When designing text-based hyperlinks for mobile web pages, it is essential to ensure that the links are easily tappable. Adding padding around the clickable area increases the touch target size, making it easier for users to interact with the link on a mobile device.

Techniques for Mobile-Friendly Links:

Padding the Clickable Area: By adding padding, you increase the touchable area around the link, which helps prevent user frustration due to missed taps.

CSS Example:

a {

padding: 10px;

display: inline-block;

}

Other Options:

B. Keeping links uniform: This refers to making all links look the same, which is good for consistency but doesn't specifically address the issue of touch targets.

C. Deploying graphical links: While graphical links can be effective, they do not necessarily improve touch target size for text-based hyperlinks.

D. Using dynamic page elements near the link: This can lead to a cluttered interface and does not address the touch target issue directly.
