Preload key requests
Key requests can be preloaded by using '<link rel=preload>'. 123nhadatviet.com should consider using '<link rel=preload>' to prioritize fetching resources that are currently requested later in page load.
Use video formats for animated content
Large GIFs are inefficient for delivering animated content. It is recommended to use MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF.
Remove duplicate modules in JavaScript bundles
Ensure that no duplicate JavaScript modules from bundles exist to reduce bytes consumed by network activity.
Avoid serving legacy JavaScript to modern browsers — Potential savings of 24 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. For bundled JavaScript it is recommended to adopt a modern script deployment strategy using module/nomodule feature detection. This will reduce the amount of code shipped to modern browsers.

Accessibility

Indicates how accessible the page is and highlights opportunities where the page can be made more accessible to users of 123nhadatviet.com. This includes details about various page attributes that can be optimized.

Navigation

`[accesskey]` values are unique
Access keys assist users with focusing on different parts of the page. Each access key should be unique for proper navigation.
The page contains a heading, skip link, or landmark region
It is advised to provide ways to bypass repetitive content, allowing users to navigate the page efficiently.
`[id]` attributes on active, focusable elements are unique
Ensure all focusable elements have a unique id value to allow them to be visible to users of assistive technologies, like a screen reader.
Heading elements appear in a sequentially-descending order
Properly order all headers and do not skip heading levels to better the navigation and readability for users of assistive technologies, like a screen reader.
No element has a `[tabindex]` value greater than 0
Although technically valid, a tabindex value greater than 0 often creates frustrating experiences for users who rely on assistive technologies.

ARIA

`[aria-*]` attributes match their roles
Avoid mismatching 'aria-*' attributes and their 'role' value, as it invalidates the attribute.
`button`, `link`, and `menuitem` elements have accessible names
Without accessible names on elements, screen readers will default to announcing a generic name, which means your content will be less accessible to users who rely on screen readers.
`[aria-hidden="true"]` is not present on the document `<body>`
If aria-hidden=true is set on the document body, assistive technologies, like a screen reader will work inconsistently.
`[aria-hidden="true"]` elements do not contain focusable descendents
Interactive elements within an aria-hidden=true element are unavailable to users of assistive technologies, like a screen reader.
ARIA input fields have accessible names
Generic names are announced to users of assistive technologies, like a screen reader, when an input field does not have an accessible name specified.
ARIA `meter` elements have accessible names
Without accessible names on elements, screen readers will default to announcing a generic name, which means your content will be less accessible to users who rely on screen readers.
ARIA `progressbar` elements have accessible names
Without accessible names on elements, screen readers will default to announcing a generic name, which means your content will be less accessible to users who rely on screen readers.
`[role]`s have all required `[aria-*]` attributes
Some ARIA roles have required 'aria-*' attributes, which provide essential information about state and functionality.
Elements with an ARIA `[role]` that require children to contain a specific `[role]` have all required children.
Some ARIA parent roles cannot perform their intended functions if specific child roles are not used.
`[role]`s are contained by their required parent element
Some ARIA child roles cannot perform their intended functions if specific parent roles are not used.
`[role]` values are valid
All ARIA roles require valid values to perform their intended functions.
ARIA toggle fields have accessible names
Generic names are announced to users of assistive technologies, like a screen reader, when a toggle field does not have an accessible name specified.
ARIA `tooltip` elements have accessible names
Without accessible names on elements, screen readers will default to announcing a generic name, which means your content will be less accessible to users who rely on screen readers.
ARIA `treeitem` elements have accessible names
Without accessible names on elements, screen readers will default to announcing a generic name, which means your content will be less accessible to users who rely on screen readers.
`[aria-*]` attributes have valid values
ARIA attributes cannot be interpreted with invalid values when used by screen readers and other assistive technologies.
`[aria-*]` attributes are valid and not misspelled
ARIA attributes cannot be interpreted with invalid names when used by screen readers and other assistive technologies.
ARIA IDs are unique
Ensure all ARIA ID values are unique to prevent elements from being overlooked by assistive technologies, like a screen reader.

Names and labels

Buttons have an accessible name
Buttons become unusable as they are announced simply as "button" when the button does not have an accessible name, when used by screen readers and other assistive technologies.
Document has a `<title>` element
Search engines, screen reader users and other assistive technology users rely on the title to provide an overview of the page and to help determine if the page is relevant to their search.
No form fields have multiple labels
Having multiple labels for form fields can be confusing to assistive technologies, like a screen reader.
`<input type="image">` elements have `[alt]` text
Input buttons with alternative text assist screen readers and other assistive technology users to understand its purpose.
Form elements have associated labels
Screen readers and other assistive technologies rely on labels to properly announce form controls.
`<object>` elements have `[alt]` text
It is advised that alt text is used on '<object>' elements in order to provide meaning to screen reader and other assistive technology users, as these technologies are unable to translate non-text content.

Tables and lists

`<dl>`'s contain only properly-ordered `<dt>` and `<dd>` groups, `<script>`, `<template>` or `<div>` elements.
Screen readers and other assistive technologies may produce poor and inaccurate output when definition lists are not properly marked up.
Definition list items are wrapped in `<dl>` elements
In order for screen readers and other assistive technologies to properly announce definition list items ('<dt>' and '<dd>'), they must be wrapped in parent a '<dl>' element.
List items (`<li>`) are contained within `<ul>` or `<ol>` parent elements
In order for screen readers to announce list items, ensure that list items ('<li>') are contained within parent '<ul>' or '<ol>' tags.
Cells in a `<table>` element that use the `[headers]` attribute refer to table cells within the same table.
Screen readers and other assistive technologies have features to make navigating tables easier. Ensure that '<td>' cells using the headers attribute only refer to other cells in the same table, to improve screen reader user experience.
`<th>` elements and elements with `[role="columnheader"/"rowheader"]` have data cells they describe.
Screen readers and other assistive technologies have features to make navigating tables easier. Ensure that table headers refer to some set of cells, to improve screen reader user experience.

Internationalization and localization

`<html>` element has a valid value for its `[lang]` attribute
Specify a valid BCP 47 language in order to help screen readers and other assistive technologies announce text properly.
`[lang]` attributes have a valid value
Specify a valid BCP 47 language on elements in order to help screen readers and other assistive technologies announce text properly.

Best practices

The document does not use `<meta http-equiv="refresh">`
Pages that refresh automatically cause a poor user experience as focus is directed back to the top of the page unexpectedly.
`[user-scalable="no"]` is not used in the `<meta name="viewport">` element and the `[maximum-scale]` attribute is not less than 5.
For users with low vision who rely on screen magnification, ensure that zooming is not disabled.

Audio and video

`<video>` elements contain a `<track>` element with `[kind="captions"]`
123nhadatviet.com may provide assistance to deaf or hearing-impaired users with captions on videos.

Contrast

Background and foreground colors do not have a sufficient contrast ratio.
Many (if not most) users find low-contrast text difficult or impossible to read.

SEO

Indicates how well the page is optimized for ranking in search engines and highlights Search Engine Optimization (SEO) opportunities for 123nhadatviet.com. This includes optimizations such as providing meta data.

Content Best Practices

Document has a `<title>` element
Search engines, screen reader users and other assistive technology users rely on the title to provide an overview of the page and to help determine if the page is relevant to their search.
Document has a meta description
Meta descriptions may be used by search engines when displaying a link to the page and should concisely summarize the page's content.
Links have descriptive text
Make use of descriptive link text to assist search engines in understanding the content.
Document has a valid `hreflang`
Search engines can be instructed to list specific versions of a page for a given language or region through the use of hreflang links.
Document has a valid `rel=canonical`
Search engines can be suggested which URL should be shown in search results through the use of canonical links.
Document avoids plugins
The content of plugins cannot be indexed by search engines and many devices either restrict or do not support them.

Crawling and Indexing

Page has successful HTTP status code
Avoid pages with unsuccessful HTTP status codes as they may not be indexed by search engines.
Links are crawlable
Ensure that the 'href' attribute of anchor elements links to the appropriate destination. This allows for more pages of the site to be discovered by search engines.
Page isn’t blocked from indexing
Pages that cannot be crawled by search engines cannot be indexed or included in their search results. Ensure that search engines have permission to crawl all pages that should be indexed.
robots.txt is valid
Malformed robots.txt files prevent crawlers from understanding how a site wants to be crawled or indexed, which can be devastating to SEO.

Mobile Friendly

Document uses legible font sizes
Font sizes of 12px or less are too small to most mobile users without user gestures and further action. Aim for more than 60% of page text to use font sizes greater than 12px.
Tap targets are sized appropriately
Interactive elements (such as buttons and links) should be appropriately spaced, sized and easy enough to select or tap with regard to their surrounding elements.

Mobile Friendly

Does not have a `<meta name="viewport">` tag with `width` or `initial-scale`
It is advised to use a '<meta name="viewport">' tag for the optimization of 123nhadatviet.com on mobile screens.

First Contentful Paint (3G) — 3204 ms
The time taken for the first image or text on the page to be rendered while on a 3G network.

Opportunities

Properly size images
Images can slow down the page's load time. 123nhadatviet.com should consider serving more appropriate-sized images.
Defer offscreen images
Time to Interactive can be slowed down by resources on the page. 123nhadatviet.com should consider lazy-loading offscreen and hidden images.
Minify CSS
Cascading Style Sheets (CSS) files can contribute to network payload sizes. 123nhadatviet.com should consider minifying CSS files.
Minify JavaScript
JavaScript (JS) files can contribute to network payload sizes and increase script parse times. 123nhadatviet.com should consider minifying JS files.
Remove unused CSS
Dead and/or unused rules in Style Sheets (CSS) can contribute to network payload sizes. 123nhadatviet.com should consider removing dead rules from style sheets and deferring the loading of CSS not used for above-the-fold content.
Efficiently encode images
Unoptimized images can consume more cellular data than what is necessary.
Serve images in next-gen formats — Potential savings of 11 KiB
Image formats like PNG and JPEG have poor compression when compared to other next-gen formats, such as JPEG 200, JPEG XR and WebP.
URL Resource Size (Bytes) Potential Savings (Bytes)

Enable text compression
Text-based resources should be served with compression, such as gzip, deflate or brotli.
Preconnect to required origins
Resource hints, such as 'preconnect' or 'dns-prefetch', may assist in establishing early connections to important third-party origins.
Avoid multiple page redirects — Potential savings of 630 ms
Redirects can cause additional delays before the page can begin loading. 123nhadatviet.com should avoid multiple or unnecessary page redirects.

Preload key requests
Key requests can be preloaded by using '<link rel=preload>'. 123nhadatviet.com should consider using '<link rel=preload>' to prioritize fetching resources that are currently requested later in page load.
Use video formats for animated content
Large GIFs are inefficient for delivering animated content. It is recommended to use MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF.
Remove duplicate modules in JavaScript bundles
Ensure that no duplicate JavaScript modules from bundles exist to reduce bytes consumed by network activity.
Avoid serving legacy JavaScript to modern browsers — Potential savings of 16 KiB
Polyfills and transforms enable legacy browsers to use new JavaScript features. For bundled JavaScript it is recommended to adopt a modern script deployment strategy using module/nomodule feature detection. This will reduce the amount of code shipped to modern browsers.

`[id]` attributes on active, focusable elements are unique
Ensure all focusable elements have a unique id value to allow them to be visible to users of assistive technologies, like a screen reader.
Heading elements appear in a sequentially-descending order
Properly order all headers and do not skip heading levels to better the navigation and readability for users of assistive technologies, like a screen reader.
No element has a `[tabindex]` value greater than 0
Although technically valid, a tabindex value greater than 0 often creates frustrating experiences for users who rely on assistive technologies.

ARIA

`[aria-*]` attributes match their roles
Avoid mismatching 'aria-*' attributes and their 'role' value, as it invalidates the attribute.
`button`, `link`, and `menuitem` elements have accessible names
Without accessible names on elements, screen readers will default to announcing a generic name, which means your content will be less accessible to users who rely on screen readers.
`[aria-hidden="true"]` is not present on the document `<body>`
If aria-hidden=true is set on the document body, assistive technologies, like a screen reader will work inconsistently.
`[aria-hidden="true"]` elements do not contain focusable descendents
Interactive elements within an aria-hidden=true element are unavailable to users of assistive technologies, like a screen reader.
ARIA input fields have accessible names
Generic names are announced to users of assistive technologies, like a screen reader, when an input field does not have an accessible name specified.
ARIA `meter` elements have accessible names

Screen readers and other assistive technologies rely on labels to properly announce form controls.
`<object>` elements have `[alt]` text
It is advised that alt text is used on '<object>' elements in order to provide meaning to screen reader and other assistive technology users, as these technologies are unable to translate non-text content.

Tables and lists

`<dl>`'s contain only properly-ordered `<dt>` and `<dd>` groups, `<script>`, `<template>` or `<div>` elements.
Screen readers and other assistive technologies may produce poor and inaccurate output when definition lists are not properly marked up.
Definition list items are wrapped in `<dl>` elements
In order for screen readers and other assistive technologies to properly announce definition list items ('<dt>' and '<dd>'), they must be wrapped in parent a '<dl>' element.
