What is preventing me from using CSS to customize elements within InfoWindows?

I've been attempting to adjust the font-size of elements within my InfoWindows, but I'm facing some challenges. Here's a snippet of the code for my InfoWindow:

<InfoWindow 
          marker={this.state.activeMarker}
          visible={this.state.showingInfoWindow}
          onClose={this.onClose}
        >
          <div>
            <h1>{this.state.selectedPlace.name}</h1>
            <h4>{this.state.selectedPlace.busy}</h4>
          </div>
</InfoWindow>

When I attempt to use CSS to style elements like h1 and h4 inside the info windows, nothing seems to change. Is there a known fix for this? While I understand that editing actual InfoWindows is challenging, should it be difficult to modify their child elements?

Answer №1

When it comes to infoWindow customization, you have the ability to override the styles of .gm-style .gm-style-iw as mentioned here.

To modify the appearance of your infowindow, you can include something like this in your CSS file:

.gm-style .gm-style-iw {
    font-size: 20px;
}

In addition to using CSS, you can also apply different styling elements when calling your InfoWindow in ReactJS code:

<InfoWindow>
                 <div>
                 <h1 id="firstHeading" class="firstHeading">Custom Heading</h1>
                 <span>This is a customized InfoWindow message.</span>
              </div>
             </InfoWindow>

Take a look at this sample code where I utilize the react-google-maps library. Remember to adjust the API key value in the index.js file for the code to work properly.

Additionally, check out this example code where I changed the infowindow style using CSS within plain JavaScript.
