### JavaScript for PicoCSS UI Interactions and Theme Switching

Source: https://github.com/yohn/picocss/blob/main/docs/index.html

This JavaScript code executes on DOMContentLoaded, handling various UI interactions. It initializes a `FileValidator`, manages alignment classes for a row based on button clicks, highlights code blocks using `hljs.highlightElement`, and provides a `changeTheme` function to dynamically update the PicoCSS theme via a CDN link, triggered by elements with the `change-theme` class. It also initializes `PicoTabs`.

```JavaScript
document.addEventListener("DOMContentLoaded", () => { const checkFile = document.getElementById("checkFile"); new FileValidator(checkFile); const alignButtons = document.querySelectorAll(".change-row-align"); const alignRow = document.getElementById("row-align-example"); alignButtons.forEach((button) => {
 button.addEventListener("click", () => {
 let dir = button.getAttribute('data-align');
 console.log(dir)
 if (dir == 'start') {
 alignRow.classList.remove('align-center', 'align-end');
 alignRow.classList.add('align-start');
 } else if (dir == 'center') {
 alignRow.classList.remove('align-start', 'align-end');
 alignRow.classList.add('align-center');
 } else {
 alignRow.classList.remove('align-start', 'align-center');
 alignRow.classList.add('align-end');
 }
 });
 });
 document.querySelectorAll('pre code').forEach((el) => { hljs.highlightElement(el); });
 // Function to change the theme
 function changeTheme(newTheme) {
 const linkElement = document.getElementById('theme-color-ss');
 if (linkElement) {
 linkElement.setAttribute('href', 'https://cdn.jsdelivr.net/gh/Yohn/PicoCSS@2.2.10/css/pico.' + newTheme + '.min.css');
 }
 }
 // Adding click event listener to all elements with the "change-theme" class
 document.querySelectorAll('.change-theme').forEach(element => {
 element.addEventListener('click', function () {
 const newTheme = this.getAttribute('data-theme');
 changeTheme(newTheme);
 });
 });
 new PicoTabs('\\[role=\"tablist\\]');
 });
```

### Responsive Grid Layout Classes

Source: https://github.com/yohn/picocss/blob/main/docs/index.html

Pico.css provides a responsive grid system with `.col-*`, `.col-*BREAKPOINT*-*`, and `.offset-*` classes for defining columns and offsets. `.row` has a max width, while `.row-fluid` is 100% width. Alignment classes like `.align-start`, `.align-center`, or `.align-end` can be added to `.row` or `.row-fluid`.

```HTML
<!-- Basic Columns -->
<div class="row">
  <div class="col-3"></div>
  <div class="col-6"></div>
  <div class="col-3"></div>
</div>

<!-- Columns with Offsets -->
<div class="row">
  <div class="col-3 offset-1"></div>
  <div class="col-2"></div>
  <div class="col-2"></div>
</div>

<!-- Responsive Columns with Breakpoints -->
<div class="row">
  <div class="col-2 col-md-4"></div>
  <div class="col-4 offset-8 col-md-6 offset-md-6"></div>
  <div class="col-5 offset-1 col-md-11"></div>
  <div class="col-2 col-md-6"></div>
  <div class="col-3 offset-9 col-md-6 offset-md-6"></div>
  <div class="col-3 col-md-12 col-lg-6"></div>
  <div class="col-3 col-md-12 col-lg-6"></div>
  <div class="col-4 col-md-6 col-lg-3"></div>
  <div class="col-6 offset-6 col-md-3 offset-md-9 col-lg-2 offset-lg-10"></div>
</div>

<!-- Alignment Classes -->
<div class="row align-center">
  <div class="col-4"></div>
  <div class="col-4"></div>
</div>

<!-- Medium Breakpoint Example -->
<div class="row">
  <div class="col-12 col-md-4"></div>
