Creating a Firework Effect:
If you're looking to create a firework effect using CSS, it can be quite challenging with just one element. To achieve this, you'd need multiple elements representing the spokes of the firework. Positioning them absolutely and rotating them by specific angles will give the desired effect. The animation can then be accomplished using linear gradients and adjusting their positions.
Here's an example of how you can create a basic firework effect using CSS:
.firework {
position: absolute;
top: 100px;
left: 100px;
border-radius: 30%;
height: 64px;
width: 2px;
background: linear-gradient(to top, red, red);
background-repeat: no-repeat;
background-size: 100% 64px;
background-position: 0px -64px;
transform-origin: bottom;
animation: firework-0 1s 1;
}
.firework:nth-child(2){
transform: rotate(36deg)
}
/* More 'firework' classes for rotation angles */
@keyframes firework-0 {
0% {
background-position: 0px 64px;
}
50% {
background-position: 0px 0px;
}
100% {
background-position: 0px -64px;
}
}
Note that reducing the number of elements by using pseudo-elements is also possible but requires some tweaking.
Advanced Firework Effect with CSS:
If you want your firework lines to appear separate yet arranged in a circle formation, a more complex animation is needed. By incorporating transparency in a gradient and animating the background size and position, you can achieve this effect.
Check out the following CSS code snippet for a more detailed firework animation:
.firework {
position: absolute;
top: 100px;
left: 100px;
border-radius: 30%;
height: 64px;
width: 2px;
background: linear-gradient(to top, transparent 32px, red 32px);
background-repeat: no-repeat;
background-size: 100% 64px;
background-position: 100% calc(100% - 32px);
/* Animation properties */
}
Using the 'calc' function in background position ensures the correct positioning of the gradient for smooth animation.
Creating a Firework Effect Using SVG:
To achieve intricate firework effects, consider utilizing Scalable Vector Graphics (SVG). SVG provides a more precise toolset for such animations and is easier to maintain. Here's how you can use SVG for a firework effect:
The SVG code snippet below demonstrates how you can create visually appealing firework lines. Adjusting stroke dash attributes and animating them will give the desired explosive effect:
svg{
width: 128px;
height: 128px;
}
line{
stroke: red;
animation: firework 1s 1;
stroke-dasharray: 32 32;
stroke-dashoffset: -32;
}
@keyframes firework{
from{
stroke-dashoffset: 32;
}
to{
stroke-dashoffset: -32;
}
}
For different firework effects, adjust the line coordinates and stroke attributes accordingly within the SVG environment.
