How can you draw an arrow?

There are several ways:

Using a Unicode character:
```
&rarr; // For example, →
```
Disadvantages: Limited set of characters, issues with scaling and styling.

Using SVG:

<svg width="20" height="20" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round">
  <polyline points="12 5 19 12 12 19"></polyline>
  <line x1="19" y1="12" x2="5" y2="12"></line>
</svg>

Advantages: Scalability, good browser support, styling with CSS.

Using pseudo-elements and CSS Transform:

<div class="arrow-container">
  <span class="arrow"></span>
</div>

.arrow {
  display: inline-block;
  width: 10px;
  height: 10px;
  border-top: 2px solid black;
  border-right: 2px solid black;
  transform: rotate(45deg);
}

Advantages: Clean HTML, flexible styling. Disadvantages: Requires additional CSS rules for positioning and rotation.

Using icon fonts (e.g., Font Awesome):

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.0.0/css/all.min.css">
<i class="fas fa-arrow-right"></i>

Advantages: Wide selection of icons, easy integration. Disadvantages: Requires external library.

The choice of method depends on the specific task and requirements for appearance and functionality of the arrow. For simple cases, Unicode symbols or pseudo-elements are suitable. For more complex or scalable solutions, SVG or icon fonts are better.
