使用CSS Flexbox或Grid創(chuàng)建HTML5兩列布局。1. Flexbox通過display:flex將容器設為彈性布局，左右列各占50%寬度；2. Grid通過display:grid和grid-template-columns:1fr 1fr實現(xiàn)等寬列，gap設置間距；3. 響應式設計用媒體查詢在屏幕小于768px時改為縱向排列，F(xiàn)lexbox用flex-direction:column，Grid調整模板為單列。
To create a two-column layout in HTML5, you can use CSS rather than outdated table-based methods. Modern layouts rely on CSS Flexbox or CSS Grid, both of which are flexible, responsive, and easy to manage.
Using Flexbox for a Two-Column Layout
Flexbox is ideal for one-dimensional layouts like rows or columns. Wrap your columns in a container and apply display: flex.
Example:
??
??
Add this CSS:
.container {??display: flex;
}
.column-left {
??width: 50%;
??padding: 10px;
}
.column-right {
??width: 50%;
??padding: 10px;
}
Using CSS Grid
Grid is perfect for two-dimensional layouts but works great for simple columns too.
Same HTML structure as above, but use this CSS:
.container {??display: grid;
??grid-template-columns: 1fr 1fr;
??gap: 20px;
}
This creates two equal columns with a 20px gap between them.
Adding Responsiveness
On small screens, stack the columns vertically using a media query:
@media (max-width: 768px) {??.container {
????flex-direction: column;
??}
}
If using Grid, it will automatically adjust if you change the template:
@media (max-width: 768px) {??.container {
????grid-template-columns: 1fr;
??}
}
Basically just pick Flexbox for simpler alignment needs or Grid for more control. Both work well in modern browsers and keep your HTML5 clean and semantic.

如何制作HTML5圖像圖響應
Sep 17, 2025 am 04:34 AM
要使HTML5圖像映射響應式，可通過JavaScript動態(tài)縮放坐標或使用CSS絕對定位覆蓋元素；首先確保圖像本身響應式，然后在頁面加載和窗口調整時通過JavaScript根據(jù)原始與當前尺寸比例重新計算area區(qū)域坐標，或改用百分比定位的透明鏈接覆蓋在圖像上來實現(xiàn)跨設備適配，最終保證交互區(qū)域隨圖像正確縮放，兩種方法各有適用場景，JavaScript方案兼容原有結構，CSS方案更簡潔無需腳本，應根據(jù)項目需求選擇，且均需測試多屏效果并確保觸控區(qū)域足夠大，推薦復雜地圖用JavaScript法，簡單布局
