Tables

Element Name	Use
`<table>`	Used for displaying tabular data.
`<td>`	Defines a cell in the table (table data).
`<tr>`	Defines a row of cells in the table.
`<th>`	Defines a header cell.
`<thead>`, `<tbody>`, `<tfoot>`	Used to organize the table semantically. Helps with structure but not necessary for rendering.
`colspan` / `rowspan`	Attributes that allow a cell to span multiple columns or rows.

The <form> element is used to collect user input.

<input>: Most common form element with multiple types (text, password, email, etc.). Use placeholder for hints.
<label>: Associated with an input using the for attribute (must match input’s id).
<button>: Default behavior is submitting the form. You can change it using the type attribute.
Checkbox: Use checked to make it selected by default.
Radio buttons: Only one can be selected within a group (same name value). The value is sent when submitted.
<select> & <option>: Used for dropdowns. Use selected for the default choice.
Range: Use min, max, and step for range inputs.
<textarea>: Multi-line text input. Use rows and cols attributes to control size.

The name attribute is used to reference each input’s value when the form is submitted.

You can add client-side validation using attributes like required, minlength, maxlength, etc.

Some input types (like email or url) come with built-in validation.
