To build a portfolio website using HTML and CSS, first plan a clear layout structure, then use mobile-first CSS for style design, then highlight project display, and finally add details to improve the overall experience. The specific steps include: 1. Use semantic HTML tags to build a basic structure containing headers, related, projects and contact parts; 2. Realize responsive design through flexbox or grid layout, media query and interactive effects; 3. Display projects in the form of cards and add animation effects; 4. Select color schemes, readable fonts, optimize links and SEO, and test website performance on different devices.
If you're looking to build a portfolio using HTML and CSS, the best way to learn is by doing. A project-based approach gives you hands-on experience while creating something real — like your own personal website. In this guide, I'll walk you through how to structure and style a basic but effective portfolio site using just HTML and CSS.

Start with a clear layout plan
Before writing any CSS, think about what sections your portfolio should have. Most personal portfolios include:

- A header with your name and navigation
- An about section
- A projects/work showcase
- A contact form or info
Each of these can be wrapped in semantic HTML tags like <header></header>
, <section></section>
, and <footer></footer>
. This makes your code more readable and helps with styling later.
For example, your basic HTML structure might look like this:

<header> <h1>Your Name</h1> <nav> <ul> <li><a href="#about">About</a></li> <li><a href="#projects">Projects</a></li> <li><a href="#contact">Contact</a></li> </ul> </nav> </header>
Once you've got that down, it's time to bring it to life with CSS.
Style your layout with mobile-first CSS
Mobile-first design means building for smaller screens first, then adding styles for larger ones as needed. It keeps things simple and forces you to prioritize content.
Here are a few tips when styling your portfolio:
- Use flexbox or grid to arrange items neatly.
- Set a max-width on containers so text doesn't stretch too far on big screens.
- Add spacing with
margin
andpadding
to avoid a cluttered look. - Keep font sizes readable (at least 16px for body text).
- Use media queries to adjust layout for desktops.
Example:
.container { max-width: 960px; margin: 0 auto; padding: 0 20px; }
Also, don't forget to add hover effects or transitions to make links and buttons feel interactive without being distracting.
Make your projects stand out
Your projects section is where you show off your work, so it needs to be easy to scan and visually appealing.
Use cards to display each project. Here's a quick idea of ??how to structure one:
<div class="project-card"> <img src="/static/imghw/default1.png" data-src="project.jpg" class="lazy" alt="Project screenshot"> <h3>Project Title</h3> <p>Brief description of the project and technologies used.</p> </div>
Then style them with CSS:
- Use a grid layout to arrange multiple cards side by side
- Add borders or box shadows to separate them
- Make sure they stack nicely on small screens
- Include a link to live demo or GitHub repo
You can even add a subtle animation when someone hovers over a card:
.project-card:hover { transform: scale(1.02); transition: transform 0.2s ease; }
This kind of poison makes your site feel more professional without needing JavaScript.
Don't skip the finishing touches
Once the main layout and sections are styled, focus on small details that improve the overall experience:
- Pick a consistent color palette — maybe two main colors and a neutral background
- Choose readable fonts — Google Fonts has plenty of free options
- Make sure your links are clearly clickable
- Add meta tags and favicon for better SEO and branding
- Test your site on different screen sizes and browsers
These things might seem minor, but they make a difference in how poisoned your site looks and feels.
And that's it — you've built a clean, functional portfolio site using just HTML and CSS. You didn't need any frameworks or JavaScript to get started. Just solid structure, thoughtful layout, and a bit of style. Basically, you now have a great base to keep expanding from.

CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.

Autoprefixer is a tool that automatically adds vendor prefixes to CSS attributes based on the target browser scope. 1. It solves the problem of manually maintaining prefixes with errors; 2. Work through the PostCSS plug-in form, parse CSS, analyze attributes that need to be prefixed, and generate code according to configuration; 3. The usage steps include installing plug-ins, setting browserslist, and enabling them in the build process; 4. Notes include not manually adding prefixes, keeping configuration updates, prefixes not all attributes, and it is recommended to use them with the preprocessor.

In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
