There are moments when you’re faced with a challenge, a task that you haven’t encountered before. It can be daunting, but it’s also an opportunity to showcase your abilities and demonstrate your worth.
I remember one instance when a major bug surfaced and my team was at a loss as to its cause. We anticipated a lengthy and difficult resolution process. But to our surprise, the solution was relatively simple. I took ownership of the problem and was able to fix the issue, much to the satisfaction of my manager and team.”
It’s not always easy to be put in a position of uncertainty, but it can also be a chance to prove oneself and take the lead.
Description
The text size of input fields on a website can affect the user experience, particularly on Safari on the iPhone. If the font size is set to less than 16 pixels, the browser will automatically zoom in on the form field when it is tapped on. While this behavior is intentional, it can disrupt the intended user experience. Therefore, it may be beneficial to disable this feature and maintain a static zoom when filling out form controls.
Solution
If you’re running into an issue on iOS devices where the screen zooms in when you tap on an input form field, there are a few things you can try to resolve the issue. Here are a couple of solutions:
Update your viewport meta tag: In the head of your HTML document, make sure you have a viewport meta tag that includes the “user-scalable=no” attribute. This will prevent the user from zooming in on the page.
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">
It’s important to keep in mind that while the <meta> tag is used to provide metadata about a page, it does not affect the appearance of the page itself.
It’s also important to note that the <meta> tag should be placed within the <head> section of an HTML document, and should not have any content of its own, instead, it uses its attributes to store metadata information.
viewport tag indicates the size of the viewport on the device, allows to make sure that the page will be responsive and look good on all the devices.
Add a CSS property: You can also add a CSS property called “user-select: none” to the input fields to disable the zoom feature.
input { -webkit-user-select: none; }
Using CSS, simply set your BODY font size to 16px, and then use CSS again to set the INPUT and SELECT field font size to 1em OR 100%. For example;
body { font-size: 16px; }
input, select { font-size: 100%; }
But the above font-size changes might not meet your user experience design so it is advisable to change the font-size iff one is satisfied with the UI.
Please note that while disabling the zoom functionnality can improve the user experience, some users might need the zoom functionnality for accessibility reasons, so you may want to consider providing the users an option to enable it again or to keep it accessible for accessibility guidelines.
