Text too small to read

This mobile usability error occurs when the font size on a mobile website is too small to be easily read on a small screen. This can cause frustration and eye strain for users, leading to a poor user experience.

To avoid this issue, make sure that the font size on websites is large enough to be easily read on a mobile device. Best practices suggest a minimum font size of 16 pixels for body text, and larger sizes for headings and other important text.

Text too small to read

To resolve this issue first visit the page where this issue occurred. After that select the text and do right click, on the right side under style you can see the current font size of the website text. The first step you need to do is change the font size as per your need for an example, I have changed the font size for bullet point 10px to 16 px.

.entry-content li {

  •    line-height: 1.3;

Clickable Elements Too Close Together

This mobile usability error occurs mostly when links, buttons and other clickable elements are too close and make problems for mobile users to navigate easily. Google recommends a minimum size of 48 pixels for all clickable elements.

How to Fix this Issue in Mobile Devices

When faced with this issue, there are several steps you can take to ensure that your clickable elements are spaced out properly. First, you can check the size of an element in Google Chrome by right-clicking on the element and selecting “Inspect”. Then, choose “Styles” in the console on the right side of the page and scroll down to find the element you’re interested in.

Next, copy the object with its attributes and adjust the padding, margin, or border values to increase the tap target size. For example, you can increase the padding-bottom and margin-bottom attributes to 9 pixels and 10 pixels, respectively. Once you’ve made your changes, be sure to test them on a mobile device to ensure that the clickable elements are spaced out properly.

By following these steps, you can fix the “clickable elements too close together” issue and ensure that your mobile website provides a positive user experience. Remember that it’s important to prioritize the user experience on mobile devices, as this is where the majority of web traffic comes from. By making your website mobile-friendly, you can improve engagement, boost search rankings, and ultimately drive more conversions.

Content Wider than Screen

“Content wider than screen” is a common mobile usability error that occurs when the width of the content on a web page is greater than the screen size of the mobile device. This issue can make it difficult for users to navigate your site and can result in a poor user experience.

How to Fix This Issue?

If you are facing “content wider than screen” issue on your wordpress website you can fix this issue by defining the relative values in CSS declarations, instead of absolute values. This can help ensure that your website’s content adjusts to the screen size of the device.

Another common cause of the issue is images with an absolute width that is wider than the screen. To fix this, assign all images a max-width of 100% instead of an absolute value, such as 1000px. This ensures that the images will adjust to the screen size of the device and prevent the content from being wider than the screen.

Example –

img {

  max-width: 100%;

  display: block;


For Table To avoid this error, you should use only relative values for the width of tables in your CSS declarations.

Example –

@media screen and (max-width: 600px) {

th, td {

display: block;

width: 100%;


By using relative values for the width of tables and other elements, you can ensure that your website is mobile-friendly and accessible to all users, regardless of the device they’re using.

Viewport Not Set [to “device-width”]

This error occurs when “viewport meta tag” is not added on the website. viewport meta tag is a HTML tag used to control the size and scaling of a webpage when viewed on mobile devices.

Below is the example of a viewport meta tag – 

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

How to fix this issue?

It is very easy to resolve this issue by adding the above given viewport meta tag in your website you can easily fix this issue. To add this code in your wordpress website you simply need to go to the appearance – theme file editor and under the theme files you can easily find the header.php. Simply paste this code head section.

Uses Incompatible Plugins

Some plugins are using technologies like Flash or Silverlight that are not compatible with many browsers causing problems.
