Quick Reference
The image-rendering property specifies the type of algorithm to be used for image scaling, and has no effect on images that are not scaled.
img {
image-rendering: smooth;
}Default
| Default value | auto |
| Inherited values | yes |
| Can it be animated? | no |
These are the allowed values.
| Value | Description |
|---|---|
| auto | Let the browser choose the scaling algorithm (default) |
| smooth | Use an algorithm that smooths out the colors in the image |
| high-quality | Same as smooth, but with a preference for higher-quality scaling |
| crisp-edges | Use an algorithm that will preserve the contrast and edges in the image (Chrome, Edge, Opera, and Safari uses an alternate name for the crisp-edges value: -webkit-optimize-contrast) |
| pixelated | If the image is scaled up, the nearest-neighbor algorithm is used resulting in larger pixels; if the image is scaled down, it will be the same as auto |
| initial | Sets this property to its default value |
| inherit | Inherits this property from its parent element |
Using JavaScript
The HTML element can also be styled using JavaScript and the element’s id.
document.getElementById('my_img').style.imageRendering = 'smooth';<button onclick='my_function()'>Click Here</button>
<script>
function my_function() {
document.getElementById('my_img').style.imageRendering = 'smooth';
}
</script>CSS Notes:
- The “inherit”, “initial” and “unset” keywords can be used with any CSS property to set its value
- In CSS there are many ways to express a color value in a property
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
