Study Notes

HTML Anchors

The # symbol in an anchor tag's href attribute, without a specific location, creates a link that goes nowhere when clicked.
Assigning id attributes to elements allows anchor tags to link to specific parts of an HTML document using href="#id".
Example: <div id="top"></div> <a href="#top">Go to Top</a> will link to the div with the id "top."

Email Links

mailto: links open the user's email client, pre-filling the "To" field with the specified email address.
Adding ?Subject=Email adds "Email" to the subject line. Example: <a href="mailto:[email protected]?Subject=Email">Email Me</a>

Directory Structure

Organizing files into folders (directories) is crucial coding practice.
A basic web structure might include separate folders for HTML and images.

HTML Forms

HTML forms are created using <form> tags.
Inside the <form> tag are inputs and a submit button. Inputs can be of type text, submit, etc.
The action attribute specifies the destination of form data.
The method attribute can be POST (data sent 'behind the scenes') or GET (data appended to URL as query string). POST is preferred for sensitive data.
GET methods create query strings visible in the URL address bar.

`label` Tag

The label tag adds descriptive text for inputs, and clicking the label focuses the associated input.
Use the for attribute in the label to link it to the input's id, e.g., <label for="myInput">My Input:</label> <input id="myInput" type="text">

HTML5 Elements: Article and Aside

The <article> element defines an independent, self-contained piece of content within a document.
The <aside> element contains content tangentially related to the main content.

HTML5 Meter Element

The <meter> element displays a visual gauge representing a value within a specified range.
Attributes include min, max, and value. Text between the opening and closing tags serves as fallback content for older browsers.
Example: <meter min="0" max="100" value="50">50%</meter>

HTML5 Video

The <video> element embeds video content.
Attributes include height, width, and controls.
The <source> element specifies video file sources with src (URL) and type (mime-type). Multiple <source> elements can provide different formats for browser compatibility. Example: <video width="640" height="480" controls><source src="myvideo.mp4" type="video/mp4"><source src="myvideo.ogg" type="video/ogg">Your browser does not support the video tag.</video>

HTML5 Audio

The <audio> element embeds audio content.
It uses controls attribute and <source> element (similar to video) to specify audio files.

Linking External CSS

External CSS files are linked using the <link> tag within the <head> section of an HTML document.
Attributes for <link> include rel="stylesheet", type="text/css", and href="[path/to/file.css]".

Efficient CSS Selectors

Using commas to separate selectors in CSS applies the same styles to multiple elements efficiently, minimizing code repetition. Example: h1, h2 { color: blue; }

HTML Element State Styling with CSS

CSS can style HTML elements based on their state (e.g., :hover, :active).

CSS Fonts

Multiple font families can be specified, separated by commas (font-family: Helvetica Neue, Helvetica, sans-serif;). The browser uses the first available font.

CSS Opacity

The opacity property controls the transparency of an element (0.0 fully transparent, 1.0 fully opaque).

CSS Alpha Color Space

rgba() values specify color with an alpha channel (fourth value) controlling opacity (0.0 to 1.0). Example: background-color: rgba(255, 0, 0, 0.5); (half-transparent red)
