SVG 描边属性

SVG 描边属性

The stroke attribute sets the color of the line drawn around an element.

Here we will look at the six stroke attributes

• stroke - sets the color of the line around an element
• stroke-width - sets the width of the line around an element
• stroke-opacity - sets the opacity of the line around an element
• stroke-linecap - sets the shape of the end-lines for a line or open path
• stroke-dasharray - sets the line to show as a dashed line
• stroke-linejoin - sets the shape of the corners where two lines meet

SVG 描边属性

The stroke attribute defines the color of the outline of an element.

The stroke attribute can be used with the following SVG elements: <circle>, <ellipse>, <line>, <path>, <polygon>, <polyline>, <rect>, <text>, <textPath>, <tref> and <tspan>.

The value of the stroke attribute can be a color name, rgb value or a hex value.

Here we use the stroke attribute to set the outline color for a polygon, rectangle, circle and a text

Here is the SVG code

Here we use the stroke attribute to define the color of three lines

Here is the SVG code

SVG 描边宽度属性

The stroke-width attribute defines the width of the stroke.

The stroke-width attribute can be used with the following SVG elements: <circle>, <ellipse>, <line>, <path>, <polygon>, <polyline>, <rect>, <text>, <textPath>, <tref> and <tspan>.

Here we use the stroke-width attribute to set the width of the outline for a polygon, rectangle, circle and a text

Here is the SVG code

Here we use the stroke-width attribute to set the width of three lines

SVG 描边不透明度属性

The stroke-opacity attribute defines the opacity of the stroke.

The stroke-opacity attribute can be used with the following SVG elements: <circle>, <ellipse>, <line>, <path>, <polygon>, <polyline>, <rect>, <text>, <textPath>, <tref> and <tspan>.

The value of the stroke-opacity attribute goes from 0 to 1 (or 0% to 100%).

Here we use the stroke-opacity attribute to set the opacity of the outline for a polygon, rectangle, circle and a text

Here is the SVG code

Here we use the stroke-opacity attribute to set the opacity of three lines

Here is the SVG code

SVG 描边线帽属性

The stroke-linecap attribute defines different types of endings for a line or an open path.

The stroke-linecap attribute can be used with the following SVG elements: <path>, <polyline>, <line>, <text>, <textPath>, <tref> and <tspan>.

The value of the stroke-linecap attribute can be "butt", "round" or "square".

Here we use the stroke-linecap attribute to set different endings for three lines

Here is the SVG code

SVG 描边线段属性

The stroke-dasharray attribute is used to create dashed lines.

The stroke-dasharray attribute can be used with the following SVG elements: <circle>, <ellipse>, <line>, <path>, <polygon>, <polyline>, <rect>, <text>, <textPath>, <tref> and <tspan>.

The value of the stroke-dasharray attribute can be "none" or a comma or space separated list of lengths/percentages that define the lengths of dashes and gaps.

Here we use the stroke-dasharray attribute to create different dashed lines

Here is the SVG code

Here we use the stroke-dasharray attribute to create different dashed outlines for a polygon, rectangle and a circle

Here is the SVG code

SVG 描边线连接属性

The stroke-linejoin attribute defines the shape of the corners where two lines meet.

The stroke-linejoin attribute can be used with the following SVG elements: <path>, <polygon>, <polyline>, <rect>, <text>, <textPath>, <tref> and <tspan>.

属性 stroke-linejoin 的值可以是 "arcs"、"bevel"、"miter"、"miter-clip" 或 "round"。

这里我们使用属性 stroke-linejoin 来创建不同的角形状
