CSS Masking is a technique used to hide or reveal parts of an element by using a mask. It is a powerful tool that allows developers to create complex visual effects and animations. In this article, we will discuss the basics of CSS Masking and how it can be used to create stunning designs.
CSS Masking is a technique that allows developers to hide or reveal parts of an element by using a mask. A mask is an image or a shape that is used to define the visible area of an element. The visible area of an element is the area that is not covered by the mask. The mask can be applied to any element, including images, videos, and text.
There are two types of masks in CSS: alpha masks and luminance masks. Alpha masks use the alpha channel of an image to define the visible area of an element. Luminance masks use the brightness of an image to define the visible area of an element.
To use CSS Masking, you need to define a mask image or a mask shape. You can define a mask image using the mask-image property. You can define a mask shape using the mask-type and mask-box-image properties.
Here is an example of how to use the mask-image property:
<div class="mask-image-example">
<img src="image.jpg" alt="Image">
</div>
.mask-image-example {
-webkit-mask-image: url(mask.png);
mask-image: url(mask.png);
}
In this example, we have a <div> element with an <img> element inside it. We have applied a mask image to the <div> element using the mask-image property. The mask image is defined in the url() function.
Here is an example of how to use the mask-type and mask-box-image properties:
<div class="mask-shape-example">
<p>This is some text.</p>
</div>
.mask-shape-example {
-webkit-mask-type: polygon;
mask-type: polygon;
-webkit-mask-box-image: url(mask.png) 30 30 repeat;
mask-box-image: url(mask.png) 30 30 repeat;
}
In this example, we have a <div> element with a <p> element inside it. We have applied a mask shape to the <div> element using the mask-type property. The mask shape is defined as a polygon. We have also applied a mask box image to the <div> element using the mask-box-image property. The mask box image is defined in the url() function and is repeated 30 pixels from the top and left edges of the element.
