I wanted to use matrix property for my animation but it doesn't work!
What i wanted to use was scaling element just horizontally. i know i can use width or padding for that but as you know, its not good for performance.

Describe the solution you'd like
I checked anime set supported transform values, [validTransforms] arr

Selection Sort, for example, makes the algorithm look extremely (impossibly) good at first glance - O(n) - because it's not showing the majority of the steps.

Instead of

    for (var j = i + 1; j < D.length; j++) {
        if (D[j] < D[minJ]) {
            tracer._select(j);
            minJ = j;
            tracer._deselect(j);
        }
    }

it has to be more like

    for (var j

Hi,
I am installing manim. But there is a small issue in the documentation website:
Its really a small thing, but for beginner it could be a big deal.
https://www.eulertour.com/learn/manim/installation/windows.html

its written
"Install manim python dependencies with pip install -r requirement.txt"
but it should be
"Install manim python dependencies with pip install -r requirements.txt"

Suggestion

We should add a .travis.yml and set up Travis CI. Although Hero has a limited test suite it's still useful to make sure that the project compiles 😂

It would be awesome and provide to your doc a fresh user-friendly experience. For example, slate.js have done it and it is awesome, you can easily find your features and go from one place to another, so... here my feature request, what do you think about that :)?

Was somebody able to make this thing work with react and functional components? Would be great if somebody could share some ideas.

Is there any way to implement horizontal radio button group?

Hi, by just following your readme nothing happens when I add one of your ItemAnimators. Is there maybe documentation missing?

Is it necessary to set a duration? Is it necessary to always call notifyItemInserted() or notifyItemRemoved()?

As per documentation, setting useSourceImageAspectRatio should hide the menu with other ratios options. This used to be true in v2.2.2, but not anymore in v2.2.4.

This is not an issue but an observation. I no longer use storyboards for my view. Today I faced an issue with Skeletonview when I added it to my UITableViewCell, animations, frames everything was working wrong... did a lot of permutation combinations turning the properties on and off. Finally found that when you add elements in UITableViewCell you should add it to contentView and not to th

We could add easily repeating gradient

We can find the concept in css

We need for that the number of repetitions
We could add parameter to the GradientMode or I prefer

When adjusting alpha on a pixel from the color picker it's quite easy to "whiff" the alpha bar and replace your current color with black because the SV box's area for some reason extends several pixels below the alpha bar's. Demonstration in the below image:

I'd recommend the alpha

The problem

https://barba.js.org/examples/ has two Codepen links. The font choice makes it hard to understand what's going on.

Description

Expected behaviour

Pen makes it clear which things are filler text and which things are images. In the pen with text links, it is clear that the links are links.

Actual behaviour

Today I experimented with text in svg.js and it seems newLine() doesn't have enough documentation (and the behavior was unexpected for me).

Here is the example from the documentation for Text:

var text = draw.text(function(add) {
  add.tspan('Lorem ipsum dolor sit amet ').newLine()
  add.tspan('consectetur').fill('#f06')
  add.

I want to run the Example app, I

1. yarn install in the package directory

I get the following errors when running react-native run-ios.

It seems like the npm packages from devDependencies conflict wit
