In the following code snippet, what value is given for the left margin? margin: 5px 10px 3px 8px;

The value for the left margin in the given shorthand property margin: 5px 10px 3px 8px; is indeed the first number associated with left in the clockwise margin setting. In CSS, the margin shorthand property sets the margins for the top, right, bottom, and left sides of an element, in that specific order.

The first value represents the top margin (5px), the second value is the right margin (10px), the third is the bottom margin (3px), and the fourth value corresponds to the left margin (8px). Therefore, when identifying the left margin based on this declaration, it actually corresponds to the fourth value, which is 8px.

So in this case, the correct answer for the left margin from the given margin declaration should be 8px. It's important to remember the order in which the values are presented to correctly determine the margins for each side of an element.
