css filter滤镜的实例讲解_html/css_WEB-ITnose
由于 css3 的filter滤镜可以实现对对普通图像和SVG图像进行特效渲染,功能十分强大,所以今天特意把filter滤镜的用法进行大致的总结
语法:
element { filter: none | <filter-function > [ <filter-function> ]* } <img class="grayscale lazy" src="/static/imghw/default1.png" data-src="image.jpg" style="max-width:90%" style="max-width:90%" alt="css filter滤镜的实例讲解_html/css_WEB-ITnose" >.grayscale { filter: graycale(1); //灰度属性 //可填写范围0~1,默认值为0,即灰度不改变}
上面介绍了第一种滤镜: grayscale(灰度)
下面介绍接下来的九种滤镜
2.blur()高斯模糊
使用:该方法将周围像素点值求和取平均即为该点像素值参数:此属性接受参数接受长度值,默认值为0
.blur { filter: blur(1px)}
效果:
3.brightness()亮度
使用: 该方法调节图片的亮度参数: 默认值为1,但所填写值可以大于1,此时图像亮度会继续增强
.brightness { filter: brightness(0.6)}
效果图:
4.contrast对比度
使用: 通过调节对比度使亮处更亮,暗处更暗参数: 默认值为1,最小值为0,无最大值
.contrast{ filter: contrast(150%)}
效果图:
5.drop-shadow设置阴影
使用: 使用效果与box-shadow类似,但浏览器可能会提供加速参数: 第一二个值是偏移量(允许负值) , 第三个参数表示模糊程度(不允许负值),第四个参数表示颜色
.drop-shadow{ filter: drop-shadow(20px, 20px, 10px, black)}
效果图:
6.hue-rotate色相
使用: 用于改变色相(即具体像素的数值)参数: 用角度表示,当数值为360deg时,图像不变
.hue-rotate{ filter: hue-rotate(90deg)}
效果图:
7.invert()图像反转
使用: 对图像进行颜色上的反转参数: 默认值是0,最大值是1
.invert{ filter: invert(100%)}
效果图:
8.opacity透明度
使用: 此样式类似于opacity属性参数: 0%~100%
.opacity { filter: opacity(50%) }
效果图:
9.saturate()饱和度
使用: 转换图像饱和度参数: 默认值是100%, 但超过100%的值是允许的
.saturate{ filter: saturate(200%)}
效果图:
![ 图片描述][9]
10.sepia褐色加深(会产生一种老照片的感觉)
使用: 将图像转换为褐色参数: 默认值为0,范围是0~1
.sepia{ filter: sepia(100%)}
效果图
11.进行图像的复合处理,可以对图像进行任意的组合以获得想要的结果
.mixture{ filter:brightness(1.2) contrast(1.2)}
效果图:
通过filter属性你可以把你喜欢的图片非常容易地修改成易用的样式
......往往会把一件完整的东西化成无数的形象,就像凹凸镜一般,从正面望去,只见一片模糊.

HTML is suitable for beginners because it is simple and easy to learn and can quickly see results. 1) The learning curve of HTML is smooth and easy to get started. 2) Just master the basic tags to start creating web pages. 3) High flexibility and can be used in combination with CSS and JavaScript. 4) Rich learning resources and modern tools support the learning process.

HTML defines the web structure, CSS is responsible for style and layout, and JavaScript gives dynamic interaction. The three perform their duties in web development and jointly build a colorful website.

HTML, CSS and JavaScript are the three pillars of web development. 1. HTML defines the web page structure and uses tags such as, etc. 2. CSS controls the web page style, using selectors and attributes such as color, font-size, etc. 3. JavaScript realizes dynamic effects and interaction, through event monitoring and DOM operations.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.

The roles of HTML, CSS and JavaScript in web development are: HTML is responsible for content structure, CSS is responsible for style, and JavaScript is responsible for dynamic behavior. 1. HTML defines the web page structure and content through tags to ensure semantics. 2. CSS controls the web page style through selectors and attributes to make it beautiful and easy to read. 3. JavaScript controls web page behavior through scripts to achieve dynamic and interactive functions.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.
