HTML Code Example

HTML tag

The HTML element is used as a container for metadata (data about data). It is used between tag and tag. The head of an HTML document is a part whose content is not displayed in the browser on page loading. It just contains metadata about the HTML document which specifies data about the HTML document.
An HTML head can contain lots of metadata information. But head part has a crucial role an HTML document while creating a website.

Columns in bootstrap

In bootstrap, every row is divided into 12 equal parts. Its provide mobile friendly and all device responsive design framework to manage html them on all devices.

Responsive containers

Responsive containers allow you to specify a class that is 100% wide until the specified breakpoint is reached, after which we apply max-widths for each of the higher breakpoints. For example, .container-sm is 100% wide to start until the sm breakpoint is reached, where it will scale up with md, lg, xl, and xxl.

Fluid containers

In bootstrap use .container-fluid class for a full width container, spanning the entire width of the viewport.

Utilities for layout

For faster mobile-friendly and responsive development, Bootstrap includes dozens of utility classes for showing, hiding, aligning, and spacing content.
Bootstrap is built with flexbox, but not every element’s display has been changed to display: flex as this would add many unnecessary overrides and unexpectedly change key browser behaviors. Most of our components are built with flexbox enabled.
Use the margin and padding spacing utilities to control how elements and components are spaced and sized. Bootstrap includes a six-level scale for spacing utilities, based on a 1rem value default $spacer variable. Choose values for all viewports (e.g., .me-3 for margin-right: 1rem in LTR), or pick responsive variants to target specific viewports (e.g., .me-md-3 for margin-right: 1rem —in LTR— starting at the md breakpoint).
