What's wrong with my code?

Question

<circle svg width=1000 height=1000 cx=30 cy=30 r=20 fill=red></svg></circle>

Answer 1

there 's no thing called height-width in svg. Also you forgot to place quotation marks. fill:red should be in style=" …"

Answer 2

<svg> <circle cx="30" cy="30" r="20" style="fill:red"/> </svg>
