What is the process of ensuring that web pages that are coded with new or advanced techniques are still usable in browsers that do not support the new techniques?

Progressive enhancement

Explanation:

When web applications are built, most times it is necessary to test them on various old and new browsers to ensure that new techniques or features are supported or usable by those browsers. The modality and methodology involved in doing this is called progressive enhancement. With this methodology, web developers focus on building web apps as well as ensure an accessibility balance in the various devices that will access these applications.

Progressive enhancement enforces a rule or logic that allows developers build their web applications from the simplest simplicity to the simplest complexity such that all browsers or other accessing applications render these web applications well.

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
