This first block of code uses semantic elements:. First, it is much easier to read. This is probably the first thing you will notice when looking at the first block of code using semantic elements. This is a small example, but as a programmer you can be reading through hundreds or thousands of lines of code. The easier it is to read and understand that code, the easier it makes your job.
It has greater accessibility. You are not the only one that finds semantic elements easier to understand. Search engines and assistive technologies like screen readers for users with a sight impairment are also able to better understand the context and content of your website, meaning a better experience for your users.
Overall, semantic elements also lead to more consistent code. There are so many ways that you can create a header element, and they all depend on the personal preference of the programmer.
By creating a standard semantic element, it makes it easier for everyone. Both these elements are used for sectioning a content, and yes, they can definitely be used interchangeably. To decide which of these you should choose, take note of the following:. However, this is not intended to make the text smaller. It is just describing its content, not prescribing presentation.
While humans can read time that can disambiguate through context in the normal way, the computers can read the ISO date and see the date, time, and the time zone. With the introduction of HTML5, you can now place it directly into the page itself. However, not all support the same video file format. My recommendation for a wide range of compatibilty is MP4, as it is the most widely accepted format.
The element enables you to indicate alternative video files which the browser may choose from. There are even more if you click the link at the bottom. You set it to true by adding it into the tag, if it is not present in the tag it is set to false. If set to true, the video will begin playing as soon as enough of the video has buffered for it to be able to play.
Many people find autoplaying videos as disruptive or annoying so use this feature sparingly. Also note, that some mobile browsers, such as Safari for iOS, ignore this attribute. I am not sure about class 10 students.
