How CSS lays out the Holy Grail layout_Using floats and negative margins to achieve core structure
The middle column fell because the parent container did not set height or did not trigger BFC, causing the height to collapse, and the HTML structure was wrong (the middle column was not brought to the front); the correct way is to write the middle column at the front, set width: 100% and use margin to leave side column space, and use float to fix the width and pull back the side column with negative margin.

How to implement multi-line text overflow and display ellipses in CSS_Use the line-clamp attribute to process text
Line-clamp is not limited to the WebKit kernel. Chrome, Edge (Chromium version), Safari and Firefox119 are all supported, but Firefox118 and earlier versions are not recognized at all; it needs to be used with the three-piece set of display:-webkit-box, -webkit-box-orient:vertical and overflow:hidden, and the parent container must be block-level, have a clear height or max-height.

If max-width height:auto fails in IE, you need to add width:auto to fix it: img{max-width:100%;width:auto;height:auto;}, use setTimeout to delay redrawing during dynamic loading, and use padding-top to simulate the aspect ratio when downgrading IE8.

How to quickly locate style files in CSS projects_Use BEM specifications to keep class names associated with components
The core value of BEM is to align the class name with the file path to achieve rapid positioning; it is necessary to ensure that the sourcemap is turned on, compression verification is disabled, the block name and directory name are unified, and the class name is confirmed to be truly output through the HTML source code or console.

How to make a notification bar with a close icon using CSS_Using flexbox to align buttons
The close button is not aligned because Flexbox does not have main axis/cross axis alignment, so you need to use a combination of justify-content and align-items; to center the icon, use display:flex align-items:center; when hiding, you should give priority to using opacity visibility transform animation to avoid layout collapse; for IE11 compatibility, you need to use margin-left:auto instead of flex:1 and double-write the -align attribute.

How does CSS achieve the random generation effect of background color_Combining CSS variables and JS dynamic calculation
Pure CSS cannot generate truly random colors. You must use JS to calculate the HSL value and write it into a CSS variable, and then apply it dynamically through hsl(var(--h), var(--s)%, var(--l)%); you need to preset fallback, control the value range, add transition and act on the target element.

How to quickly center a positioning box with CSS_Using transform negative offset and box model
Top:50% and left:50% must be configured to achieve centering, because transform:translate(-50%,-50%) is offset relative to its own width and height. You need to first use top/left to position the edge of the element to the center line of the parent container, and then use translate to pull back half of its own width and height to complete the center alignment.

How CSS solves the problem of grid item misalignment_Using the grid-template-rows specification
The common reason for height collapse is that the parent container has no height, and 1fr has no reference base; you need to add min-height (such as 100vh), and note that box-sizing, scroll bars, and IE11 do not support the fr unit.

How to implement semi-transparent mask background on mobile terminal with CSS_through rgba color mode setting
rgba() is the only reliable and direct solution to achieve translucent masking on the mobile terminal. It has good compatibility, clear semantics, and does not trigger reflow; opacity (affects child elements) and transparent (no translucent effect) should be avoided. The recommended alpha value is 0.4~0.9. It must be used together with the background-filter and pay attention to the hierarchy.

Linear-gradient must be used for the background or background-image attribute. The starting direction can be omitted (tobottom is the default). The colors need to be separated by commas.
