Why Use Background Blur Effects Using CSS?
Adding a blur effect to your website’s background can help you in several ways:
- Improves Readability: The blur effect softens the background, helping text and other content stand out.
- Adds Depth: A blurred background can create a layered effect, giving your design a sense of depth and sophistication.
- Enhances Focus: By blurring non-essential parts of the page, users are naturally drawn to the main content.
Understanding CSS Properties for Background Blur Effects
To create a background blur effect, you need to understand two main CSS properties:
- backdrop-filter: This property applies graphical effects like blur, brightness, or contrast to the background of an element.
- background-color with rgba: Setting a semi-transparent background color with rgba (e.g.,
rgba(255, 255, 255, 0.6)) combines nicely withbackdrop-filterfor a frosted glass effect.
Step-by-Step Code to Create a Background Blur Effect
Here’s a simple example using CSS and HTML to create a section with a Background Blur Effects Using CSS.
1. HTML Structure
Add this HTML to your web page to create a section that will contain a blurred box overlay.
<section class="slider-one">
<div class="banner_blur_box">
<h1>Innovate</h1>
<p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Maxime repudiandae aperiam, similique quidem ab corrupti veniam architecto voluptatum mollitia hic quaerat alias voluptatem. Totam laudantium magni ipsum libero et laboriosam?</p>
</div>
</section>
- Explanation: The
<section>element represents the entire background section, while<div class="banner_blur_box">contains the content with the blur effect. Inside this box, we have a title (<h1>Innovate</h1>) and some text.
2. CSS Styling
Now, let’s add some CSS to create the Background Blur Effects.
/* Background Section */
.slider-one {
background-image: url(images/Banner1.webp);
height: 100vh;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
display: flex;
align-items: center;
justify-content: center;
}
/* Blurred Box */
.banner_blur_box {
width: 75%;
padding: 10px;
background-color: rgba(255, 255, 255, 0.642); /* Semi-transparent white */
height: 80vh;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
backdrop-filter: blur(5px); /* Apply blur effect */
border-radius: 40px; /* Rounded corners */
}
/* Title Styling */
.banner_blur_box h1 {
font-size: 100px;
font-weight: 900;
background-image: url(images/Text-bg.jpg);
background-size: cover;
background-position: center;
background-clip: text;
-webkit-background-clip: text;
color: #0000006e; /* Dark, semi-transparent color */
}
/* Paragraph Styling */
.banner_blur_box p {
font-size: 22px;
font-weight: 600;
background-image: url(images/Text-bg.jpg);
background-size: cover;
background-position: center;
background-clip: text;
-webkit-background-clip: text;
color: #000;
width: 75%;
text-align: center;
margin-top: 10px;
}
- Explanation:
slider-one: This CSS targets the section and applies a full-screen background image with centered alignment.banner_blur_box: This class applies the blur effect (backdrop-filter: blur(5px);) to the box containing the text, along with a semi-transparent background color (rgba(255, 255, 255, 0.642)). This gives it a frosted glass effect.- Title and Text Styling: We added a background image effect on the text by clipping it with
background-clip: text;, giving a textured look to both the title and paragraph text.
Common Mistakes to Avoid
| Mistake | Solution |
|---|---|
| Forgetting to Add backdrop-filter | Ensure backdrop-filter is supported by your CSS and is applied on the element you want to blur. |
| Using Non-Semi-Transparent Colors | Always use rgba or hsla color formats to ensure transparency in your background color. |
| Not Centering Content Properly | Use display: flex;, align-items: center;, and justify-content: center; to make sure content is aligned in the middle of the section. |
