, responsive template. No frameworks needed. Just basic HTML and CSS — perfect for beginners and developers who want a clean and effective design.

Prerequisites

Before we start, make sure you have the following:

  • A code editor like VS Code
  • Basic knowledge of HTML and CSS
  • A web browser to preview your page

Source Code

Step 1 (HTML Code):

First, we’ll begin with HTML, which builds the basic structure of your cyber security website. Think of it as the skeleton of your page.

Create a file called index.html and paste the following code into it. This will set up the layout, including the header, hero section, and footer.

Step 2 (CSS Code):

After finishing the HTML structure, let’s move to CSS. This part is all about design, colors, layout, and making your website look clean and modern.

Create a new file called style.css and paste the following code inside it:

@import url('https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600;700&display=swap');
@import url('https://fonts.googleapis.com/css2?family=JetBrains+Mono:wght@400;500&display=swap');
