CSS box bulge

CSS Box Bump

In web design, boxes are one of the most common elements, and we often need to create some special effects with them. The embossed box effect is a very common and aesthetically pleasing design. This article will detail how to use CSS to achieve this effect, giving your pages a more vibrant look.

I. Basic Concepts

Before implementing embossed boxes, let’s first understand the concepts behind the embossed effect. embossed boxes essentially extend the border or background color on one or more sides of the original box, creating a more three-dimensional and layered appearance.

In CSS, we can use the box-shadow and transform properties to create a box-bulging effect. Below, we’ll explain how to implement each method.

Second, Using the Box-shadow Property to Create a Box-Bulging Effect

The box-shadow property is used to add a shadow effect to an element. By setting different shadow parameters, we can simulate a box-bulging effect. Here’s a simple example:

.box {
width: 200px;
height: 200px;
background-color: #f0f0f0;
box-shadow: 10px 10px 0 0 #333;
} 

In the code above, we add a shadow effect to a box with a width and height of 200px. The parameters for the box-shadow property are the horizontal offset, vertical offset, blur radius, shadow spread radius, and shadow color. By setting the horizontal and vertical offsets to non-zero values, we can create a bulging effect for the box.

Below is the result of the above code:

<div class="box"></div>

<!-- Result -->

Third, Using the transform Property to Create a Bulbous Box

In addition to the box-shadow property, we can also use the transform property to create a bulging effect for the box. Specifically, we can combine it with the translate method to shift the box, giving it a three-dimensional effect. Here’s an example:

.box {
width: 200px;
height: 200px;
background-color: #f0f0f0;
transform: translate(10px, 10px);
}

In the code above, we apply the transform property to a box with a width and height of 200px and set the translate method’s parameters to 10px, 10px. This creates a bulging effect on the box’s lower right corner.

The following is the rendering of the above code:

<div class="box"></div>

<!-- Effect Image -->

Fourth: Combining the box-shadow and transform properties

In addition to using the box-shadow and transform properties individually, we can also combine them to create more complex box-extrusion effects. For example, we can apply both the box-shadow and transform properties to a box to create a more three-dimensional and vivid effect.

Here is a sample code:

.box {
width: 200px;
height: 200px;
background-color: #f0f0f0;
box-shadow: 5px 5px 0 0 #333;
transform: translate(5px, 5px);
}

In the above code, we use the box-shadow and transform properties to set a box, thereby achieving a box with both shadow and protrusion effects.

Below is the effect of the above code:

<div class="box"></div>

<!-- Effect Image -->

V. Summary

Through this article, we learned how to use the CSS box-shadow and transform properties to create a variety of box-shadow effects. We can use these two methods individually or in combination to create a variety of box-shadow effects based on actual design needs.
