Show Details

Properly size images
Images can slow down the page's load time. Iranzehn.com should consider serving more appropriate-sized images.

Defer offscreen images
Time to Interactive can be slowed down by resources on the page. Iranzehn.com should consider lazy-loading offscreen and hidden images.

Minify CSS
Cascading Style Sheets (CSS) files can contribute to network payload sizes. Iranzehn.com should consider minifying CSS files.

Minify JavaScript
JavaScript (JS) files can contribute to network payload sizes and increase script parse times. Iranzehn.com should consider minifying JS files.

Remove unused CSS

Show Details

Preload key requests
Key requests can be preloaded by using '<link rel=preload>'. Iranzehn.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
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 iranzehn.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.

`[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.

`[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-*]` 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.

Image elements have `[alt]` attributes
Provide short and descriptive alternative text where possible on informative elements.

`<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.

Links have a discernible name
In order to improve the navigation for screen reader and other assistive technology users, use link text that is unique, focusable and discernible.

`<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.

Presentational `<table>` elements avoid using `<th>`, `<caption>` or the `[summary]` attribute.
It is advised to not include data elements in tables which are used for layout purposes, as it may create confusion for screen reader and other assistive technology users.

Lists contain only `<li>` elements and script supporting elements (`<script>` and `<template>`).
Use proper list structure to aid screen readers and other assistive technologies.

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 `[lang]` attribute
It is advised to provide a lang attribute so that screen readers and other assistive technologies are guaranteed to announce the page's text correctly. When not provided, the user's default language setting will be used which may cause inaccuracies.

`<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.

Audio and video

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

`<video>` elements contain a `<track>` element with `[kind="description"]`
Iranzehn.com may provide relevant information that dialogue cannot, by using audio descriptions.

Performance

Indicates how well the page is performing and highlights opportunities where performance may be improved for iranzehn.com. This includes details about optimizing page load times which can result in a better user experience.

Metrics

Speed Index — 3.0 s
The time taken for the page contents to be visibly populated.

Opportunities

Properly size images
Images can slow down the page's load time. Iranzehn.com should consider serving more appropriate-sized images.

Defer offscreen images
Time to Interactive can be slowed down by resources on the page. Iranzehn.com should consider lazy-loading offscreen and hidden images.

Minify CSS
Cascading Style Sheets (CSS) files can contribute to network payload sizes. Iranzehn.com should consider minifying CSS files.

Minify JavaScript
JavaScript (JS) files can contribute to network payload sizes and increase script parse times. Iranzehn.com should consider minifying JS files.

Remove unused CSS
Dead and/or unused rules in Style Sheets (CSS) can contribute to network payload sizes. Iranzehn.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
Image formats like PNG and JPEG have poor compression when compared to other next-gen formats, such as JPEG 200, JPEG XR and WebP.

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.

Initial server response time was short — Root document took 140 ms
It is advised to keep the server response time short for the main document, because all other requests depend on it.

Preload key requests
Key requests can be preloaded by using '<link rel=preload>'. Iranzehn.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
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.
