To make a row of items wrap onto the next line when there isn't enough space in a Flexbox layout, you would adjust the flex-direction property to "column" (for vertical stacking) and flex-wrap to "wrap." This allows the items to stack vertically when space is limited.

The mask-composite property in CSS is used to determine how a mask image should be combined with the element it's applied to. It's used to control the blending mode of the mask image with the element, allowing for various effects.

To include a custom font in your webpage using CSS, you use the font-family property and specify the font's name. You need to first import the font into your CSS file or link to an external font file, and then you can reference it using the font-family property in your CSS rules. This allows you to apply the custom font to specific text elements on your webpage.

In CSS, the min() function returns the minimum value among its arguments, while the max() function returns the maximum value. These two functions are complementary but serve different purposes. The clamp() function, on the other hand, allows you to set a value within a range, ensuring it stays between the minimum and maximum values provided as arguments.

The primary purpose of the filter property in CSS is to apply visual effects to elements. This property allows you to add various effects like blurring, brightness adjustment, and grayscale to an element. It's commonly used for image effects and enhancing the visual appearance of web content.

The device-width feature is commonly used in media queries to detect the width of the viewport. It specifically targets the width of the output device, which is important for creating responsive designs that adapt to different screen sizes. By using device-width in media queries, you can apply different styles and layouts based on the device's screen width.

The primary purpose of the grid-template-areas property is to specify the layout of the grid by assigning a name to grid areas. This allows for a visual representation of the grid structure and helps in creating complex and responsive layouts with CSS Grid.
