In CSS, the property background-image: linear-gradient(90deg, silver 25%, red 75%); defines a smooth color transition across an element.
Here is the breakdown of how the browser interprets this:
- The Direction:
90deg
The angle 90 degrees tells the gradient to move horizontally from left to right.
- would go from bottom to top.
- would go from top to bottom.
- The Color Stops
The percentages (25% and 75%) act as "anchors" for the colors. They control how much of each color is solid versus how much is blending.
- Silver at 25%: The color is solid silver from the very beginning (0%) until it reaches the 25% mark of the element's width.
- The Transition: Between 25% and 75%, the browser calculates the math to blend silver into red. This is where the actual "gradient" effect happens.
- Red at 75%: Once the gradient reaches 75% of the width, it becomes solid red and stays that way until the end (100%).
Why use percentages?
Without percentages (linear-gradient(90deg, silver, red)), the transition would start at 0% and end at 100%, making the entire element look "blurry." By using 25% and 75%, you create a more defined look with solid color blocks on the sides and a controlled blend in the middle.
So I am not sure what does it mean "error" in your case ??
