When designing websites, you need to use images frequently to create engaging and informative content for your visitors. However, when you need to use the same image in different places on the site, the problem of duplicating code and loading the image several times arises.

In CSS, there are several simple ways to get rid of duplicate images and reduce page load time. One such way is to use sprites. A sprite is a single image that contains various parts used by a website. This way, instead of downloading multiple files, the browser will only download one image.

Another way is to use the data-uri tag , which allows you to embed the image directly into the CSS code. This way, there is no need to download the image separately, which speeds up the page loading process.

Using the before or after tag can also add an image in CSS without duplicating the code. This is especially useful when you need to add a background image or icons to web page elements. Instead of creating a separate class for each element, you can use pseudo-elements to add an image without any extra code.

**Duplicate image problem in CSS**

One common problem with CSS is duplicate images. Duplicate images can occur in cases where the same image is used several times on a page, but it is loaded separately each time. This may result in increased page load times and suboptimal resource utilization.

Duplicate images in CSS can be caused by various factors. For example, when creating different classes that assign the same image as the background, each time the class is used, the image load is duplicated.

Another reason for duplicate images could be the suboptimal use of pseudo-elements such as :before and :after. When using pseudo-elements with a background image, the image will also be duplicated each time the pseudo-element is used.

Duplicating an image in CSS can cause unnecessary load on the server and slow down page loading. The optimal solution to the problem of image duplication is to use special methods and approaches that avoid re-downloading the image and optimize the use of resources.

**Minimizing site load**

One of the basic principles of creating a fast website is to minimize its load. The smaller the page size and the number of downloaded resources, the faster the user will access the content. In this article, we'll look at some ways to minimize website load.

**Image optimization**

One of the most effective ways to reduce page size is to optimize your images. You can use special tools such as [Adobe Photoshop for editing ](https://prophotoshopexpert.com/)or online services to reduce the size of image files without losing their quality.

**CSS and JavaScript compression**

Another way to reduce page size is to compress CSS and JavaScript files. You can use various tools like YUI Compressor or UglifyJS to remove extra spaces, comments, and other unnecessary characters from CSS and JavaScript files.

Another way to reduce the number of downloaded resources is to combine files. You can combine all CSS and JavaScript files into one to reduce the number of requests to the server. You can also use special tools such as Gulp or Grunt to automatically combine and minify files.

**Using caching**

Caching is the process of storing copies of resources on a user's computer. When you visit the site again, the browser can use these saved copies instead of downloading them again. You can configure caching for different file types using special HTTP headers.

**Reducing the number of HTTP requests**

The number of HTTP requests it takes to load a page matters a lot. The fewer requests, the faster the page will load. You can reduce the number of HTTP requests by concatenating files, using sprites for images, or embedding small files directly in the HTML code.

**Using external hosting**

If you have files such as JavaScript libraries or fonts that are used across multiple pages of your site, you can host them on external hosting such as a CDN . This will help speed up page loading and reduce the load on your server.

Connecting scripts at the bottom of the page

To prevent page rendering from being blocked, it is recommended to place scripts at the bottom of the page, below the content. This way, the page will load and be displayed to the user faster.
