In this example, two rectangles are placed within a nested вЂњвЂќ element. While you wonвЂ™t be able to make elements rotate around their own center, the adjustment of the position becomes rather easy if you place the elements you want to rotate at the top left of the nested вЂњвЂќ element. However, you can use nested SVG elements to help you with this as well. The вЂњxвЂќ and вЂњyвЂќ attributes need to be adjusted as well.ДЄn element that is placed 200 pixels from the left and the top, and rotated by 90 degrees counterclockwise may disappear from the drawing space.

If you want to put a text upright, rotating it by 90 degrees wonвЂ™t do the trick. Of course, this makes it difficult to realize rotations. However, in SVG format, elements are always turned around the top left corner of the SVG drawing area. With HTML, вЂњrotate()вЂќ makes the elements rotate around their own center. This becomes very noticeable with the вЂњrotate()вЂќ function. However, the SVG interpretation of вЂњtransformвЂќ is different from the HTML one. The CSS attribute вЂњtransformвЂќ not only scales and rotates HTML elements, but SVG shapes as well. In contrast to the вЂњвЂќ element, the nested вЂњвЂќ elements allow you to change the position of multiple shapes at once. As the nested вЂњвЂќ element is 200 pixels away from the top left border, the red circle is also placed 200 pixels away from both borders.Д¬hanging the вЂњxвЂќ and вЂњyвЂќ attributes of the second вЂњвЂќ element also changes the placement of all included shapes. The circles are placed so that they are at the top left corner. In the example, a circle is being drawn on the in and outside of a nested SVG graphic. Though, within a nesting, the absolute placement is limited to the respective parent вЂњвЂќ element.

It is possible for an вЂњвЂќ elements, to be placed within another вЂњвЂќ element. The SVG format allows for the nesting of SVG graphics. However, there is a way to place SVG forms relatively within an SVG graphic. Nesting SVGs While Still Placing Them Relatively This is a challenge, especially when it comes to the вЂњвЂќ element and its complex вЂњdвЂќ attribute. With dynamic changes, calculated via JavaScript or PHP, for instance, each new element of a figure has to be altered. There, you get to adjust everything and save it as an SVG file. This problem is pretty easy to fix for static graphics, by opening the graphic in a drawing program, like Illustrator. Because, if you want to change the position of a figure that possibly consists of dozens of individual elements, the вЂњxвЂќ and вЂњyвЂќ attribute, as well as the other position defining attributes, like вЂњcxвЂќ, вЂњcyвЂќ, and вЂњdвЂќ (for the вЂњвЂќ element), have to be altered. This poses a problem when it comes to sophisticated graphics. Although the вЂњвЂќ element gives us an opportunity to group elements, it is not possible to assign a position to the вЂњвЂќ element itself. The second difference is that SVG shapes are generally placed within an вЂњвЂќ element. While, with CSS, colors and contours can be designed via CSS, a positioning via CSS isnвЂ™t even possible in SVG format. While HTML elements are placed via CSS attributes вЂњleftвЂќ and вЂњtopвЂќ, SVG elements can only be placed via вЂњxвЂќ and вЂњyвЂќ attributes (вЂњcxвЂќ and вЂњcyвЂќ attributes for circles). When it comes to the positioning of SVG elements like вЂњвЂќ or вЂњвЂќ, thereвЂ™s already a big difference to HTML regarding the syntax.
