The page's dimensions exceed the size of the device screen

I created this basic HTML content using React

<!doctype html>
<html><head><title data-react-helmet="true"></title><style type="text/css" data-styled-components="" data-styled-components-is-local="true"></style></head><body><div id="app"><div data-reactroot="">Hello</div></div></body></html>

Upon viewing it in Chrome's mobile display, the dimensions of the page are larger than the screen size. For instance, on an iPhone 5 with a dimension of 320x568, my page width is set at 980px. Surprisingly, no CSS has been applied.

This discrepancy requires me to increase the font size to maintain readability on the mobile display but results in overly large text on desktop view. How can the size of the page exceed that of the screen? What could be causing this issue?

Answer №1

If you're searching for a way to customize your website for different screen sizes, the @media selector is what you need. You can find more information about it here.

To implement this, simply add the following code snippet at the bottom of your existing code:

@media only screen and (max-width: ##px) {

}

Replace "##" with the max-width of the phone screens you want to target.

Within the brackets, you have the flexibility to adjust various aspects of your website specifically for phones. For example, you can change the font size like so:

If your original CSS included:

.desktop {
font-size: 30px;
}

You can create a phone-specific style by adding:

@media only screen and (max-width: 568px) {
.desktop {
font-size: 15px;
}
}

I hope this explanation proves helpful! If it does, feel free to upvote and mark as acceptable.

Discovered the answer on this page, by inserting a meta tag for viewport

<meta name="viewport" content="width=device-width, initial-scale=1.0">

Answer №3

Some sections of the site need to be revamped, like consolidating everything into a single vertical layout for better compatibility with mobile devices. In the React Native EditScreenInfo module, I introduced a query parameter: mob=yes. While the actual value doesn't matter, the backend code utilizes it to identify mobile users. Therefore, the server determines which design template to apply based on this parameter. Additionally, I utilized JavaScript to optimize text size within different HTML tags for mobile viewing.
