CSS Box Shadow | CSS- Tricks. Used in casting shadows off block- level elements (like divs). The horizontal offset of the shadow, positive means the shadow will be on the right of the box, a negative offset will put the shadow on the left of the box. The vertical offset of the shadow, a negative one means the box- shadow will be above the box, a positive one means the shadow will be below the box. The blur radius (optional), if set to 0 the shadow will be sharp, the higher the number, the more blurred it will be. The spread radius (optional), positive values increase the size of the shadow, negative values decrease the size. Default is 0 (the shadow is same size as blur).

Creating Inner Shadow Effects for WPF and Silverlight. A few tricks for creating Photoshop- style Inner Shadow effects in WPF and Silverlight. Introduction. If you've ever been tasked with converting a Photoshop design into a WPF UI, you'll probably have tried the Expression Blend Photoshop Import feature. So you'll know that whilst it does a pretty good job of importing simple Photoshop files, it struggles when asked to convert the little flourishes with which designers like to top off their masterpieces. Like Inner shadows.
In this article, I'll show you a couple of ways of creating inner shadow effects in WPF, one of which also works for Silverlight. Pleased to meet you, Mr. Inner Shadow. If you've not met an inner shadow before, allow me to introduce you. Here’s a grey rectangle: And here's a grey rectangle with an inner shadow: Subtle, isn’t it? But it adds a touch of realism to the rendering. Clip Regions and Opacity Masks. Question is, how can we create an inner shadow in WPF?
Look in the System. Windows. Media. Effects namespace, and you’ll find the Drop. Shadow. Effect class, but no Inner. Shadow. Effect. Don’t let that fool you. Drop. Shadow. Effect can be used to create an inner shadow, using one of two nifty WPF features: Clip regions and Opacity Masks. Clip regions and Opacity Masks both achieve a similar effect, though in different ways. They instruct WPF to trim off, or hide, certain parts of a visual when rendering it to the screen.
Clip regions are geometries – rectangles, ellipses, or arbitrary paths, which specify the boundaries of a shape. Everything inside the geometry is rendered, everything outside ignored. They tell WPF, thus far shalt thou render, and no further. Opacity Masks are like stencils which WPF lays over the top of your element. Each pixel in your element is given the same opacity as the corresponding pixel in the Opacity Mask. If the pixel in the Opacity Mask is transparent, then WPF ignores the corresponding pixel of your element.
If the pixel in the Opacity Mask is opaque, or semi- opaque, then WPF renders that pixel of your element. Inner Shadows Using Clip.
To. Bounds. I’ll start with the simplest technique for drawing Inner Shadows: applying Clip regions using the Clip. To. Bounds property. Set this to true, and WPF will make sure that no part of an element or its children will spill outside of its borders.
This is the easiest way of using Clip regions because you don’t have to think about their geometry or worry about resizing if the element changes size: WPF uses the natural bounding- rectangle of the element as the Clip region. Here’s how I created the inner shadow shown above: < Border. Background="Light.
Gray"Border. Brush="Dark. Gray"Border. Thickness="1"Clip. To. Bounds="True"> < Border. Background="Transparent"Border. Brush="Black"Border. Thickness="1"Margin="- 2"> < Border. Effect> < Drop.
Shadow. Effect. Shadow. Depth="0"Blur. Radius="1.
Border. Effect> < /Border> < /Border> There are several things to notice here: I apply the Drop. Shadow. Effect to an element (a Border in this case) that has a solid border, but transparent fill. This produces a shadow effect on both sides of the border. The Drop. Shadow. Effect has its Shadow.
Depth set to 0 so that there’s no gap between the border and the start of the shadow. This also ensures that the shadow is even in all directions. Fiddle with Drop. Shadow. Effect’s Blur. Radius and Opacity properties if you want to vary the lightness of the shadow. There’s the Color property to experiment with too. The critical part that makes this shadow an inner, and not an all- round, shadow: the Border with the Drop.
Shadow. Effect is nested inside another border which has Clip. To. Bounds="True". This is what clips off the outer part of the drop shadow. I use negative margins on the inner border to push out its edge so that it gets clipped by the Clip region of the outer border, effectively hiding it. Another thing you can experiment with is changing the thickness of the inner border. This lets you vary the density of the inner shadow. For example, a Border.
Thickness of 1. 0 (and a Margin of –1. Want shadows on just a couple of edges? That’s easy: just turn off the appropriate lines on the inner Border using its Border. Thickness property. Here’s a rectangle with an inner shadow on just its top edge: And here’s the markup: < Border. Background="Light. Gray"Border. Brush="Dark.
Gray"Border. Thickness="1"Clip. To. Bounds="True"Width="4. Height="1. 00"> < Border. Background="Transparent"Border. Brush="Black"Border. Thickness="0,1. 0,0,0"Margin="0,- 1. Border. Effect> < Drop.
Shadow. Effect. Shadow. Depth="0"Blur. Radius="1. Border. Effect> < /Border> < /Border> Sadly, this easy- to- use method won’t work in Silverlight, because it doesn’t have the Clip. To. Bounds property. But don’t lose heart. I’ve another trick up my sleeve. Inner Shadows with the Clip Property.
A technique that works as well in Silverlight as WPF is using the Clip property to set the geometry of the Clip region. Here’s an example: < Grid> < Rectangle. Width="4. 00"Height="1. Fill="Light. Yellow"Stroke="Orange"Stroke. Thickness="2"Radius. X="8"Radius. Y="8"/> < Rectangle. Width="4. 00"Height="1.
Fill="Transparent"Stroke="Orange"Stroke. Thickness="2"Radius. X="8"Radius. Y="8"> < Rectangle. Effect> < Drop. Shadow. Effect. Shadow. Depth="0"Blur. Radius="1. Color="Orange"/> < /Rectangle.
Effect> < Rectangle. Clip> < Rectangle. Geometry. Rect="0,0,4.
Radius. X="8"Radius. Y="8"/> < /Rectangle.
Clip> < /Rectangle> < /Grid> which looks like this when rendered: As you can see, I’m using the same trick of applying the Drop. Shadow. Effect to a shape with a solid border but transparent fill, then clipping off the outer shadow, this time by setting a Clip region on the same shape. To get the background fill, I put another copy of the shape behind (using a Grid to layer the two) and set its Fill to the colour I want. The thing that makes this not quite so easy to use as the Clip. To. Bounds method is that the geometry in the Clip property has to match exactly the shape of the element you’re applying it to. If the element changes in size, the geometry has to be updated too – and WPF won’t do that automatically.
So this technique might work quite well in code, but not so straightforwardly in XAML, unless you have simple, static shapes. One tip if you do go down this route: Expression Blend has good support for applying Clipping Paths to elements.
Inner Shadows using Opacity Masks. The final technique I want to show you is drawing Inner Shadows using Opacity Masks. This is what we’re shooting for: And here’s how to make that in XAML: < Grid. Width="4. 00"Height="2. Grid. Opacity. Mask> < Visual.
Brush. Visual="{Binding Element. Name=Shape}"Stretch="None"/> < /Grid. Opacity. Mask> < Pathx: Name="Shape"Data="M9. L1. 80. 4. 11. 52,1. Fill="#FFF8. F9. 3F"Stroke="#FFAB6.
Stretch="Fill"/> < Path. Data="M1. 00. 5. 71. L1. 81. 5. 51. 02,4. Stroke="#FFAB6. 60.
Stroke. Thickness="3"Stretch="Fill"> < Path. Effect> < Drop. Shadow. Effect. Shadow. Depth="0"Blur. Radius="2. Color="Orange"/> < /Path. Effect> < /Path> < /Grid> Again, we’ve got two copies of the shape layered in a Grid, the first one to give the background colour, the one on top to create the shadow effect. The difference this time is that we’ve set the Grid’s Opacity.
Mask property. We’re taking advantage of WPF’s Visual. Brush to create the mask from the shape with the solid fill. This means that when the Grid and its contents are rendered and the Opacity Mask made from the solid shape applied, pixels outside of that base shape will not be rendered, thus neatly clipping off the outer part of the shadow created by the top shape. Note that it is important to set Stretch=”None” on the Visual.
Brush to get exact alignment of the mask with the shapes it is masking. The nice thing about this technique is that the Grid will take care of resizing everything for us, which makes it much easier to use than setting Clipping regions. One downside is that performance is not going to be quite so good, since using Opacity Masks and Visual. Brushes will require WPF to create Intermediate Render Targets where it draws the elements first before compositing them with the rest of the scene.
This could be offset to some extent by the judicious use of Bitmap Caching. Silverlight and Opacity. Masks. Whilst Silverlight does support Opacity Masks, it does not support Visual.
Brushes. So unfortunately, that rules out use of this last technique for Silverlight. Acknowledgements. I can’t claim to be the first to think of these techniques.
