The "filter" feature in CSS is one of the attractive and practical features that can be used to apply various visual effects on HTML elements. This feature allows you to create different visual effects such as blur, brightness, contrast, and even color transformations easily on images and other website elements. Without needing to use complex image editing software, you can create appealing visual changes with just a few lines of simple code.
Using the "filter" feature in web projects provides designers and developers with greater flexibility. With the help of this feature, you can give specific atmospheres to web pages and enhance the user experience. For example, you can apply a blur filter to a background image to make the text on it easier to read, or use a sepia filter to create a nostalgic feel in images.
Let's start with a simple example. Suppose you want to blur an image:
<style>
img.blurry {
filter: blur(5px);
}
</style>
<img src="your-image.jpg" alt="A beautiful scenery" class="blurry">
In the above example, we apply the "filter" feature with the "blur" value to blur the background with a value of 5 pixels. This value indicates the degree of blur. The higher the number, the more blurred the image becomes.
Now, let's provide a line-by-line explanation of the code above:
<style> → This starts the definition of CSS styling in this tag.img.blurry → This selects the CSS class for targeting the image with the class "blurry".filter: blur(5px); → Applies the blur filter with a value of 5 pixels for blurring the image.</style> → Ends the CSS styling section.<img src="your-image.jpg" → HTML tag for adding an image with the specified source URL.alt="A beautiful scenery" → Text alternative for the image in case it fails to load.class="blurry" → Assigns the "blurry" class to the image for applying CSS styling.</img> → Ends the image tag.
With the help of this feature, you can easily enhance the visual appeal of your web pages and create a better experience for your users.
