Use when transforming web designs to WPF, converting CSS animations to Storyboards, implementing CSS border-radius clipping, CSS pseudo-elements (::before/::after), or CSS transforms in XAML.

HTML/CSS → WPF XAML 변환 가이드

CSS → WPF 핵심 매핑 테이블

핵심 규칙 요약

1. Duration은 항상 인라인

Copy<!-- ✅ -->
<DoubleAnimation Duration="0:0:3" />
<!-- ❌ StaticResource 바인딩 불가 -->

2. 둥근 모서리 클리핑은 Border.Clip + RectangleGeometry

Copy<Border CornerRadius="20">
    <Border.Clip>
        <RectangleGeometry RadiusX="20" RadiusY="20">
            <RectangleGeometry.Rect>
                <MultiBinding Converter="{x:Static local:SizeToRectConverter.Instance}">
                    <Binding Path="ActualWidth" RelativeSource="{RelativeSource AncestorType=Border}" />
                    <Binding Path="ActualHeight" RelativeSource="{RelativeSource AncestorType=Border}" />
                </MultiBinding>
            </RectangleGeometry.Rect>
        </RectangleGeometry>
    </Border.Clip>
</Border>

3. 회전 요소는 Canvas 내 배치

Copy<Canvas>
    <Rectangle Canvas.Left="45" Canvas.Top="{Binding ...}" RenderTransformOrigin="0.5,0.5">
        <Rectangle.RenderTransform>
            <RotateTransform Angle="0" />
        </Rectangle.RenderTransform>
    </Rectangle>
</Canvas>

4. ContentPresenter는 Canvas 밖 Grid에 배치

Copy<Grid>
    <Canvas><!-- 회전 요소들 --></Canvas>
    <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
</Grid>
