This article will introduce a way to use background
and backdrop-filter
to create an interesting perspective background effect. I hope it will be helpful to everyone!
#This technique comes from a question from a group friend, how to build a top bar background effect like an ElementUI document, see the effect:
Look carefully, during the scrolling process of the page, the background of the top bar is not white, nor is it a frosted glass effect, but the background can be granulated:
To be precise, it is a frosted glass effect based on granulation. The elements are first granulated, and secondly, the edges of the elements are also blurred to a certain extent. . So, how do we achieve this effect?
The above effect may seem magical, but the principle is actually very simple. The main thing is granular background background plus backdrop-filter: blur()
.
First, we need to implement the particle background.
We use background
to achieve such a background:
<div></div>
div { background: radial-gradient(transparent, #000 20px); background-size: 40px 40px; }
The radial gradient effect from transparent to black is as follows:
It should be noted that the white part in the picture is actually transparent and can reveal the background behind it. At this time, if there are elements behind the background, the effect will be like this:
Okay, we will background: radial-gradient(transparent, #000 20px)# Replace the
black in ## with white , the effect is as follows:
div { background: radial-gradient(transparent, rgba(255, 255, 255, 1) 2px); background-size: 4px 4px; }In this way, we successfully granularize the background: Of course, the background revealed at this time can be seen It looks very stiff and not beautiful, so we also need
backdrop-filter: blur(). Let’s try it by adding one:
div { background: radial-gradient(transparent, rgba(255, 255, 255, 1) 2px); background-size: 4px 4px; backdrop-filter: blur(10px); }In this way, we have achieved what we started with Displayed effect: What needs to be noted here is the size control of
background-size and the different
backdrop-filter: blur( 10px) value will affect the effect.
background: radial-gradient() graphics, and change the
background-size, and try various different shapes of perspective backgrounds. Just give a few examples:
div { background: linear-gradient(45deg, transparent, #fff 4px); background-size: 6px 6px; backdrop-filter: saturate(50%) blur(4px); }Here
linear-gradient() is used instead of
radila-gradient():
