01:18هنا نشعر بإمكان هذه الأصدام
01:21with additional gaps among the phrases,
01:23yet the browser will fully neglect them.
01:25A second technique that coders frequently employ
01:28to make code easier to comprehend
01:30involves recording it down,
01:32which involves adding remarks to the code
01:34to provide clarity on the actions being performed.
01:37In HTML, we add remarks to code
01:40by keying an open angle bracket,
01:42an exclamation point, then two dashes.
01:45All the content that follows is not acknowledged
01:48or taken into consideration by the web browser.
01:50In order to halt the remark,
01:52we simply conclude it by adding two dashes
01:55and then closing the bracket together.
01:57Numerous text editors are designed to automatically dim,
02:00darken, or blur any identified code segments or notes,
02:04such as the popular code pen editor,
02:06which serves as a significant advantage and assistance.
02:10This way, we are not puzzled when a feature is not functioning.
02:14We can notice that it is just noted out.
02:16We'll now address uppercase versus lowercase letters.
02:20When HTML was just created,
02:22people often capitalized their HTML elements.
02:25Over the years, as HTML matured,
02:28the web community shifted its view,
02:30thinking it is far superior to compose all elements
02:33using lowercase letters.
02:35However, the reality is this does not truly matter.
02:39We uncover an immense number of older websites accessible online,
02:44all written utilizing all capitalized HTML,
02:47while simultaneously discovering billions of current websites
02:50that rigorously avoid utilizing capitalized HTML
02:53throughout their design and construction.
02:56Therefore, the browsers will fully accommodate whichever method that we use.
03:00With that said, most everyone now writes everything in lowercase letters.
03:06It is simply or merely the established practice that is currently followed today.
03:11The use of all caps can, indeed,
03:13have a considerable and significant impact on our eyesight
03:16and can cause strain to our eyes over time.
03:19We may have observed that a few of the elements are quite brief,
03:23looking more like small snippets of information rather than comprehensive entities like
03:28P for a paragraph, B for bold text, or I for italic.
03:34In contrast, others can be much longer,
03:37especially newer ones like article or video.
03:40These longer tags are complete words in English.
03:43For instance, the tag is video, not simply v or vid.
03:48Similarly, we write section, not ssc, footer, not foot, and block quote, not just bq.
03:57So, what could be the reason behind this difference?
04:00And why is there a difference?
04:02So, HTML was primarily conceived and introduced during the late 1980s
04:08and the early 1990s this period of time,
04:11when tech experts were focused on saving every last bit and byte.
04:15Computer machines had just 1 MB of RAM and a mere 20 MB of disk space,
04:20so every letter added to the overall file size.
04:24As HTML evolved, memory capabilities within systems improved significantly.
04:29It became increasingly less crucial to save occasional letters here and there.
04:34And it is notably more crucial to ensure that the code is straightforward and easily understandable.
04:41So, these newer contemporary elements make full usage of words.
04:45This is immensely easier for individuals,
04:48particularly for those who possess remarkable abilities to communicate effectively in the English language.
04:54A final point to address regarding the way HTML is written.
04:58Should we use a closing tag or not?
05:01We've reviewed quite a few amount of time to examine and assess a variety of elements already.
05:06Almost all of them arrive at the destination in pairs, accompanied by an opening and a closing tag.
05:13The modern HTML elements consistently incorporate both an opening and a closing tag.
05:18Like the video element, which we will discuss later on.
05:21At times, we occasionally place no elements between the initial start and the concluding and tagging.
05:29But for a few of the everlasting elements, there is in no way an identifiable sheltered dome or dissonable niche in any respect.
05:37Such as image, which we will explore soon.
05:41These elements were created in the mid-90s.
05:44At that time, the creators thought,
05:46Wouldn't it be simpler and more efficient to leave out the closing tag if it isn't necessary?
05:51And why add one?
05:53Later, the mindset changed and the common practice shifted to placing a slash mark at the end of any element that did not have a matching and closing tag.
06:03The concept is that the element can both open and close all at once.
06:08For a long time, everyone insisted that we must use the slash.
06:12However, towards around the year 2010, people began to take a more laid-back attitude towards this rule.
06:18Frankly, at this time, we are uncertain if a majority of developers actually utilize a closing slash.
06:25By now, the fact that it actually doesn't make a significant difference is widely recognized.
06:31Web browsers are designed to accommodate a wide range of options for organizing and presenting our code.
06:37It is entirely at our discretion and with our team's guidance as to how we would like to proceed in making decisions and executing the plan.
