On this diagonal, we place the given color points – Pink at 0%, purple at 50%, and cyan at 100%. In our case, this is the diagonal line from the bottom left to the top right. Next, we draw the diagonal of the rectangle closest to the gradient-axis. I try to explain step by step what this means: First, we draw a vertical axis and rotate it by 36 degrees. What happens now can best be described as follows: Draw a gradient at an angle of 36 degrees, but make sure that all the colors indicated are visible. This happens at the same place where we indicated the direction before: In addition to the direction from a side or a corner, it is also possible to specify an exact angle. Especially if you want the gradient to be parallel to some other line in your design. Different widths can easily result in a non-homogeneous look. Since the angle here depends on the width of the element, you should be careful when defining a gradient for a button, for example. We will have a closer look at this in the next part. You can see that the axis that runs along the middle color stop is positioned exactly on the diagonal opposite to the one defined in CSS (bottom-left to top-right). For example, an aspect ratio of 2:1 results in an angle of approximately 26.5 degrees. If the aspect ratio of the element changes, the gradient's angle is adjusted to the angle of the diagonal. For a square, this results in an angle of precisely 45 degrees. The angle of the gradient is determined by the size of the element. Now the gradient runs from the lower-left corner of the element to the upper right corner. Linear-gradient( to top right, #f09, #3023AE, #0ff) This can be changed, for example, by putting to top right as the direction in front of the color values: If only colors are specified, the gradient runs from top to bottom. Not even the position of the colors is necessary. For a simple gradient, it is sufficient to specify some colors.
Nowadays, this is fortunately much easier. In the beginning it was very challenging to implement them because every browser used its own syntax. Gradients have existed in CSS for over ten years. There's gonna be some trigonometry involved. If you are also interested in this, well. So I've been digging very deep to find out what's really going on when I assign an angle to a gradient in CSS, Figma, or Sketch. It becomes even more confusing when you look at how a gradient behaves when the element is resized (At least for me it was confusing).
CSS COLOR CODES GRADIENT CODE
In the end, copying the CSS code often leads to subtle, but intolerable differences in the design. Especially the angle of a gradient sometimes seemed more like a random product to me. Figma, I always had the feeling that gradients in graphics programs behave somewhat differently than gradients created with CSS. Even though it is now easy to copy CSS code for gradients directly from e.g. Ensure you use ios/**.xcworkspace file instead of ios./**.Do you know the feeling when a subject never lets you go? In the last years, I have worked with different graphics programs and have written many lines of CSS.Ensure pod 'BVLinearGradient', :path => './node_modules/react-native-linear-gradient' is present in your ios/Podfile.( react-native link for React Native 0.60). Ensure you have followed the installations steps correctly.Troubleshooting iOS build fails: library not found, "BVLinearGradient" was not found in the UIManager You can see this component in action in brentvatne/react-native-login.
UseAngle is used to turn on/off angle based calculation (as opposed to start/ end).ĪngleCenter is the center point of the angle (will control the weight and stretch of the gradient like it does in photoshop. startĪn optional object of the following type:, to achieve a gradient with a 45 degrees angle, with its center positioned in the view's exact center.
In addition to regular View props, you can also provide additional props to customize your gradient look: colorsĪn array of at least two color values that represent gradient colors.
