In the world of web design, the use of shadows is a key technique to highlight elements and give them depth. One of the most common ways to create shadows is by using the CSS property called drop shadow. In this article, we are going to explore how to use this property to add shadows to different elements of a web page.
The power of shadows in web design
Shadows are an effective technique to create the illusion of depth in web design. Adding a shadow to an element makes it appear to rise off the page and stand out from the rest of the content. This helps draw the user's attention and guide their attention to the item in question.
In addition to the visual impact, shadows can also help improve the readability of text and distinguish different layers of content on a page.
How to create shadows with drop shadow in CSS?
To add shadows to elements using the property drop shadow In CSS, we need to specify the corresponding values for horizontal scroll, vertical scroll, blur and shadow color.
.example-element { filter: drop-shadow(2px 2px 4px rgba(0, 0, 0, 0.7)); }
In the above code, we have applied a 2 pixel horizontal shift shadow, a 2 pixel vertical shift shadow, a 4 pixel blur, and a black shadow color with an opacity of 0.7.
It is important to note that the property drop shadow It only works with elements that have content. If you want to apply a shadow to an element without content, such as an empty div, you may first need to add content to the div using a pseudo-element or a background image.
Applying shadows to text

.example-text { text-shadow: 2px 2px 4px rgba(0, 0, 0, 0.7); filter: drop-shadow(2px 2px 4px rgba(0, 0, 0, 0.7)); }
In the code above, we have applied both a text shadow and a hover shadow to the text.
