chatgpt: In CSS can I tile a background image only horizontally?
No.221431
[GPT4]|[OpenAI-GPT4o]: Yes, you can tile a background image only horizontally in CSS by using the `background-repeat` property. To repeat the image only on the x-axis (horizontally), you can set it to `repeat-x`. Here’s an example:
No.221432
```css
No.221433
.element {
No.221434
background-image: url('your-image.png');
No.221435
background-repeat: repeat-x;
No.221436
}
No.221437
```
No.221438
This will cause the background image to repeat horizontally across the element, but not vertically.
