This article continues the exploration of creating visually striking image galleries using CSS Grid, clipping, and masking techniques. Building on previous installments, we'll delve into more intricate shape designs. As before, the focus remains on achieving complex layouts with minimal HTML.
CSS Grid and Custom Shapes Series Recap
- Part 1
- Part 2
- Part 3 (Current Article)
Prior Article Reading: While not strictly necessary, prior articles are highly recommended to grasp the full range of techniques. However, each article can be understood independently.
Let's begin with our first example.
Die-Cut Photo Gallery
The HTML remains simple:
<div class="gallery"> <img src="/static/imghw/default1.png" data-src="https://img.php.cn/" class="lazy" alt="CSS Grid and Custom Shapes, Part 3 "><img src="/static/imghw/default1.png" data-src="https://img.php.cn/" class="lazy" alt="CSS Grid and Custom Shapes, Part 3 "><img src="/static/imghw/default1.png" data-src="https://img.php.cn/" class="lazy" alt="CSS Grid and Custom Shapes, Part 3 "><img src="/static/imghw/default1.png" data-src="https://img.php.cn/" class="lazy" alt="CSS Grid and Custom Shapes, Part 3 "> </div>
The core challenge is to leverage CSS to create the visual design. The CSS uses a square grid with three columns, strategically positioning images to create overlaps:
.gallery {
--g: 6px; /* Gap between images */
display: grid;
width: 450px;
aspect-ratio: 1; /* Square grid */
grid: auto-flow 1fr / repeat(3, 1fr);
gap: var(--g);
}
.gallery img:nth-child(2) {
grid-area: 1 / 2 / span 2 / span 2;
}
.gallery img:nth-child(3) {
grid-area: 2 / 1 / span 2 / span 2;
}
The grid shorthand property efficiently defines the grid layout. The second and third images are explicitly positioned, allowing the others to auto-place. clip-path is then used to create the die-cut effect on the overlapping images:
.gallery img:nth-child(2) {
/* ... other styles ... */
clip-path: polygon(0 0, 100% 0, 100% 100%, calc(50% + var(--g) / 4) 100%, 0 calc(50% - var(--g) / 4));
}
.gallery img:nth-child(3) {
/* ... other styles ... */
clip-path: polygon(0 0, calc(50% - var(--g) / 4) 0, 100% calc(50% + var(--g) / 4), 100% 100%, 0 100%);
}
A grayscale hover effect enhances the visual appeal.
Split Image Reveal
This example demonstrates an image reveal effect on hover. Two overlapping images are used:
.gallery {
display: grid;
}
.gallery > img {
grid-area: 1 / 1;
width: 350px;
aspect-ratio: 1;
}
The clip-path animation creates the reveal effect. Three states are defined: no hover, hover on the first image, and hover on the second image. The clip-path uses three-point polygons, leveraging the concept of "overflowing" shapes to simplify the CSS. A transition is applied to smoothly animate the clip-path changes on hover.
Pie Image Reveal
This example extends the reveal effect to four images arranged in a pie-like layout. The clip-path animation creates the illusion of a quarter-circle expanding into a full circle on hover. The effect is achieved through carefully crafted seven-point polygons and rapid animation.
Mosaic of Images
This section explores creating a mosaic effect from multiple overlapping images. The grid layout is carefully determined by analyzing the image arrangement, resulting in a 2x4 grid. clip-path is used to shape individual images to fit the mosaic.
Complex Mosaic of Images
This final example showcases a more complex, asymmetrical mosaic. The process of determining the grid layout and clip-path values is detailed, demonstrating a systematic approach to creating intricate designs. Optimization techniques are employed to reduce the number of clip-path declarations.
Conclusion
This series showcases the power of CSS Grid and clip-path for creating sophisticated image gallery layouts with minimal HTML. The examples demonstrate various techniques and approaches, encouraging readers to experiment and create their own unique designs. The article concludes with a challenge for readers to create their own mosaics using the techniques learned.

CSS tutorial for creating loading spinners and animations
Jul 07, 2025 am 12:07 AM
There are three ways to create a CSS loading rotator: 1. Use the basic rotator of borders to achieve simple animation through HTML and CSS; 2. Use a custom rotator of multiple points to achieve the jump effect through different delay times; 3. Add a rotator in the button and switch classes through JavaScript to display the loading status. Each approach emphasizes the importance of design details such as color, size, accessibility and performance optimization to enhance the user experience.
Addressing CSS Browser Compatibility issues and prefixes
Jul 07, 2025 am 01:44 AM
To deal with CSS browser compatibility and prefix issues, you need to understand the differences in browser support and use vendor prefixes reasonably. 1. Understand common problems such as Flexbox and Grid support, position:sticky invalid, and animation performance is different; 2. Check CanIuse confirmation feature support status; 3. Correctly use -webkit-, -moz-, -ms-, -o- and other manufacturer prefixes; 4. It is recommended to use Autoprefixer to automatically add prefixes; 5. Install PostCSS and configure browserslist to specify the target browser; 6. Automatically handle compatibility during construction; 7. Modernizr detection features can be used for old projects; 8. No need to pursue consistency of all browsers,

Creating custom shapes with css clip-path
Jul 09, 2025 am 01:29 AM
Use the clip-path attribute of CSS to crop elements into custom shapes, such as triangles, circular notches, polygons, etc., without relying on pictures or SVGs. Its advantages include: 1. Supports a variety of basic shapes such as circle, ellipse, polygon, etc.; 2. Responsive adjustment and adaptable to mobile terminals; 3. Easy to animation, and can be combined with hover or JavaScript to achieve dynamic effects; 4. It does not affect the layout flow, and only crops the display area. Common usages are such as circular clip-path:circle (50pxatcenter) and triangle clip-path:polygon (50%0%, 100 0%, 0 0%). Notice
Styling visited links differently with CSS
Jul 11, 2025 am 03:26 AM
Setting the style of links you have visited can improve the user experience, especially in content-intensive websites to help users navigate better. 1. Use CSS's: visited pseudo-class to define the style of the visited link, such as color changes; 2. Note that the browser only allows modification of some attributes due to privacy restrictions; 3. The color selection should be coordinated with the overall style to avoid abruptness; 4. The mobile terminal may not display this effect, and it is recommended to combine it with other visual prompts such as icon auxiliary logos.
How to create responsive images using CSS?
Jul 15, 2025 am 01:10 AM
To create responsive images using CSS, it can be mainly achieved through the following methods: 1. Use max-width:100% and height:auto to allow the image to adapt to the container width while maintaining the proportion; 2. Use HTML's srcset and sizes attributes to intelligently load the image sources adapted to different screens; 3. Use object-fit and object-position to control image cropping and focus display. Together, these methods ensure that the images are presented clearly and beautifully on different devices.
Demystifying CSS Units: px, em, rem, vw, vh comparisons
Jul 08, 2025 am 02:16 AM
The choice of CSS units depends on design requirements and responsive requirements. 1.px is used for fixed size, suitable for precise control but lack of elasticity; 2.em is a relative unit, which is easily caused by the influence of the parent element, while rem is more stable based on the root element and is suitable for global scaling; 3.vw/vh is based on the viewport size, suitable for responsive design, but attention should be paid to the performance under extreme screens; 4. When choosing, it should be determined based on whether responsive adjustments, element hierarchy relationships and viewport dependence. Reasonable use can improve layout flexibility and maintenance.
What are common CSS browser inconsistencies?
Jul 26, 2025 am 07:04 AM
Different browsers have differences in CSS parsing, resulting in inconsistent display effects, mainly including the default style difference, box model calculation method, Flexbox and Grid layout support level, and inconsistent behavior of certain CSS attributes. 1. The default style processing is inconsistent. The solution is to use CSSReset or Normalize.css to unify the initial style; 2. The box model calculation method of the old version of IE is different. It is recommended to use box-sizing:border-box in a unified manner; 3. Flexbox and Grid perform differently in edge cases or in old versions. More tests and use Autoprefixer; 4. Some CSS attribute behaviors are inconsistent. CanIuse must be consulted and downgraded.
