    How to create a print-friendly stylesheet CSS tutorial
    To create a print-friendly style sheet, first use @mediaprint or link print.css file to separate the print style; secondly, hide irrelevant elements such as navigation bar, sidebar and remove background to save ink; finally adjust the font size, font type and margins to improve readability. The specific steps include: 1. Specify the printing style through the @mediaprint rule or HTML link; 2. Set display:none to hide non-essential elements in the printing style, and set the background to white, the text to black, and the link to display the URL; 3. Set the font size to 12pt, use serif fonts, set the margins and the adaptive width of the picture to avoid forced horizontal printing. During testing, you can verify the effect by exporting PDF.

  • What is the difference between using opacity: 0 and visibility: hidden?
    What is the difference between using opacity: 0 and visibility: hidden?
    When using opacity:0, the elements are transparent but still occupy space, interactable, and support transition animation; when using visibility:hidden, the elements are not visible but still occupy space, but do not respond to interaction, and child elements can override this setting. Neither element is removed from the layout, but the behavior and applicable scenarios are different: 1. opacity:0 maintains functionality and animation capabilities; 2. visibility:hidden blocks interaction and allows child elements to be displayed; 3. Transition animation can be used on opacity, but cannot be used for visibility; 4. Screen readers may still read these two hidden elements, and other methods should be used if they need to be completely hidden.

    How to create a custom timing function with cubic-bezier()?
    To customize the cubic-bezier() timing function of CSS, 1.

Common presets such as ease, ease-in, etc. are the abbreviation of built-in curves, but fine control needs to be defined manually; 3. Select the control point and can be assisted by online tools to observe the velocity changes corresponding to the steepness of the curve. If the Y axis is less than 0, there will be rebound, and the X axis may regress beyond the range; 4. Pay attention to good compatibility when using, the value cannot exceed the range, and the multi-attribute transition should be unified; 5. Sample code. c in transition-box

  • What is a subgrid and what problem does it solve?
    What is a subgrid and what problem does it solve?
    CSS subgrid (Subgrid) is a feature in the CSSGrid layout module that allows mesh items to inherit the track size (columns and rows) of their parent grid. Mainly solves the problem of maintaining alignment consistency in nested layouts. When using it, you need to set grid-template-columns:subgrid to allow the subgrid to follow the parent structure. Suitable for scenarios such as forms, card components and dashboards. Modern browsers support well, but are not compatible with IE11 and earlier versions. In addition, sub-grids are only suitable for direct child elements, and deep nesting needs to be applied layer by layer.
