V. Examples

A. Simple examples demonstrating vertical-align

Below are some simple examples showcasing the vertical-align property:

<style>
    .container {
        border: 1px solid #000;
        height: 100px;
        text-align: center;
    }
    .inline-block {
        display: inline-block;
        vertical-align: middle;
    }
</style>

<div class="container">
    <span class="inline-block">Aligned Middle</span>
    <span class="inline-block">Example Text</span>
</div>

In this example, the text within the container is aligned vertically in the middle, showcasing the effect of the vertical-align property.

B. Practical applications in web design

Vertical alignment is crucial in various web design scenarios, such as:

• Aligning text within buttons for better user experience.
• Centering images alongside text in galleries or content sections.
• Positioning elements in navigation bars for a polished look.

<style>
    .button {
        display: inline-block;
        padding: 10px 20px;
        background-color: #007bff;
        color: white;
        border: none;
        text-align: center;
        vertical-align: middle;
        line-height: 40px; /* Center text vertically */
    }
</style>

<button class="button">Click Me!</button>

In this case, the button text is centrally aligned vertically, providing an attractive and functional design.
