在互联网时代,网站是面向网民户的第一道门,用户经常通过搜索引擎搜索相关内容,进入到相关网站或者企业官网,这个时候网站的打开速度就显得尤为重要。网站打开速度往往是企业建站过程中最关心的问题,网站打开速度慢,不仅会影响用户体验,甚至会导致我们丢失大量的客户,所以优化网站制作提高网站打开速度,是网站制作过程中一项重要的工作。

In the Internet age, the web site is the first door for Internet users. Users often search for related content through search engines and enter related websites or business websites. At this time, the opening speed of the website is particularly important. The opening speed of the website is often the most concerned problem in the process of building the enterprise. The slow speed of the website will not only affect the user experience, but also cause us to lose a large number of customers.

一、将网站图片尺寸截取到尽量小
First, the size of the picture of the website is truncated as small as possible
在网站制作过程中,我们通常会限制图片的额限制区域,为图片指定一个显示尺寸,但一般上传的都会比该尺寸要大,甚至导致图片变形、模糊等问题,影响打开速度。
In the process of making the website, we usually limit the limit area of the picture and specify a display size for the picture, but the general upload will be larger than that of the size, even the distortion and blurring of the picture and so on, which affects the opening speed.
二、将网站图片体积压缩到尽量小
Two, compress the volume of the web site to as small as possible
字节数大小是网站打开中最直接影响网站加载时间的,网站为了图文并茂,通常会加入许多图片,单独的图片还能够接受,但当图片多的时候,就会影响打开速度。故而应该在保证图片质量的同时,尽量压缩图片字节,通过这项工作基本上可以把网站速度提高一倍。
The size of the number of bytes is the most direct impact on the site of the site to load time. In order to map and text, the site usually adds a lot of pictures, and a single picture can be accepted, but when the picture is more, it will affect the opening speed. Therefore, the picture byte should be compressed as much as possible while ensuring the quality of the picture. This work can basically double the speed of the website.
三、将网站图片数量尽量减少
Three, reduce the number of pictures of the website as much as possible
网站图片作为网站打开速度优化的重要对象,将网站图片进行合并,使网站图片数量尽量少能够大大提高网站打开速度。这也是不少人在建网站时,尽量避免的问题。网站页面的资源数量多少不仅影响网站的资源的加载时间,也影响网站资源的DNS请求时间,所以对网站资源的合并对提高网站打开速度是非常重要的。主要方法就行对网站图标、背景等图片进行CSS贴图处理。
As an important object of Web site opening speed optimization, website pictures are merged to make the number of websites as few as possible to greatly improve the speed of the website. This is also a problem that many people try to avoid when building websites. The number of web pages not only affects the time of the site's resource loading, but also affects the DNS request time of the website resources, so it is very important to combine the resources of the website to improve the speed of the website. The main method is to conduct CSS map processing on website icons, backgrounds and other pictures.
四、将网站制作图片进行延迟加载
Four. Delay loading the website by making pictures
当一个网站有许多图片时,很多是不需要在第一时间呈现给用户的,所以通常不在第一屏显示的图片,可以对这些图片进行延迟加载,让需要第一时间显示的图片更快的加载和显示给客户。
When a web site has many pictures, many are not required to be presented to the user at the first time, so they are usually not displayed on the first screen, and can be delayed to load the pictures so that the pictures that need the first time display are loaded and displayed to the customers faster.
