Paths The <path> element is used to define a path. The following commands are available for path data: M : moveto L : lineto H : horizontal lineto V: vertical lineto C : curveto S : smooth curveto Q : quadratic Bézier curve T : smooth quadratic Bézier curveto A: elliptical Arc Z : closepath Define a path using the d attribute: <svg width="500" height="500"> < path d="M 0 0 L200 200 L200 0 Z" style="stroke:#000; fill:none;" /> </svg> Try It Yourself M places our "virtual pen" down at the position 0, 0. It then moves 200px down and to the right, then moves up to the position 200, 0. The Z command closes the shape, which results in a hypotenuse: All of the above commands can also be expressed with lower case letters. When capital letters are used, it indicates absolute position; lower case indicates relative position.
The <header> Element In HTML4, we would define a header like this: <div id="header"> In HTML5, a simple <header> tag is used, instead. The <header> element is appropriate for use inside the body tag. <!DOCTYPE html> <html> <head> </head> <body> <header> <h1> Most important heading </h1> <h3> Less important heading </h3> </header> </body> </html> Try It Yourself Note that the <header> is completely different from the <head> tag
Single Line Break Opening the HTML file in the browser shows that a single line break has been added to the paragraph: The <br /> element has no end tag.
