What are HTML tables

HTML tables are used to organize and display data in a structured, tabular format. They are created using the <table> tag, which acts as a container for the other elements that make up the table, such as rows (<tr>) and cells (<td> or <th>).

Here is an example of a basic table:

Copy code<table>
  <tr>
    <th>Header 1</th>
    <th>Header 2</th>
  </tr>
  <tr>
    <td>Row 1, Cell 1</td>
    <td>Row 1, Cell 2</td>
  </tr>
  <tr>
    <td>Row 2, Cell 1</td>
    <td>Row 2, Cell 2</td>
  </tr>
</table>

In this example, <th> is used for the header cells, and <td> is used for the data cells. The <tr> tag is used to define rows in the table.

You can use CSS to style the table, for example:

Copy codetable {
  border-collapse: collapse;
  width: 100%;
}

th, td {
  border: 1px solid black;
  padding: 8px;
  text-align: left;
}

This will create a border around the table and its cells and set the width of the table to 100% of the available space.

You can use <caption> to provide a title for the table and <thead>, <tbody> and <tfoot> to group rows in a table and make it more accessible.

HTML Block Elements

HTML block elements are HTML elements that define a block-level structure in an HTML document. Examples of block elements include headings (h1, h2, h3, etc.), paragraphs (p), divs (div), lists (ul, ol), and tables (table). These elements take up the full width of their parent container and create a new line before and after the element. They can also be styled with CSS to change the appearance of the element and its contents.

HTML Inline Elements

HTML inline elements are HTML elements that define a span-level structure within an HTML document. Examples of inline elements include text-level semantics such as spans (span), anchors (a), em (emphasized text), and strong (strongly emphasized text). They only take up as much width as necessary, and don’t create a new line before and after the element. They can also be styled with CSS to change the appearance of the element and its contents.

Inline elements are typically used to apply formatting to small portions of text, images, and other inline elements within a block-level element such as a paragraph or div.

What are forms?

Forms are a way for web developers to create a user interface that allows visitors to a website to submit information to the server. They consist of a set of input fields, such as text fields, checkboxes, radio buttons, and drop-down lists, as well as buttons for submitting and resetting the form.

Forms use the HTML <form> element to create the overall structure of the form, and the <input> element to create the individual fields. The <form> element has an action attribute that specifies the URL of the server-side script that will handle the form data, and a method attribute that specifies whether the data should be sent as GET or POST request.

Forms are typically used for tasks such as creating accounts, logging in, submitting feedback, or making purchases. They can also be used to upload files or images.

Forms are often used in combination with JavaScript and CSS to provide client-side validation, dynamic behavior and to make the form more user-friendly.

HTML forms sturcture:

The basic structure of an HTML form typically includes the following elements:

1. <form>: This is the container element for the entire form. It includes the action and method attributes, which specify the URL of the server-side script that will handle the form data, and the method used to send the data (GET or POST).
2. <input>: This element is used to create the individual form fields, such as text fields, checkboxes, radio buttons, and drop-down lists. Each input field has a type attribute that specifies the type of input field (e.g. “text” for a text field, “checkbox” for a checkbox, etc.).
3. <label>: This element is used to provide a text description for each form field, and is typically associated with a specific input field using the “for” attribute.
4. <select>: This element is used to create a drop-down list of options for the user to select from. It contains one or more <option> elements, each of which represents a single option in the list.
5. <textarea>: This element is used to create a multi-line text input field
6. <button>: This element is used to create a submit button for the form. It can also be used to create a reset button that resets all the fields in the form.
7. <fieldset>: This element is used to group related form controls and their labels together.
8. <legend>: This element is used to provide a caption for a fieldset

Note that there are many other elements and attributes that can be used in an HTML form, depending on the specific needs of the form and the application.
