How SVG Uses HTML and CSS as a Paired Setup

SVG graphics generally consist of structural syntax in an HTML file interacting with stylistic syntax in a linked CSS file. If any element of interactivity exists, then a JavaScript file will also be involved in the process; this is not to be confused with animated elements, which are often defined within CSS files. Contrary to how web graphics in the past would mostly take the form of flat images, the modern SVG format relies on code spread between these three scripts working simultaneously. The HTML is the most typical file among the three to contain the code that dictates the actual shapes of the dynamically rendered images, and SVG graphics with high detail but relatively simple animations often result in HTML files with much more code than the corresponding CSS files.

This is all the case with a project by Sebin Song uploaded to the CodePen website, in which an animated graphical effect transpires the moment it is loaded. The project is inspired by the famous animated sequence for the Marvel Studios logo that precedes many films and related media, which resembles pages of an American comic book flipping downward while the logo itself materializes in front of it. Similarly to the official Marvel logo sequence, this SVG exhibition ends with an image of a proper noun establishing itself in front of what becomes a blank background. In the cases of both the Marvel logo and this SVG graphic, the name does not simplistically form in front of the changing background images with a basic technique such as a fade or a collapse from above.

While the Marvel logo sequence's method of gradually displaying its name is more elaborate than what is used by this SVG demonstration, this project nonetheless makes the changing backgrounds feel at least somewhat integrated into the formation of the name itself. The shapes comprising the name are essentially used as a "window" letting the background layer behind it remain visible, whereas the space surrounding these shapes constitutes a solid covering. This technique is similar to how image-editing software like PhotoShop lets some layers "mask" others. For more information click here https://v.redd.it/ce25am2ibzf61.
