Inlined

// this method just generates blocks with random size and color for examples below
void RandomBlock(IContainer container)
{
    container
        .Width(Placeholders.Random.Next(1, 5) * 20)
        .Height(Placeholders.Random.Next(1, 5) * 20)
        .Border(1)
        .BorderColor(Colors.Grey.Darken2)
        .Background(Placeholders.BackgroundColor());
}

// example usage:
.Padding(20)
.Border(1)
.Background(Colors.Grey.Lighten3)
.Inlined(inlined =>
{
    inlined.Spacing(20);
    inlined.AlignLeft();
    inlined.BaselineBottom();

    foreach (var _ in Enumerable.Range(0, 20))
        inlined.Item().Element(RandomBlock);
});
