Study Notes

HTML Structure Part II

• HTML semantics are elements that clearly describe their meaning to both the browser and the developer.
• Non-semantic elements like <div> and <span> offer no information about content, while semantic elements like <form>, <table>, and <article> define content.
• Semantic elements are categorized into four groups: document structure, textual meaning, media type, and correlation tags.

Semantic Element Categories

• Document Structure Tags: <header>, <footer>, <main>, <nav>, <section>, <aside>, <article>.
• Textual Meaning Tags: <h1> to <h6>, <strong>, <mark>, <cite>, <blockquote>, <time>.
• Media Type Tags: <audio>, <video>, <picture>.
• Correlation Tags: <ul>, <ol>, <figure>, <address>.

HTML4 vs HTML5

• HTML4 frequently used numerous classes and IDs for structuring content, while HTML5 employs semantic tags (e.g., <header>, <nav>, <footer>).
• HTML5's semantic tags offer a structured approach to blog posts.
• The use of <main> in HTML5 denotes the core content of a webpage, distinguishing it from other sections.
• HTML5 introduced features allowing a single <header> and <footer> for a webpage, and multiple for sections.
• <main> tags should not be nested inside other elements like <header>, <footer>, or <nav>.
• <header/footer> tags may appear multiple times within a page element for sub-sections. However, one is usually sufficient for the entire page and should be placed within the body element.

<header> & <footer>

• The <header> element typically includes introductory content or navigational aids (logo, search form, author name).
• The <footer> element contains information like the author, copyright, or links to related resources.
• <header> and <footer> tags can be used multiple times within a page, but only once within a single page's <body>.

<nav>

• The <nav> element delineates navigational elements, like menus, tables of contents, or links to external documents, with emphasis on website or page navigation.
• Not all links need to be inside a <nav>.
• <nav> tags are usually located in the <header> of a page.

<main>

• The <main> element signifies the central content of a document, distinct from supplementary material like headers, footers, sidebars, search functions or navigation.
• This element should not repeat content present in other pages or documents.
• It typically follows the <header> element. The <main> element is the content container of the webpage. It does not contain any elements intended to act as navigation, headers, footers, aside or similar elements.

<section> vs <article>

• The <section> encompasses general sections within a document, usually including headers and likely footers.
• The <article> signifies a stand-alone piece of content that could exist independently (blog posts, newspaper articles, or any independent content that stands on its own). Content inside <article> should be reusable or shareable as a single unit.

<aside>

• The <aside> element represents content supplementary to the main flow.
• It often appears as sidebars or call-out boxes. Information included within <aside> is indirectly related to the main content.

HTML Semantic Examples

• There are several real-world examples of HTML semantics in action, such as Twitter or Dev.to. Content tags clearly indicate the purpose of the webpage content.
• Webpage elements should use tags that describe the type of content being conveyed.
• Real-world examples of HTML semantically structured sites include, but are not limited to, those from major tech companies and social media sites.

HTML Attributes

• id attribute
• Defines unique identifiers for elements.
• Used with CSS and JavaScript for applying specific styles and operations.
• Unique to each element.
• class attribute
• Assigns class names to elements.
• Used for applying similar styles/actions across multiple elements.
• Can be assigned to multiple elements.

HTML Forms

• Forms facilitate user interaction and data gathering.
• They collect data, which frequently goes server-side.
• Controls encompass input fields, dropdown lists, buttons, and other components.
• Validation logic can automatically enforce format restrictions to ensure data integrity.
• The form element <form> encapsulates the form's elements, attributes, and data processing logic.
• The action attribute indicates where the server should send data.
• The method attribute dictates the data transmission method used (usually GET or POST).

<form>

• The <form> element acts as a container for various input components.
• The action attribute indicates where entered data will be sent when the form is submitted.
• The method attribute dictates the method to submit data (usually GET or POST).

Form Common Elements Required

• <fieldset> elements group related input elements.
• <legend> elements define the caption for <fieldset> groupings.
• <label> elements associate text with their related input field.
• <input> attributes accept different input types (like text fields, checkboxes, radio buttons):
  • type="text", type="email", type="password", type="number", type="date", type="datetime-local" and other types for specific input.
  • Attributes like required, placeholder, pattern, maxlength, minlength, min, max, step and list attribute provide means to limit/control input.
• <select> elements present options for selection.
• <option> elements define selectable options within <select>.
• <datalist> elements offer a list of values to choose from (used with <input>).
• <button>, type ="submit", Reset/button elements act as clickable buttons. Buttons can be used for submit functionality, and reset functionality.
• Input Types:
  • type="text", type="email", type="password", type="number", type="date", type="datetime-local" and other types for specific input.
  • Attributes like required, placeholder, pattern, maxlength, minlength, min, max, step and list attribute provide means to limit/control input.
• checkbox, radio elements for multiple/single selections
• Other possible types for forms, <textarea>

HTML Rule of Thumb

• Before coding, prepare a quick mockup to define data types required for the form.
• Design a simple form that prioritizes user understanding and avoids unnecessary complexity.
• Request only the information needed; do not ask for extraneous data. Forms should be concise and easy to use.
