As you start building your website, you might come across some outdated HTML tags that are no longer supported. The good news is that most modern browsers will still render them, but it's essential to know which ones to avoid to ensure your site remains compatible with future browsers and devices.
The b and i tags, for example, were used to format text as bold and italic, but they've been replaced by more semantic alternatives like strong and em. You can still use them for now, but it's recommended to switch to the newer tags for better accessibility and search engine optimization.
Using deprecated tags can lead to issues with accessibility and search engine optimization. The font tag, for instance, was used to change the font face, size, and color, but it's now considered outdated and should be replaced with CSS styles.
If you're unsure which tags to use, start by checking the HTML5 specification and looking for tags with a "deprecated" note.

Deprecated HTML Tags
Deprecated HTML tags are those that have been replaced by newer, better alternatives. The applet tag, for example, has been deprecated in favor of the object tag.
Some deprecated tags are still widely used, but they may not be supported in modern browsers or future versions of HTML. The basefont tag, which sets the default text-color and font-size, has been replaced by font style sheets.
The center tag, used to center text, has been deprecated in favor of the text-align property. This change makes it easier to center text without using a deprecated tag.
The dir tag, which creates a directory list, has been replaced by the ul tag. This change makes it easier to create lists without using a deprecated tag.
Here is a list of some deprecated tags and their alternatives:
The font tag, which changes the color, size, and style of text, has been replaced by font-family, font-size, and color. The isindex tag, which creates a single-line input field, has been replaced by the form tag.
The menu tag, which creates a menu list, has been replaced by the ul tag. The plaintext tag, which renders all text in the document, has been replaced by the pre tag.
The s tag, which strikes through text, has been replaced by the text-decoration property. The strike tag, which also strikes through text, has been replaced by the text-decoration property.
The u tag, which underlines text, has been replaced by the text-decoration property. The xmp tag, which renders preformatted text, has been replaced by the pre tag.
These changes make it easier to create modern, responsive web pages without using deprecated tags.

HTML5 Changes
HTML5 has introduced several changes that have impacted the way we use deprecated HTML tags. One of the most significant changes is the introduction of semantic meaning to certain tags, such as nav, header, and footer, which have replaced the old div tags for these purposes.
The canvas tag has been added to HTML5, allowing for dynamic graphics and animations to be created on the fly. This has made it easier to create interactive web pages without the need for external plugins.
A unique perspective: Difference of Html and Html5
The video and audio tags have also been updated to provide a more streamlined way of embedding multimedia content into web pages. This has reduced the need for third-party plugins and made it easier to create multimedia-rich web experiences.
The introduction of the canvas tag has also led to the removal of the object tag, which was previously used for embedding multimedia content. This change has streamlined the way we embed multimedia content into web pages.
