Different HTML Tags and Elements Explained

HTML tags are the building blocks of a website's structure, and they're used to define different elements on a web page. A basic HTML document consists of a doctype declaration, an html tag, and a head and body section.

The head section contains metadata about the document, such as the title, charset, and links to external stylesheets or scripts. The body section contains the content of the webpage, including text, images, and other media.

The title tag is a crucial element in the head section, as it sets the title of the webpage that appears in search engine results and browser tabs. A well-crafted title tag can improve a website's visibility and click-through rate.

The div tag is a generic container element that can be used to group other elements together, but it doesn't have any inherent meaning or styling.

HTML is a fundamental building block of the web, and understanding its basics is essential for any web developer or enthusiast.

HTML entities are used to replace reserved characters that are reserved by HTML, making it possible to display special characters on web pages.

In order to create web pages, you need to know how to use HTML tags to structure your content.

HTML entities allow you to display special characters, such as © for copyright symbols, on web pages.

This is crucial for adding personality and visual appeal to your web content.

HTML entities replace the actual character with a code that the browser can interpret, making it possible to display those characters on the web.

HTML Elements are the building blocks of web pages, and they come in two main types: non-replaced and replaced.

Non-replaced elements, like paragraphs, headers, and lists, are surrounded by opening and (sometimes optional) closing tags that can turn text into a hyperlink, make a sentence into a header, or give emphasis to words.

The Img tag is used to show images on a web page. It's a powerful tool that allows you to display images from anywhere online or from a file on your web page.

The most important attribute for the Img tag is src, which tells the browser where the picture is located. You can set the src attribute to a URL of an image online, like the freeCodeCamp Logo located at https://avatars0.githubusercontent.com/u/9892522?v=4&s=400.

To display a locally hosted image, you can use the src attribute with the path to the image file. For example, if you have a folder called images with the freeCodeCamp.jpeg inside, you can set the src attribute to "images/freeCodeCamp.jpeg" as long as the 'images' folder is in the same location as the index.html file.

The Img tag won't display an image without the src attribute, so make sure to include it when using the tag.

Non-Replaced Elements are the ones that are not replaced by objects like images or UI widgets. They can be styled and contain text and other tags as sub-elements.

The paragraph, header, and lists are all non-replaced elements. They have opening and (sometimes optional) closing tags that surround them.

Non-replaced elements can turn a phrase or image into a hyperlink, make a sentence into a header, or give emphasis to words.

For example, the paragraph element can be used to make a sentence into a header, as shown in the following example: This is a header :D.

Suggestion: Html Line Spacing after Paragraph

A character entity looks similar to this: &. To use them, you need to insert the correct code into your HTML document.

You can find these codes in a character entity reference chart. It's like a map that helps you navigate the different symbols and characters you can use.

For example, if you want to use a copyright symbol, you'll need to insert © into your code. This will display the symbol in your web page.

Just remember to replace the ampersand (&) with the correct code for the symbol you want to use. It's like a secret language that only works in HTML.

The Div Align attribute is a powerful tool for controlling the layout of your HTML elements. It allows you to horizontally align the contents within a div.

You can use the Div Align attribute to center text within a div, as seen in the "Div Align Attribute Example". The text will be perfectly centered, making it easy to create visually appealing layouts.

In this example, the Div Align attribute is used to align the text horizontally, creating a clean and professional look. This is especially useful when working with divs that contain text or other elements that need to be aligned.

In HTML, attributes and entities play a crucial role in defining the structure and content of web pages.

Attributes are used to provide additional information about HTML elements, such as the src attribute in the img element, which specifies the URL of the image to be displayed.

Entities are used to represent special characters in HTML, like   for a non-breaking space.

For example, the © entity is used to display a copyright symbol, and the < entity is used to display a less-than sign.

For another approach, see: Html Character Entities

The number attribute is used to define a numeric input field in HTML. It's a convenient way to get a number from the user.

You can set restrictions on what numbers are accepted using the number attribute. This is especially useful when you need to limit the input to a specific range.

For example, you can use the number attribute to create a numeric input field that only accepts values from 1 to 5. This is a common use case when you need to collect ratings or scores.

The number attribute is often used in conjunction with other attributes to create more complex input fields.

Customizable data attributes are now possible in HTML5 with the introduction of the data-* attribute, which allows developers to store extra information about different elements.

This attribute is a game-changer for web development, enabling developers to add custom attributes without risking page rendering issues or invalid documents.

Adding custom attributes in older versions of HTML was a risk, but HTML5 has made it safe and efficient.

Entities are used to replace reserved characters in HTML, like the less than and greater than signs, which can be mistaken for tags.

In HTML, some characters are reserved and can cause confusion if used directly. For instance, the less than and greater than signs can be mixed up with tags.

Reserved characters in HTML need to be replaced with entities to avoid any confusion or errors in the code. This ensures that the browser renders the content correctly.

If you use the less than or greater than signs in your text, the browser might mix them up with tags, which can lead to unexpected results.

Forms and Inputs are a crucial part of HTML, allowing users to interact with your website by submitting data.

A form can contain various control elements, including input fields, textareas, select menus, and buttons.

These control elements can have different types, such as text, email, password, checkbox, radio, submit, range, search, date, time, week, color, and datalist.

Some of these types, like password, mask the characters entered by the user, while others, like submit, trigger a form submission.

Here are some common input types you can use in a form:

A hidden input field, on the other hand, is not visible to the user but can store data that needs to be updated when the form is submitted.

The submit button is a crucial element in forms. It's used to submit form data to a form-handler.

A form-handler is typically a server page with a script for processing input data. This is where the form data gets processed and handled.

The form-handler is specified in the form's action attribute. This attribute is where you tell the browser where to send the form data.

If you omit the submit button's value attribute, the button will get a default text. This is a good thing to know when designing your forms.

The submit button type is defined by the input type attribute, which in this case is set to "submit". This tells the browser that this button is meant for submitting form data.

Email input fields are a great way to collect email addresses from users. They can be automatically validated in some browsers, making it easier to ensure users enter a valid email address.

Some smartphones recognize the email type and add ".com" to the keyboard to match email input. This can help users quickly enter a valid email address.

The range input type is a control for entering a number whose exact value is not important, like a slider control.

A different take: Html Cache Control

By default, the range is set from 0 to 100, but you can adjust this range with the min and max attributes. For example, you can set the minimum value to 10 and the maximum value to 500.

You can also specify the step value, which determines the increments between values. This means you can control how fine or coarse the slider's resolution is.

For instance, if you set the step value to 10, the user can only select values that are multiples of 10. This can be useful when you need to restrict the user's input to specific values.

The "controls" attribute is a simple yet useful feature that determines whether controls like play/pause buttons or volume sliders appear.

You can set it to true by adding it into the tag, and if it's not present, it defaults to false.

This attribute is a great way to customize the look and feel of your forms and inputs, and it's easy to implement.

The "controls" attribute can be set to either true or false, giving you flexibility in designing your user interface.

You can store data on the client using two objects: window.localStorage and window.sessionStorage. The former stores data with no expiration date and lives until removed, while the latter stores data for one session and loses data when the browser or browser tab is closed.

To store complex data structures, you'll need to serialize and de-serialize them using JSON.stringify() and JSON.parse(). For example, you can convert a JSON object to a string and save it in local storage.

You can retrieve the JSON object from the string stored in local storage using JSON.parse().

Web Storage is a game-changer for developers. It allows them to store data locally on the client's computer, giving users a faster and more seamless experience.

The main advantage of Web Storage is that it replaces cookies, which are limited to 4 KB of data. Local storage, on the other hand, can store at least 5 MB of data.

Expand your knowledge: Html Web Storage

Web Storage comes in two types: window.localStorage and window.sessionStorage. The former stores data permanently until it's removed, while the latter stores data for one session and loses it when the browser or tab is closed.

To store complex data structures, you need to serialize and de-serialize them using JSON.stringify() and JSON.parse(). This will convert your JSON object to a string and back to an object.

Local storage is a powerful tool that can store data permanently on the client's computer, unless the user erases it. This means you don't have to worry about data expiring or being lost when the browser is closed.
