write a beautiful search input and Clear content using js full code

Here's an example of a beautiful search input with clear content button using JavaScript:

HTML:

<div class="search-container">
  <input type="text" id="search-input" placeholder="Search...">
  <button id="clear-button" aria-label="Clear search input">
    <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24">
      <path d="M12 2C6.5 2 2 6.5 2 12s4.5 10 10 10 10-4.5 10-10S17.5 2 12 2zm4.2 15.8l-1.4 1.4L12 13.4l-2.8 2.8-1.4-1.4L10.6 12 7.8 9.2l1.4-1.4L12 10.6l2.8-2.8 1.4 1.4L13.4 12l2.8 2.8z"/>
    </svg>
  </button>
</div>

CSS:

.search-container {
  position: relative;
}

#search-input {
  width: 100%;
  padding: 12px 16px;
  border: none;
  border-radius: 20px;
  background-color: #f2f2f2;
  font-size: 16px;
  color: #333;
  outline: none;
}

#search-input:focus {
  background-color: #fff;
  box-shadow: 0 0 0 2px #007bff;
}

#clear-button {
  position: absolute;
  top: 50%;
  right: 16px;
  transform: translateY(-50%);
  background: none;
  border: none;
  cursor: pointer;
  outline: none;
  opacity: 0.5;
  transition: opacity 0.2s ease-in-out;
}

#clear-button:hover {
  opacity: 1;
}

#clear-button svg {
  width: 24px;
  height: 24px;
  fill: #333;
}

JavaScript:

const searchInput = document.getElementById('search-input');
const clearButton = document.getElementById('clear-button');

searchInput.addEventListener('input', () => {
  clearButton.style.display = searchInput.value !== '' ? 'block' : 'none';
});

clearButton.addEventListener('click', () => {
  searchInput.value = '';
  searchInput.focus();
  clearButton.style.display = 'none';
});

In this example, the search input has a rounded border and a gray background. When the user types in the search input, a clear button appears on the right side of the input. The clear button is hidden by default and only appears when the search input has a value. When the user clicks the clear button, the search input is cleared and the focus is returned to the input.
