# Icon

[component-header:sl-icon]

Icons are symbols that can be used to represent various options within an application.

Shoelace comes bundled with over 1,100 icons courtesy of the [Bootstrap Icons](https://icons.getbootstrap.com/) project. If you prefer, you can also register [custom icon libraries](/components/icon-library.md).

Click or tap on an icon below to copy its name and use it like this.

```html
<sl-icon name="icon-name-here"></sl-icon>
```

<div class="icon-search">
  <div class="icon-search-controls">
    <sl-input placeholder="Search Icons" clearable>
      <sl-icon slot="prefix" name="search"></sl-icon>
    </sl-input>
    <sl-select value="outline">
      <sl-menu-item value="outline">Outlined</sl-menu-item>
      <sl-menu-item value="fill">Filled</sl-menu-item>
      <sl-menu-item value="all">All icons</sl-menu-item>
    </sl-select>
  </div>
  <div class="icon-list"></div>
  <input type="text" class="icon-copy-input">
</div>

## Examples

### Sizing

Icons are sized relative to the current font size. To change their size, set the `font-size` property on the icon itself or on a parent element as shown below.

```html preview
<div style="font-size: 32px;">
  <sl-icon name="exclamation-triangle"></sl-icon>
  <sl-icon name="archive"></sl-icon>
  <sl-icon name="battery-charging"></sl-icon>
  <sl-icon name="bell"></sl-icon>
  <sl-icon name="clock"></sl-icon>
  <sl-icon name="download"></sl-icon>
  <sl-icon name="file-earmark"></sl-icon>
  <sl-icon name="flag"></sl-icon>
  <sl-icon name="heart"></sl-icon>
  <sl-icon name="image"></sl-icon>
  <sl-icon name="lightning"></sl-icon>
  <sl-icon name="mic"></sl-icon>
  <sl-icon name="search"></sl-icon>
  <sl-icon name="star"></sl-icon>
  <sl-icon name="trash"></sl-icon>
  <sl-icon name="x-circle"></sl-icon>
</div>
```

### Custom Icons

Custom icons can be loaded individually with the `src` attribute. Only SVGs on a local or CORS-enabled endpoint are supported. If you're using more than one custom icon, it might make sense to register a [custom icon library](/components/icon-library.md).

```html preview
<sl-icon src="/assets/images/shoe.svg" style="font-size: 8rem;"></sl-icon>
```

<!-- Supporting scripts and styles for the search utility -->
<script>
  fetch('/dist/shoelace/icons/icons.json')
    .then(res => res.json())  
    .then(icons => {
      const container = document.querySelector('.icon-search');
      const input = container.querySelector('sl-input');
      const select = container.querySelector('sl-select');
      const copyInput = container.querySelector('.icon-copy-input');
      const loader = container.querySelector('.icon-loader');
      const list = container.querySelector('.icon-list');
      const queue = [];

      // Generate icons
      icons.map(i => {
        const item = document.createElement('div');
        item.classList.add('icon-list-item');
        item.setAttribute('data-name', i.name);
        item.setAttribute('data-terms', [i.name, i.title, ...(i.tags || []), ...(i.categories || [])].join(' '));
        item.innerHTML = `
          <svg width="1em" height="1em">
            <use xlink:href="/assets/icons/sprite.svg#${i.name}"></use>
          </svg>      
        `;

        const tooltip = document.createElement('sl-tooltip');
        tooltip.content = i.name;
        
        tooltip.appendChild(item);
        list.appendChild(tooltip);

        item.addEventListener('click', () => {
          copyInput.value = i.name;
          copyInput.select();
          document.execCommand('copy');
          tooltip.content = 'Copied!';
          setTimeout(() => tooltip.content = i.name, 1000);
        });
      });

      // Filter as the user types
      input.addEventListener('slInput', () => {
        [...list.querySelectorAll('.icon-list-item')].map(item => {
          const filter = input.value.toLowerCase();
          if (filter === '') {
            item.hidden = false;
          } else {
            const terms = item.getAttribute('data-terms').toLowerCase();
            item.hidden = terms.indexOf(filter) < 0;
          }
        });
      });

      // Sort by type and remember preference
      const iconType = localStorage.getItem('sl-icon:type') || 'outline';
      select.value = iconType;
      list.setAttribute('data-type', select.value);
      select.addEventListener('slChange', () => {
        list.setAttribute('data-type', select.value);
        localStorage.setItem('sl-icon:type', select.value);
      });
    });
