As a website operator who deeply understands the operation of AnQiCMS, I know that ensuring that website images can be displayed responsively in today's multi-device environment is crucial for improving user experience, optimizing search engine rankings, and maintaining the professional image of the brand.AnQiCMS as an efficient and flexible content management system, provides a variety of built-in features and flexible template mechanisms, enabling us to effectively achieve this goal.

Responsive Design Basics of AnQiCMS

AnQiCMS at the beginning of system design considered the needs of multi-terminal access, its website mode supports three types of 'adaptive', 'code adaptation', and 'PC+mobile independent site'.This lays a foundation for us to handle responsive image display.

“Auto” mode means that the website template itself will automatically adjust the layout and element sizes according to the device screen size, and the images also need to match this flexible layout. In this mode, the front-end CSS rules are the key to implementing image responsiveness, such as settingimg { max-width: 100%; height: auto; }Ensure that the image does not overflow the container and maintains the aspect ratio.

The "Code Adaptation" mode allows the server to determine the device type and then load different HTML structures or CSS styles.This means we can provide different image URLs or sizes for different devices.

“PC+mobile independent site” mode is the most direct, allowing for completely independent template and content structures for PC and mobile ends. In this case, we can specifically upload, optimize, and call smaller images for mobile sites, which are stored inmobileThe template corresponding to the directory.

Using AnQiCMS image optimization feature

The background content settings of AnQiCMS provide powerful image processing capabilities, which is the core link to ensure responsive image display.

Firstly,WebP image formatThe enable is an effective means to improve loading speed.In the background's “Content Settings”, we can choose whether to enable the Webp image format.Once enabled, AnQiCMS will automatically convert the uploaded images to WebP format after uploading, which can significantly reduce file size while maintaining high quality, thereby accelerating the loading speed of pages on various devices. It greatly enhances the user experience, especially under mobile network environments.

Secondly,Automatic compression of large imagesThe feature helps us manage the size of the original images uploaded.In the "Content Settings", we can enable the "Whether to automatically compress large images" and set the "Automatic compression to a specified width", such as 800 pixels.This means that even if the operation personnel upload high-resolution large images, the system can automatically resize them to a reasonable size, avoiding unnecessary bandwidth consumption and rendering burden, which is particularly important for mobile devices.

Moreover,Thumbnail processing method and sizeFine control is the key to responsive image display.AnQiCMS provides "scale proportionally by the longest sideThese predefined thumbnail sizes can be flexibly called in the template.item.Thumb）；For the detail page, you can call larger-sized images (such asitem.Logo) or the original size). The existence of multiple image sizes provides the frontend with more advanced responsive image technology (such assrcsetand<picture>Label）provided the possibility.

Image responsive implementation at the template level.

In AnQiCMS template files, we can combine the system-provided image function to achieve responsive image display on multiple devices.

The most basic and universal method is to add style rules for images in CSS, for example:

img {
    max-width: 100%; /* 确保图片不会超出其容器 */
    height: auto;    /* 保持图片的宽高比 */
    display: block;  /* 消除图片底部默认间隙 */
}

This allows the image to adjust its size to different screen sizes.

For more precise control, we can use images of different sizes generated by AnQiCMS. In the template, you can call images usingarchiveDetailorcategoryDetailtags.Logo(usually the cover image),Thumb(Thumbnail) or throughImagesTag to get a list of images. Combined with HTML5'ssrcsetproperties, we can let the browser select the most appropriate image based on the device's pixel density and viewport size:

<img srcset="{{ item.Thumb }} 480w, {{ item.Logo }} 800w, {{ item.Images[0] }} 1200w"
     sizes="(max-width: 600px) 480px, (max-width: 900px) 800px, 1200px"
     src="{{ item.Logo }}" alt="{{ item.Title }}">

Although AnQiCMS does not generate code directlysrcsetbut it provides multiple size image sources, allowing us to manually construct such structures at the template level.

Additionally, AnQiCMS intag-/anqiapi-archive/142.htmlas mentioned in the content fieldContentSupport image lazy loading (lazy="data-src") This means that images can be displayed in templatessrcattribute in the content withdata-src，coinciding with the front-end JavaScript library to implement image loading when they scroll into the visible area, which greatly optimizes the initial page loading speed, especially important for mobile user experience.

For websites adopting the "code adaptation" or "PC+mobile independent site" model,design-convention.mdmentionedmobileThe catalog, we can create a set of templates specifically for mobile devices.In this template, you can call smaller, lighter image resources, and even adjust the layout of the images to provide an optimized mobile experience.

operational strategy and SEO advantages

Ensure that the image is responsive across multiple devices, which not only improves the user experience of the website but also has a significant advantage for SEO.The search engine will prioritize loading websites with fast speed and good user experience.Optimized images can reduce page loading time, decrease bounce rate, and improve conversion rate.At the same time, through the background image watermark and anti-crawling function, it can also effectively protect the copyright of original images and ensure the exclusivity of the content.

In summary, AnQiCMS provides full-chain support from image upload processing to flexible template usage, enabling website operators to easily achieve perfect responsive display of images on different devices through reasonable backend configuration and template development.This not only optimizes the user experience, but also lays a solid foundation for the long-term development of the website and SEO performance.

Common Questions and Answers (FAQ)

1. Why does the image still look blurry or load slowly on mobile even though I have set image compression and WebP in the background?

This usually has several reasons.Firstly, make sure that the quality of the original image you upload is high enough. If the original image is already very small or blurry, even converting it to WebP and compressing it, the effect is limited.其次，Check whether your frontend template correctly calls the thumbnails or optimized images generated by AnQiCMS.Sometimes, the template may still refer to the unoptimized original image URL.Additionally, if your website has CDN (Content Delivery Network) enabled, make sure the CDN configuration is correct and the cache is updated so that users can access the latest, optimized image resources.

2. AnQiCMS是否会自动为我的图片生成Englishsrcset属性，以实现真正的响应式图片？English

These features provide for responsive images.Images of various sizesHowever, AnQiCMS does not automatically generate in HTML includingsrcsetandsizesThe code of the property. You need to manually write HTML code and combine it with the different size image links provided by AnQiCMS to build a template.srcsetProperties responsive image. For example, using{{item.Thumb}}and{{item.Logo}}tags to fill insrcsetdifferent image URLs.

3. How should I balance image quality and loading speed? Are there any recommended settings?

Balancing image quality and loading speed is the core of responsive image optimization. The recommended approach is:

  • Enable WebP formatThis is the most direct optimization method built-in to AnQiCMS, which can greatly reduce the file size.
  • Enable automatic compression of large images.：Set the 'Auto-compress to specified width' to a commonly used maximum display width, such as 1920px or 1200px, to avoid loading overly large images.
  • Reasonable thumbnail size settingsEnglish: According to the page layout and content display requirements, set a reasonable thumbnail size in 'Content Settings'.For example, the list page uses small thumbnails (such as 300x200), and the embedded images on the article detail page are set according to the width of the article content (such as 800px).
  • Combined with lazy loading: Add lazy loading attributes to images in the template (such aslazy="data-src"Ensure that images are only loaded when they enter the user's visible area, further improving the speed of the first screen load.
  • Monitoring and adjustmentRegularly use tools such as Google PageSpeed Insights to test website performance, and adjust image settings and template code according to the report feedback.
