Hi Friends, how do we recreate a Figma Style like this in Kobweb?
Here, I want to create a linear-gradient that is made up of a color and another linear-gradient.
Basically, the child linear-gradient is lightened by mixing a pinch of white with it.

i am not sure my idea may be help full. try it using html, css after this site open it for css to modifier.

Thanks Meet, I'll check it out

css2kobweb is great and should help, although please file issues if you find something that doesn't convert correctly. Thank you @Meet for linking it!

Linear gradients come from the background property (https://developer.mozilla.org/en-US/docs/Web/CSS/gradient/linear-gradient).

Here's an example of me using it in my blog site: https://github.com/bitspittle/bitspittle.dev/blob/c4b48f08a4c014da80911562979bea4a[…]tspittle/site/components/widgets/blog/koverbadge/GradientBar.kt

Thanks David
A simple gradient is easy to create in Kobweb (thanks to its simple APIs) 👌

But I haven't been able to find a way to mix a color with a gradient yet. It's probably a CSS limitation only, because Kobweb exposes access to all CSS functions/properties.

In that case, maybe I'll just create a normal gradient and write an overlay composable for it.

Still, thanks to both Meet and David for helping out.

So far, I'm enjoying the Android-like APIs on Kobweb 🙌 it's allowing me to write the web app quicker than I anticipated 👏

[David Herman]

I really appreciate you saying it's allowing you to write the app faster than you anticipated!

What do you mean by "mix a color with a gradient"?

[Shubham Singh]

If you see in the image above, the bottom item is a gradient in itself (made of red and pink)

But the top item, the one that looks white, is put above the red-pink gradient to make it look lighter

If I remove that white layer, the gradient looks much darker

So I was wondering if creating something like that is possible purely using CSS properties to avoid having to write 2 separate composables (i.e. one for gradient and one for the white overlay)

[David Herman]

Ah I see, like a blending

[Shubham Singh]

Exactly

[David Herman]

I'm looking into background stuff right now. Meanwhile, isn't there a mode where Figma shares the HTML needed to generate something?

[Shubham Singh]

I think it should be there in dev mode
I'm not sure the Figma file I have allows it, but I'll check and let you know in a while

[David Herman]

So there is a way to specify a background with a base color and a linear gradient, but I can't seem to set a blend mode that actually lightens in that much

[David Herman]

I think the easiest think to do is something like this (the two composables approach, which you may have already stumbled upon):

Box {
    val size = 200.px
    Box(
        Modifier
            .size(size)
            .backgroundImage(
                linearGradient(LinearGradient.Direction.ToRight, Colors.Blue, Colors.Red)
            )
    )
    Box(
        Modifier
            .size(size)
            .backgroundColor(Colors.White.copyf(alpha = 0.4f))
    )
}

[David Herman]

There, the outer box is for stacking. The inner boxes are arbitrary, something to create a background color on. (A Div would have also been fine)

[David Herman]

You can look up blend modes and play with this idea:

Box(Modifier
    .size(200.px)
    .background(
        Colors.Green,
        Background.of(
            image = BackgroundImage.of(linearGradient(LinearGradient.Direction.ToRight, Colors.Blue, Colors.Red)),
            blend = MixBlendMode.Lighten
        ),
    )
)

but I wasn't able to get something that did what you were asking (lightening the pink gradient with a splash of white)

[Shubham Singh]

Understood
Thanks a bunch for your time David 🙌

[David Herman]

My pleasure!

If you ever get Figma to show you the HTML it recommends, let me know.
