Article Introduction：z-index works in CSS with a dependency on positioning and stacking context and cannot be effective alone. Elements must be positioned in relative, absolute, fixed or sticky before using z-index; 1. Elements in different stacking contexts will not directly compare z-index values; 2. The stacking context is created by the root element, positioning elements with z-index set, etc.; 3. Common problems such as the menu is blocked, it can be solved by improving the z-index of the entire container; 4. The modal box should be placed under the body to avoid nesting in low-level contexts; 5. The hierarchy range should be planned instead of abuse of high numerical values, such as UI overlay layer 1000, modal box 2000, prompt 3000, notification 4000. reason

Article Introduction：To solve the problem of overlapping web elements, we must first understand CSS positioning and z-index attributes. 1. The positioning type of element determines its layout in the page, such as static, relative, absolute, fixed and sticky, each has different behaviors; 2. z-index controls the stacking order of elements, but is only valid for positioning elements and is subject to the stacking context; 3. In actual repair, position:absolute and higher z-index must be set by the pull-down menu. The background color should be added to the fixed head and the top margin should be added to the content area. The modal box should use position:fixed and higher z-index, and the overlap between absolute positioning elements should be adjusted by adjusting z

Article Introduction：The inert attribute is a boolean attribute in HTML that is used to make elements and their children not interactable. It prevents keyboard focus from entering, disables mouse clicks and makes screen readers ignore these contents. It is suitable for blocking background content when the modal box pops up, disabling area of the page function without completion, and placeholding before dynamic loading. When using it, you need to pay attention to compatibility issues to avoid abuse, and it cannot replace the disabled attribute. JavaScript can dynamically control inert properties, such as setting modalBackground.inert=true/false to switch regional interaction status, thereby improving the barrier-free experience of web pages and user operation accuracy.

Article Introduction：You cannot directly access custom payment channels through H5's PaymentRequestAPI, but you can achieve a similar experience through simulation. 1. Understand that PaymentRequestAPI is designed for the browser's built-in payment methods, such as GooglePay and ApplePay, which does not support directly registering a custom payment gateway; 2. If a custom payment method name is passed in (such as 'my-custom-gateway'), most browsers will ignore or report an error; 3. By imitating the UI and custom logic, you can create a modal box to simulate payment pop-up window to guide users to select payment methods; 4. After confirming, the user calls his own back-end interface or jumps to the payment page to complete the payment process; 5. In addition, the front-end group can be used.

Article Introduction：Using slots and named slots in Vue can improve component flexibility and reusability. 1. The slot allows the parent component to insert content into the child component through a tag, such as inserting paragraph text into the Card.vue component; 2. The named slot realizes control of the content insertion position through the name attribute, such as defining the header, body and footer areas respectively in the modal box component; 3. The default content can be set in the slot as an alternative when the parent component is not provided, such as the default close button; 4. The # symbol is the abbreviation syntax of v-slot:; 5. It is recommended to use slots reasonably to avoid excessive dependence, and some content can be considered to be implemented through props or scope components.

Article Introduction：When managing HTML keyboard focus using the tabindex attribute, you should prioritize natural order and ensure accessibility. First, understand the three valid values ​​of tabindex: 0 means that it can be focused in the order of the document; -1 means that it can only be focused through scripts; positive numbers mean custom focus order (not recommended). Second, add tabindex="0" and appropriate ARIA roles to non-form elements for keyboard access. Third, avoid using high positive values ​​to disrupt the natural order, and the order should be controlled by adjusting the HTML structure. Fourth, use tabindex="-1" when you need to control the focus of the program, such as automatic focus after the modal box is opened. Finally, always test the keyboard navigation to confirm

Article Introduction：The ineffectiveness of z-index is often due to the influence of the cascaded context. 1. The stacking context is the "space scope" of an element, and the stacking order of child elements is calculated independently; 2. The creation method includes setting positioning z-index, opacity is less than 1, transform, etc.; 3. z-index is only valid for positioning elements, and the levels cannot be directly compared when the parent-child level is in different contexts; 4. The browser comprehensively determines the stacking order based on the DOM order, positioning, layout method, etc.; 5. Practical problems such as the modal box is blocked, you need to check the context level and adjust the structure or z-index instead of blindly increasing the value.
