一、引言
Web前端針對圖片顯示的優(yōu)化方案是當今web應用中最重要的部分,它可以幫助我們提升網(wǎng)站性能和體驗。在這個時代,人們已經(jīng)習慣于使用各種多媒體內(nèi)容來表達自己的想法,而圖片作為其中最重要的一部分,正在不斷受到大眾關注。然而,如果不通過合理的優(yōu)化方案讓圖片顯示得更好,就很難真正發(fā)掘出圖片所帶來的效益。

10余年的華州網(wǎng)站建設經(jīng)驗,針對設計、前端、開發(fā)、售后、文案、推廣等六對一服務,響應快,48小時及時工作處理。成都全網(wǎng)營銷的優(yōu)勢是能夠根據(jù)用戶設備顯示端的尺寸不同,自動調(diào)整華州建站的顯示方式,使網(wǎng)站能夠適用不同顯示終端,在瀏覽器中調(diào)整網(wǎng)站的寬度,無論在任何一種瀏覽器上瀏覽網(wǎng)站,都能展現(xiàn)優(yōu)雅布局與設計,從而大程度地提升瀏覽體驗。創(chuàng)新互聯(lián)公司從事“華州網(wǎng)站設計”,“華州網(wǎng)站推廣”以來,每個客戶項目都認真落實執(zhí)行。
二、Web前端針對圖片顯示的優(yōu)化方案講解
1. 壓縮圖片大小
將原始大小的圖片壓縮成適合視覺效果要求并且文件大小也能夠保證流暢加載速度。例如使用JPEG格式來存儲彩色團體,PNG格式存儲單一顏色或者GIF格式存儲加上alpha 通道(Alpha Channel) 的彩色/單一顏 色 團體, 來減少文件大小; 使用CSS3 Sprites 技術將多個icon/image 合并成一個sprite sheet , 然后再通過background-position CSS 屬性來實 現(xiàn)快速加 載; 使用SVG (Scalable Vector Graphics) 來代 替 PNG / JPEG / GIF 等 bitmap image format . SVG 本 貿(mào)是 XML based vector image format , 高度可擴展 , 大 多數(shù)海貍海貍都去得到其支 政 ;
2. 高效資源請求
避免重復請求相同URL ;避免HTTP 302 redirects ;避免DNS Lookup ?overhead ?by using CDN (Content Delivery Network); Use HTTP Cache to reduce the number of requests and improve loading speed; Use Gzip compression to compress resources before sending them over the network.
3. Web Font Optimization
Use web fonts instead of images for text elements on your website; Preload web fonts with tag in HTML head section or use JavaScript preloading technique to make sure that font is loaded before it’s used by browser; Minify font files and optimize their size as much as possible.
4. Image Lazy Loading
Lazy loading is a technique which defers loading of non-critical resources at page load time until they are needed later during user interaction with the page, such as scrolling down or hovering over an element etc.; This helps us save bandwidth and improve performance by only downloading necessary resources when they are actually required by user instead of downloading all assets upfront at page load time itself.
5. Responsive Images
Responsive images allow us to serve different versions of same image depending upon device type, viewport size etc., thus saving bandwidth and improving performance on mobile devices where connection speeds can be slow compared to desktop computers.; We can also use srcset attribute along with sizes attribute in img tag so that browser can decide which version of image should be downloaded depending upon device type & viewport size automatically without any manual intervention from our side.; We can also use picture element along with source tags inside it for more control over responsive images implementation if we need it..
