About svg Tag in svg On the reuse of graphics , It's through labels defs To solve the .
for instance ： Red circles in the graph ● And yellow circles ● Are reusable elements . The structure is the same , Just the difference in color and position .

About figure：
<figure Tags specify independent stream content （ Images 、 Chart 、 Photo 、 Code and so on ）.

<figure The content of the element should be related to the main content , At the same time, the position of the element is independent of the main content . If deleted , Should not affect document flow .

About perspective-origin：
perspective-origin Attribute definitions 3D The element is based on X Axis and Y Axis . This property allows you to change 3D Bottom position of element .

By definition perspective -Origin attribute , It is a child element of an element , Perspective , Not the elements themselves .

perspective-origin: x-axis y-axis;

x-axis	
 Define the view in  x  Position on the shaft . The default value is ：50%.

 Possible value ：

left

y-axis	
 Define the view in  y  Position on the shaft . The default value is ：50%.

 Possible value ：

If you are learning python perhaps Java Even if it is C If you have any problems, you can leave me a message , Because in the early stage of learning, novices always take many detours , At this time, if there is no one to help, it is easy to give up . There are many such examples around. Many people change their majors and directions as they learn , Not only their own problems, but also the lack of correct learning . So as a passer-by, I hope to leave a message to me if you have any questions , It's not help, it's just a matter of typing a few lines easily .

Here you are python,Java Learning materials and interesting programming projects , More difficult to find resources . Anyway, it's not a loss to see .
