What is SVG viewport?

The viewport is the visible area of the SVG image. An SVG image can logically be as wide and high as you want, but only a certain part of the image can be visible at a time. The area that is visible is called the viewport. You specify the size of the viewport using the width and height attributes of the element.

Does the size of an SVG matter?

SVGs are Resolution-Independent From the point of view of file size, it doesn’t really matter at what size the image is rendered, simply because those instructions remain unchanged. That said, there’s something that can have a negative impact on SVG file size, i.e. how complex the image is.

What’s the difference between a viewport and a viewbox in SVG?

The viewport is like a window you look through to see an SVG’s content. The viewBox is similar to the viewport, but you can also use it to “pan” and “zoom” like a telescope. Control the viewport via width and height parameters on the svg element. Control the viewBox by adding the attribute viewBox to the svg element.

How big is the viewbox in SVG number 4?

In SVG number 4 in the example above we’ve set the viewBox width and height to 100, which is double the size of our viewport. This “zooms out” and shows double the content, thereby again revealing the entire circle. In the fifth SVG our viewBox is set to a width and height of 25, which is half the size of our viewport.

What’s the default height and width for SVG?

# The height and width attributes. So a rule like svg {width: 100%; height: auto;} will cancel out the dimensions and aspect ratio you set in the code, and give you the default height for inline SVG. Which, as mentioned above, will be either 150px or 100vh, depending on the browser.

How does the panning work in SVG viewbox?

The first number controls the horizontal position, and the second controls the vertical position. To pan right, increase the first number. To pan left, decrease the first number. To pan down, increase the second number. To pan up, decrease the second number. Take a look at how this panning works in this example.
