The ______ attribute in the audio or video tag specifies if the audio or video should be loaded when the page loads.
- autoplay
- buffers
- loadstart
- preload
The preload attribute in the audio or video tag is used to specify if the media file should be loaded when the page loads. It has values like "none", "metadata", and "auto", allowing developers to optimize loading behavior based on user experience considerations. autoplay, on the other hand, will automatically play the media once it's ready.
What happens if the DOCTYPE declaration is omitted from an HTML document?
- Browsers might display the document in quirks mode.
- External styles will not be applied.
- The document will default to the latest HTML version.
- The document will not be rendered.
If the DOCTYPE declaration is omitted, browsers might default to "quirks mode" instead of "standards mode." Quirks mode can cause inconsistencies in how different browsers display the page because it mimics behavior from older browsers for backward compatibility. Including the appropriate DOCTYPE helps in rendering the page consistently across different browsers.
What considerations should be made to make the HTML body content SEO-friendly?
- Ensuring the use of semantic HTML tags and metadata.
- Keeping paragraphs lengthy and detailed.
- Making sure the body has a colorful design.
- Using as many keywords as possible in the content.
To make HTML content SEO-friendly, one should use semantic HTML tags like
,
The ______ attribute is used to specify the character set used in the HTML document.
- charset
- lang
- meta
- type
The charset attribute is used to specify the character encoding for the HTML document. It's important to set the correct character encoding for a document, especially if it contains characters outside the ASCII range. The correct encoding ensures that all characters in the document are displayed properly. Commonly, UTF-8 is used as a universal character set to cover a broad range of characters from different languages.
Input elements should be enclosed within the ______ element.
- div
- form
- head
- method
Input elements are used to gather user input, and for that data to be useful, it typically needs to be sent to a server. By enclosing input elements within a form element, you define where (action attribute) and how (method attribute) the data will be sent when the form is submitted. The form element acts as a container for these inputs, ensuring they are processed correctly.
What considerations should be taken into account regarding security when using the "get" method for form submission?
- Data will be cached.
- Form data is visible in the URL.
- It's more secure than the "post" method.
- Maximum data length is limited.
The "get" method appends form data to the URL, making it visible to anyone who can see the URL. This can expose sensitive data like passwords or personal information. Additionally, because it's visible in browser history and web server logs, it can increase vulnerability.
The _______ attribute in the blockquote element is used to provide the URL of the quoted source.
- cite
- link
- ref
- source
The cite attribute in the
element provides a reference to the URL of the quoted source. It gives context to the quote by indicating its origin, even though the URL is not directly visible on most browsers unless you view the page's source code. However, it provides semantic meaning and can be useful for future reference or for tools that extract semantic information from web pages.
What happens when a block element is placed inside an inline element, according to HTML5 specifications?
- Both elements are disregarded by the browser.
- The block element is converted to an inline element.
- The outer inline element becomes a block element.
- The page will throw an error.
In the HTML5 specification, it's not considered valid to place a block-level element inside an inline element. If this happens, browsers will often automatically adjust the rendering so that the inline element containing the block is treated as a block-level element. However, this behavior may vary across browsers. It's best practice to avoid such nesting to ensure consistent rendering.
How does the "colspan" attribute affect the structure of a table?
- It adjusts the border color of a cell.
- It allows a cell to span multiple columns.
- It allows a cell to span multiple rows.
- It sets the padding inside a cell.
The "colspan" attribute in HTML is used to allow a table cell to span across multiple columns. It is useful when you want a single cell to extend horizontally over more than one column, such as for headings that should cover several columns beneath them.
In terms of accessibility, how do screen readers interpret lists?
- They announce the list, provide its length, and then read the list items.
- They convert lists into paragraphs.
- They read only the first item in a list.
- They skip over lists without reading them.
Screen readers aim to provide an accessible experience for visually impaired users. When a screen reader encounters a list, it typically announces the presence of the list, indicates how many items are in the list, and then proceeds to read each item. This approach allows users to understand the structure and content of the web page in a comprehensible manner.
