A showcase of Simple.css formatting in action and how to use it.

This page is a demonstration of the elements that can be formatted using Simple.css. Each section includes a code block on how to include it in your site’s design.

This may be a little basic for some people, but I wanted to barrier for entry to be as low as possible for this project.

Basic Typography

All the typography of Simple.css uses rem for sizing. This means that accessibility is maintained for those who change their browser font size. The body element has a size of 1.15rem which makes all the standard font sizes slightly larger. This equates to 18.4px for paragraph text, instead of the standard 16px.

The heading elements also have an increased top margin in order to break blocks of text up better.

Heading 1 2.8rem

Heading 2 2.25rem

Heading 3 1.8rem

Heading 4 1.44rem

Heading 5 1.15rem
Heading 6 .92rem
<h2>This is a H2 header<h2>

<p>This is some paragraph text.</p>

Links are formatted very simply on Simple.css (shock horror). They use the accent CSS variable and are underlined. There is a :hover effect that removes the underline. Here is an example link.

Buttons use the same accent CSS variable for their colour. When hovering, there is an opacity effect.

<a href="">This is a hyperlink</a>

<button>I'm a button</button>

Other typography elements

There are a number of other typography elements that you can use with Simple.css. Some of the common ones are:

<b>Bold text</b>
<i>Italic text</i>
<u>Underlined text</u>
<mark>Highlighted text</mark>
<code>Inline code</code>


We all love a good list, right? I know my wife does!

  1. Do this thing
  2. Do that thing
  3. Do the other thing
# Bulleted list
  <li>Item 1</li>
  <li>Item 2</li>
  <li>Item 3</li>

# Numbered list
  <li>Do this thing</li>
  <li>Do that thing</li>
  <li>Do the other thing</li>


Sometimes you may want to quote someone else in your HTML. For this we use the blockquote element. Here’s what a quote looks like with Simple.css:

Friends don’t spy; true friendship is about privacy, too.

– Stephen King

  <p>Friends don’t spy; true friendship is about privacy, too.</p>
  <p><cite>– Stephen King</cite></p>

Code blocks

Code blocks are different from the inline code element. Code blocks are used when you want to display a block of code, like this:

body {
  color: var(--text);
  background: var(--bg);
  font-size: 1.15rem;
  line-height: 1.5;
  margin: 0;
  body {
    color: var(--text);
    background: var(--bg);
    font-size: 1.15rem;
    line-height: 1.5;
    margin: 0;

The nav menu is deliberately designed to be extremely simple so that you can improve on it as you see fit. Or, just leave it as is to have a good looking, functional navigation menu.

There’s no JavaScript of checkbox CSS hacks here. It’s just a collection of simple “buttons” that wrap to the given width of the page:

To add a nav menu, just add the following to the <header> section of your site:

  <a href="">Home</a>
  <a href="">About</a>
  <a href="">Blog</a>
  <a href="">Notes</a>
  <a href="">Guestbook</a>
  <a href="">Contact</a>


In Simple.css, images within the main element are always full width and have rounded edges to them. The figcaption element is also formatted in Simple.css. Here are examples of images with and without a caption:

A dog at an iPad

This is a goose (I think)
This is a goose (I think)


Accordions are cool to play with. They’re especially useful when it comes to things like FAQ pages. Many people invoke JavaScript, or div for life when they use accordions. I don’t really understand why that is what it’s available in plain old HTML:

Spoiler alert!

You smell. 🙂

  <summary>Spoiler alert!</summary>
  <p>You smell. 🙂</p>


Like lists, sometimes you may need to add a table to your webpage. In Simple.css tables automatically highlight every other row to make reading easier. Table header text is also bold. Here’s what they look like:

Name Number
Jackie 012345
Lucy 112346
David 493029
Kerry 395499
Steve 002458


Forms are useful for all kinds of things on webpages. Contact forms, newsletter sign ups etc. Forms also look pretty good on Simple.css:

This is just a test form. It doesn't do anything.

  <p><strong>This is just a test form. It doesn't do anything.</strong></p>  
    <label>First name</label><br>  
    <input type="text" name="first_name">  
    <input type="text" name="surname">  
    <input type="email" name="email" required="">  
    <input type="checkbox" value="terms">  
    I agree to the <a href="#">terms and conditions</a>  
  <button type="reset">Reset</button>  
  <button disabled="disabled">Disabled</button>
