How to use a color picker from my screen
Article Introduction：The color selection can be achieved through the screen color picker, which is easy to operate and practical. Common tools include Windows' "magnifying glass", ColorPicker, macOS's "digital colorimeter", and cross-platform online tools. When using it, press the shortcut key (such as Ctrl/Cmd C) to activate the straw tool, and click on the target area to copy the color value. Techniques include observing color changes and selecting the closest color, sampling multiple points to average, and using magnification preview to improve accuracy. Application scenarios cover UI design, CSS style, brand color extraction, etc., but attention should be paid to the impact of screen brightness and device differences on color accuracy. It is recommended to take colors in standard display mode and combine multiple devices or professional color calibration tools to ensure consistency.

How to use the :nth-child() pseudo-class?
Article Introduction：:nth-child() pseudo-class is used in CSS to accurately select specific child elements based on element position. Its basic syntax is element:nth-child(n), which can select the nth child element, and supports odd, even and an b formulas, such as 2n 1 or n 3, respectively, to realize odd line selection or custom interval and starting point. For example, tr:nth-child(even) adds background color to even rows of the table. Unlike :nth-of-type(), :nth-child() calculates all child elements, while the former only calculates the same element. Common uses include zebra pattern tables, gallery layouts, navigation menus and form typesettings. When using them, you need to use them flexibly in combination with specific HTML structures.
