10个开发人员常犯的错误以及如何像专业人士一样修复它们

作为前端开发人员,我们必须考虑以下 10 个可能让项目和客户蒙受损失的错误。

1. 未优化图像

如果您使用高分辨率图像而未针对网络进行优化,则会导致页面加载缓慢。相反,请压缩图像并使用适当的格式,例如照片使用 JPEG 格式,图形使用 PNG 格式。TinyPNG ImageOptim 等工具可以帮助减小文件大小而不会牺牲质量。

 

2. 忽略移动媒体查询

许多开发人员没有考虑网站在不同设备上的外观,这会损害移动设备上的用户体验。响应式设计至关重要。使用媒体查询根据屏幕尺寸调整布局和样式。

 

3. 使用内联样式

直接在 html 中(内联)编写样式似乎很快,但它会使代码变得混乱且难以维护。最好将 css 保存在单独的文件中,以便可以重复使用样式。

 

4. 标题标签使用不当

标题(如 <h1><h2>)应正确使用,以确保良好的结构和 seo。误用它们会让搜索引擎和用户感到困惑。例如,使用 <h1> 作为主标题,后续标题应符合逻辑。

 

5. 使用样式类来挂接 JavaScript 钩子

对样式和 JavaScript 函数使用同一个类是一种不好的做法。如果更改样式类,可能会破坏 JavaScript 功能。相反,请使用数据属性来挂接 JavaScript

 

6. 留下多余的样式

随着时间的推移,当您修改网站时,未使用或重复的 CSS 可能会累积起来。这种“CSS 膨胀”会减慢加载时间。请始终清理 CSS 并删除未使用的样式。PurifyCSS UnCSS 等工具可以提供帮助。

 

7. 嵌入字体不当

如果处理不当,字体会影响加载性能。不要导入太多字体样式或粗细;只加载您需要的字体。

 

8. 未抽象元素以实现可重用性

不要为网站的每个部分硬编码元素或样式,而是创建可重用的组件和类。例如,如果您经常使用按钮,请创建一个基本按钮类,然后,在需要按钮的任何地方应用此类,而不必每次都编写新样式。

 

9. 未充分利用 Flexbox CSS Grid

许多开发人员仍然依赖过时的布局技术(如浮动或手动边距)进行布局,而不是使用 Flexbox CSS Grid 等现代工具。这些工具使响应式设计和布局变得容易得多。

10. HTML 中使用大写字母,而不是 CSS

不要在 HTML 中直接使用大写字母(因为以后无法轻易修改),而是使用 CSS 控制文本转换,这使得您的内容能够灵活地适应未来的变化。

 

通过避免这些常见错误,您可以确保您的网站更高效、更易于维护并提供更好的用户体验。
