title: How to fill the whole canvas with specific color?
body: <p>How to fill the whole HTML5 <code>&lt;canvas&gt;</code> with one color.</p>
  <p>I saw some solutions such as <a href="https://stackoverflow.com/questions/20488590/set-backgroundcolor-styles-and-opacity-to-html5-canvas">this</a> to change the background color using CSS but this is not a good solution since the canvas remains transparent, the only thing that changes is the color of the space it occupies.</p>
  <p>Another one is by creating something with the color inside the canvas, for example, a rectangle(<a href="https://stackoverflow.com/questions/11702650/html5-canvas-how-to-fill-a-specific-context">see here</a>) but it still does not fill the whole canvas with the color (in case the canvas is bigger than the shape we created).</p>
  <p>Is there a solution to fill the whole canvas with a specific color?</p>
