Yes please. ``` -------------------------------- ### CSS Selector and Declaration Separation Source: https://google.github.io/styleguide/htmlcssguide.html Illustrates the recommended practice of placing each CSS selector and declaration on a new line for improved readability and structure. ```css /* Not recommended */ a:focus, a:active { position: relative; top: 1px; } /* Recommended */ h1, h2, h3 { font-weight: normal; line-height: 1.2; } ``` -------------------------------- ### Use HTTPS for Embedded Resources (HTML/CSS) Source: https://google.github.io/styleguide/htmlcssguide.html This snippet demonstrates the recommended practice of using HTTPS for all embedded resources like scripts, images, and stylesheets. It contrasts this with non-recommended methods that omit the protocol or use HTTP, which can lead to security warnings or broken content. ```html ``` ```css /* Not recommended: omits the protocol */ @import '//fonts.googleapis.com/css?family=Open+Sans'; /* Not recommended: uses HTTP */ @import 'http://fonts.googleapis.com/css?family=Open+Sans'; /* Recommended */ @import 'https://fonts.googleapis.com/css?family=Open+Sans'; ``` -------------------------------- ### CSS Declaration Block Separation Source: https://google.github.io/styleguide/htmlcssguide.html Demonstrates the recommended spacing between a CSS selector and its declaration block, requiring a single space before the opening brace which should be on the same line. ```css /* Not recommended: missing space */ .video{ margin-top: 1em; } /* Not recommended: unnecessary line break */ .video { margin-top: 1em; } /* Recommended */ .video { margin-top: 1em; } ``` -------------------------------- ### Lowercase Usage in HTML and CSS Source: https://google.github.io/styleguide/htmlcssguide.html This code snippet highlights the importance of using only lowercase for HTML element names, attributes, attribute values, CSS selectors, properties, and property values. It shows examples of non-recommended uppercase usage versus the recommended lowercase standard. ```html Home Google ``` ```css /* Not recommended */ color: #E5E5E5; /* Recommended */ color: #e5e5e5; ``` -------------------------------- ### CSS Class Naming Conventions Source: https://google.github.io/styleguide/htmlcssguide.html Demonstrates recommended and not recommended approaches for naming CSS classes. Prefers meaningful, specific, or generic names over presentational or cryptic ones. This improves understandability and reduces the likelihood of unnecessary changes. ```css /* Not recommended: meaningless */ .yee-1901 {} /* Not recommended: presentational */ .button-green {} .clear {} /* Recommended: specific */ .gallery {} .login {} .video {} /* Recommended: generic */ .aux {} .alt {} ``` -------------------------------- ### CSS Selector Prefixes Source: https://google.github.io/styleguide/htmlcssguide.html Shows the optional use of application-specific prefixes for CSS selectors. Prefixes act as namespaces to prevent naming conflicts in large projects or embedded code, making maintenance easier. ```css .adw-help {} /* AdWords */ .maia-note {} /* Maia */ ``` -------------------------------- ### Indentation and Formatting (HTML/CSS) Source: https://google.github.io/styleguide/htmlcssguide.html This section illustrates the recommended indentation style using 2 spaces for both HTML and CSS code.

``` -------------------------------- ### CSS Unit and Leading Zero Handling Source: https://google.github.io/styleguide/htmlcssguide.html Provides guidelines for handling zero values and leading zeros in CSS. Unit specifications can be omitted after zero values unless required for clarity or compatibility. Leading zeros should always be included for values between -1 and 1. ```css flex: 0px; /* This flex-basis component requires a unit. */ flex: 1 1 0px; /* Not ambiguous without the unit, but needed in IE11. */ margin: 0; padding: 0; font-size: 0.8em; ``` -------------------------------- ### HTML General Formatting: New Lines and Indentation Source: https://google.github.io/styleguide/htmlcssguide.html Format HTML by placing each block, list, or table element on a new line and indenting child elements. This improves readability, especially for nested structures. Exceptions for list items (`

`) are allowed if whitespace issues arise, with linters encouraged to warn rather than error. ```html

All recommendations

All recommendations ``` -------------------------------- ### CSS Quotation Mark Usage Source: https://google.github.io/styleguide/htmlcssguide.html Details the preference for single quotes (`''`) over double quotes (`""`) for attribute selectors and property values in CSS, with exceptions for `url()` and `@charset`. ```css /* Not recommended */ @import url("https://www.google.com/css/maia.css"); html { font-family: "open sans", arial, sans-serif; } /* Recommended */ @import url(https://www.google.com/css/maia.css); html { font-family: 'open sans', arial, sans-serif; } ``` -------------------------------- ### CSS !important Declarations Source: https://google.github.io/styleguide/htmlcssguide.html Advises against the use of `!important` declarations in CSS. These declarations disrupt the natural cascade of styles, making them difficult to manage and override. Selector specificity should be used instead to control style application. ```css /* Not recommended */ .example { font-weight: bold !important; } /* Recommended */ .example { font-weight: bold; } ``` -------------------------------- ### CSS Class Name Style and Delimiters Source: https://google.github.io/styleguide/htmlcssguide.html Illustrates best practices for CSS class name length and word separation. Class names should be as short as possible but as long as necessary to convey meaning. Words within class names should be separated by hyphens for improved readability and scannability. ```css /* Not recommended */ .navigation {} .atr {} /* Recommended */ .nav {} .author {} /* Not recommended: does not separate the words “demo” and “image” */ .demoimage {} /* Not recommended: uses underscore instead of hyphen */ .error_status {} /* Recommended */ .video-id {} .ads-sample {} ``` -------------------------------- ### Ensure CSS Validity Source: https://google.github.io/styleguide/htmlcssguide.html Write valid CSS code whenever possible. Utilize tools like the W3C CSS validator to check for errors. Valid CSS ensures that styles are applied correctly, prevents unused code, and maintains a higher baseline quality for stylesheets. ```css /* Example of valid CSS */ body { font-family: Arial, sans-serif; margin: 0; padding: 0; } .container { width: 960px; margin: 0 auto; } ``` -------------------------------- ### Avoid Unnecessary ID Attributes in HTML Source: https://google.github.io/styleguide/htmlcssguide.html Prefer `class` for styling and `data` attributes for scripting over `id`. When `id` is necessary, include a hyphen in its value (e.g., `user-profile`) to prevent conflicts with JavaScript global variables, as `id` attributes are exposed as properties on the `window` object. ```html

...

``` -------------------------------- ### Use Double Quotation Marks for HTML Attributes Source: https://google.github.io/styleguide/htmlcssguide.html Consistently use double quotation marks (`"`) for all HTML attribute values. This standard practice ensures consistency and avoids potential parsing issues that can arise with single quotes (`'`). ```html Sign in Sign in ``` -------------------------------- ### Omit Type Attributes for Scripts and Stylesheets Source: https://google.github.io/styleguide/htmlcssguide.html Avoid using `type` attributes for `` and ` ``` -------------------------------- ### CSS Type and ID Selector Usage Source: https://google.github.io/styleguide/htmlcssguide.html Advises against qualifying class names with type selectors and avoiding ID selectors. This practice improves performance by reducing unnecessary ancestor selectors and avoids the difficulties of ensuring ID uniqueness across a page. Class selectors are preferred. ```css /* Not recommended */ ul.example {} div.error {} /* Recommended */ .example {} .error {} /* Not recommended */ #example {} /* Recommended */ .example {} ``` === COMPLETE CONTENT === This response contains all available snippets from this library.
