The short answer is "Yes." By utilizing suitable punctuation, such as commas or period letters, screen readers may explain the image in a more "human" manner. This can be helpful for those who need to read out loud or who are blind.
Periods and commas are used in alt text to break up long sentences and provide extra information about the image. For example, if the image is a photograph of a painting and you want people viewing it to know this fact, you could include "by Raphael" as an alternative description of the image. This is useful because not everyone knows what role artists play in creating paintings! The same principle applies to images with multiple elements; for example, if there's a person in the picture and a book lying on the ground, someone viewing the image would benefit from knowing that these are the only two items contained within it.
It's also important to remember that not everyone who views your website will be using a browser that supports HTML5 or CSS3. If you omit appropriate tags, many browsers will choose to display all characters as dots "..." instead. This is called "text substitution" and it's something you should avoid unless you have a very good reason for doing so.
Texting does not need punctuation at the conclusion of a sentence. It's perfectly OK to just let it dangle. Using a period gives a sentence a sense of completion. Things come to an end because of periods. Without them, conversations would never stop.
Text messaging has no spell checker, so mistakes will be sent in all caps and with exclamation marks! Use proper spelling and grammar when sending texts. If you're not sure about something, ask questions - don't assume you know what someone means. Also, avoid text slang or abbreviations. They may be common in your head, but not everyone else's will understand them.
Periods are very important in writing letters too. You should always begin letters with the person's full name, followed by the address. Then comes the subject line- this is what will help people find your letter. Make sure that you put your letter's sender on the return address for it to reach its destination.
At the end of a letter, you should sign your name. This shows that you are who you say you are and that you are responsible for your words. Letters are usually written by someone who is not face to face with the addressee, so they need a way to identify themselves. The use of signatures was very common in letters sent through the mail until recently. Today, email addresses are used instead.
The usage of a period has taken on a similar connotation in the context of texting. So, to guarantee that your words are received and comprehended with the seriousness you intend, leave the period out of the final phrase. You may even use an exclamation mark to emphasize your seriousness. These punctuation marks are called "showing signs" or "indicating phrases."
Another reason for using periods in writing is that they create distance between sentences, which gives the reader time to absorb the information before being asked to read another sentence. The use of periods in this way is called "periodization." A third reason for including periods in written language is that they indicate the end of a thought.
In conclusion, periods are useful tools for writing clear messages. They can be used to show respect, to ask questions, to express surprise, and so forth.
Reading in between the lines Though periods can still be used to indicate the conclusion of a sentence in a text message, many users will leave them out (especially if the message is only one sentence long). This inclination now effects how we view them slightly. While periods were once used exclusively to mark the end of sentences, they are now also used as subtle cues in conversations.
Image Caption vs. Alt Text: An image caption is text that shows on the screen. Alternate text is read aloud to assistive technology users but is concealed from sighted users. Image captions are useful for describing images in articles or websites.
There are two types of alternate text: descriptive and textual. Descriptive alternative text provides a brief description of the image that is read by screen readers when no other text is available. For example, if there was no text below an image of a car, a screen reader would read "image" followed by the word "car". This type of alternate text is useful when you do not want to provide a long explanation about the image in a blog post or article.
Textual alternative text includes regular text that can be displayed as part of your website's design. It can also include additional information about the image being used, such as where it came from or what it looks like in real life. This type of alternate text requires human judgment because it is up to the author of the web page to decide what should go in it. They can use their discretion to exclude any text they feel isn't relevant or helpful for their audience.
Alternative text helps people who access the web using text-only browsers (such as JAWS or VoiceOver) understand what the image contains.
