Fundamental Concepts

HTML Structure

HTML provides the basic structure for the gallery. You’ll typically use <div> elements to group images and related elements. The <img> tag is used to display the actual images. For example:

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF - 8">
    <title>Simple Gallery</title>
</head>

<body>
    <div class="gallery">
        <img src="image1.jpg" alt="Image 1">
        <img src="image2.jpg" alt="Image 2">
        <img src="image3.jpg" alt="Image 3">
    </div>
</body>

</html>

CSS Styling

CSS is used to style the gallery. You can control the layout, size, spacing, and appearance of the images. Some important CSS properties for galleries include:

  • display: You can use flexbox or grid to create flexible and responsive layouts. For example, display: flex or display: grid.
  • width and height: To set the size of the images or the gallery container.
  • margin and padding: To add spacing between images and around the gallery.

Usage Methods

Flexbox is a powerful layout model in CSS. To create a simple flexbox gallery:

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF - 8">
    <title>Flexbox Gallery</title>
    <style>
        .gallery {
            display: flex;
            flex-wrap: wrap;
            gap: 10px;
        }

        .gallery img {
            width: 200px;
            height: auto;
        }
    </style>
</head>

<body>
    <div class="gallery">
        <img src="image1.jpg" alt="Image 1">
        <img src="image2.jpg" alt="Image 2">
        <img src="image3.jpg" alt="Image 3">
    </div>
</body>

</html>

In this example, the display: flex property turns the .gallery container into a flex container. The flex-wrap: wrap property allows the images to wrap to the next line if there isn’t enough space. The gap property adds spacing between the images.

Grid is another layout model in CSS that provides more control over the layout. Here’s how to create a grid - based gallery:

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF - 8">
    <title>Grid Gallery</title>
    <style>
        .gallery {
            display: grid;
            grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
            gap: 10px;
        }

        .gallery img {
            width: 100%;
            height: auto;
        }
    </style>
</head>

<body>
    <div class="gallery">
        <img src="image1.jpg" alt="Image 1">
        <img src="image2.jpg" alt="Image 2">
        <img src="image3.jpg" alt="Image 3">
    </div>
</body>

</html>

The display: grid property turns the .gallery container into a grid container. The grid-template-columns property defines the columns of the grid. repeat(auto-fit, minmax(200px, 1fr)) creates columns that are at least 200px wide and will expand to fill the available space.

Common Practices

Image Resizing

It’s important to resize images properly. You can use the width and height properties in CSS to control the size of the images. Also, using max-width: 100% and height: auto ensures that the images scale proportionally and don’t overflow their containers.

Alt Text

Always provide alt text for images. This is important for accessibility, as it helps screen readers describe the images to visually impaired users.

Responsive Design

Make your gallery responsive so that it looks good on different screen sizes. You can use media queries in CSS to adjust the layout based on the screen width. For example:

@media (max - width: 768px) {
    .gallery img {
        width: 100%;
    }
}

Best Practices

Semantic HTML

Use semantic HTML elements whenever possible. Instead of using just <div> elements, you can use <figure> and <figcaption> to group images and their captions. For example:

<figure class="gallery - item">
    <img src="image.jpg" alt="An example image">
    <figcaption>This is a caption for the image</figcaption>
</figure>

Performance Optimization

Optimize your images before using them in the gallery. Compress the images to reduce their file size without sacrificing too much quality. This will improve the loading speed of your website.

Code Organization

Keep your HTML and CSS code organized. Use classes and IDs to target elements and separate your CSS code into external files for better maintainability.

Conclusion

Creating a CSS and HTML - only gallery is a great way to add visual appeal to your website without the need for complex JavaScript. By understanding the fundamental concepts, usage methods, common practices, and best practices, you can build a beautiful and functional gallery. Remember to focus on accessibility, responsiveness, and performance to provide the best user experience.
