About the situation and solution that the HTML font appears blurred and the font becomes normal after clicking
The problem just appeared on the page:
After clicking the font, it becomes normal:
Reasons and solutions:
Because the development is using the Blue Lake, the styles are copied directly, and this style attribute of the background CSS causes ghosting:
/* 使背景模糊 */
backdrop-filter: blur(8.1px);
After removing it, it will be normal. Friends in similar situations can check whether this attribute works.
