1. It is difficult to implement adaptive layout

In responsive design, we usually hope that elements can be adaptively laid out according to the screen size and orientation of different devices. However, when using the display attribute, you often need to manually control the display mode of elements through media query or JavaScript, which increases the complexity of development and the difficulty of maintenance.

2. Impact on document flow

When we set the display attribute of an element to a non-default value, such as setting the display attribute to "inline-block" or "inline", it will cause the element to Convert block-level elements to inline elements. This can disrupt the original flow of the document, causing elements to be disorganized and arranged in a disorganized manner.

3. Not good for SEO

Search engine optimization (SEO) is very important for the visibility of the website. However, when using the display attribute, you may hide certain elements or change the layout of elements, which will affect the search engine's parsing and ranking of web pages. Therefore, when using the display attribute, you need to handle it with caution to avoid negatively affecting the visibility and accessibility of the web page.

4. May cause performance problems

Some display values, such as "none" and "hidden", will cause the element to be completely hidden and not occupy layout space. However, when there are a large number of such hidden elements in the page, it can have a negative impact on performance. Because the browser still needs to handle the layout and rendering of these hidden elements, and the event listeners of hidden elements will still be triggered, this will increase the burden on the browser.

5. Compatibility issues

Different browsers may have different support and expression methods for the display attribute, which may cause the page to display inconsistently on different browsers. Especially when dealing with some older versions of browsers, additional compatibility processing is required, which increases the development workload.

In summary, although the display attribute has certain flexibility and functionality in front-end development, it also has some disadvantages. Developers need to consider carefully when using the display attribute and comprehensively weigh various factors to achieve the best user experience and development efficiency.
