Final answer:
The code to load the 'tablet.css' style sheet for screen devices with widths between 480 and 780 pixels is a link element with a specific media attribute containing the relevant media query.
Step-by-step explanation:
To load the tablet.css style sheet for screen devices with a width ranging from 480 pixels to 780 pixels, you would use the following HTML link element:
<link rel="stylesheet" media="screen and (min-width: 480px) and (max-width: 780px)" href="tablet.css">
This code snippet should be placed within the <head> section of your HTML document. It uses the media attribute to specify a media query that targets screen devices within the desired width range, ensuring that tablet.css is only applied when those conditions are met.
To create a link element that loads the tablet.css style sheet for screen devices whose width ranges from 480 pixels up to 780 pixels (inclusive), you can use media queries in the HTML code. Here's an example:
<link rel="stylesheet" href="tablet.css" media="screen and (min-width: 480px) and (max-width: 780px)">
In the example above, the link element has the rel attribute set to "stylesheet", the href attribute set to "tablet.css", and the media attribute using a media query to specify the desired range of screen widths.
