How do the CSS properties table-layout and width interact when styling a table?
- They work independently of each other.
- table-layout determines how widths are calculated.
- table-layout overrides width.
- width only applies if table-layout is set to fixed.
The table-layout property determines the algorithm used to lay out table cells, rows, and columns. When it's set to auto (the default), the browser calculates the width of the table and its cells to fit the content. When set to fixed, column widths are set by the width of the first row of cells, the table's width, and any specified column widths. Using fixed can allow for faster rendering in large tables.
How does the preload attribute in the audio or video tags affect the loading of multimedia content?
- It forces the media to play repeatedly.
- It sets the initial volume of the media.
- It sets the starting time of the media playback.
- It specifies if/how the media should be loaded when the page loads.
The preload attribute in the audio or video tags provides hints to the browser about how the media file should be preloaded. There are three values it can take: "none" (means the media should not be preloaded), "metadata" (only metadata should be loaded), and "auto" (the media should be loaded entirely or up to a browser-defined limit). This helps optimize the user experience by potentially reducing load times or unnecessary data usage.
