Apr 05, 2025 pm 05:36 PMClever solution: Text gradient shadow conflicts with grandfather element background
In web design, it is very common to create text gradients and shadows using pseudo-elements, but sometimes you encounter the problem of grandfather elements occluding pseudo-elements in the background. This article will analyze this problem in depth and provide effective solutions.
First, let's look at a typical code example, which can implement text gradients and shadows:
<div class="header"> <p class="text" data-text="示例文本">Sample text</p> </div>
.header { width: 100%; height: 100px; /* Adding background color here will block pseudo-elements*/ background-color: #f0f0f0; } .text { -webkit-text-fill-color: transparent; background-image: linear-gradient(to bottom, red 0%, green 100%); -webkit-background-clip: text; background-clip: text; font-size: 40px; font-weight: bold; letter-spacing: 9px; } .text::before { content: attr(data-text); position: absolute; color: transparent; text-shadow: 0 4px 2px blue; z-index: -1; /* Negative z-index value is invalid*/ }
When adding background color to the .header
element, pseudo-element ::before
will be obscured. This is because of the stacking contextual nature of pseudo-elements. Simply put, although a pseudo-element is visually attached to the parent element, it is at the same level as other child elements of the parent element in the stacking order. Even if a negative z-index
is set, it cannot be left behind the grandfather element background.
Solution: Adjust the stacking context
To solve this problem, we need to upgrade the cascaded context of the .text
element and its pseudo-elements so that it is higher than the background of the grandfather element. Just simply add position: relative;
and a positive z-index
value to the .text
element:
.text { position: relative; z-index: 1; /* Improve the stacking order*/ -webkit-text-fill-color: transparent; background-image: linear-gradient(to bottom, red 0%, green 100%); -webkit-background-clip: text; background-clip: text; font-size: 40px; font-weight: bold; letter-spacing: 9px; }
With this modification, the .text
element and its pseudo-element will be correctly rendered on the background of the grandfather element, thus solving the occlusion problem. This is a simple and effective solution without complex cascading context operations.

The steps for troubleshooting and repairing Redis master-slave replication failures include: 1. Check the network connection and use ping or telnet to test connectivity; 2. Check the Redis configuration file to ensure that the replicaof and repl-timeout are set correctly; 3. Check the Redis log file and find error information; 4. If it is a network problem, try to restart the network device or switch the alternate path; 5. If it is a configuration problem, modify the configuration file; 6. If it is a data synchronization problem, use the SLAVEOF command to resync the data.

The quick location and processing steps for Redis cluster node failure are as follows: 1. Confirm the fault: Use the CLUSTERNODES command to view the node status. If the fail is displayed, the node will fail. 2. Determine the cause: Check the network, hardware, and configuration. Common problems include memory limits exceeding. 3. Repair and restore: Take measures based on the reasons, such as restarting the service, replacing the hardware or modifying the configuration. 4. Notes: Ensure data consistency, select appropriate failover policies, and establish monitoring and alarm systems.

Redis and RabbitMQ each have their own advantages in performance and joint application scenarios. 1.Redis performs excellently in data reading and writing, with a latency of up to microseconds, suitable for high concurrency scenarios. 2.RabbitMQ focuses on messaging, latency at milliseconds, and supports multi-queue and consumer models. 3. In joint applications, Redis can be used for data storage, RabbitMQ handles asynchronous tasks, and improves system response speed and reliability.
