The HTML gadget is part of the Widget block, the general presentation of this block is available in the Widget block guide.
The HTML widget block allows you to embed HTML code from third party services, into your website. In this case, it simply consists in copying (CTRL-C keys) and pasting (CTRL-V keys) a piece of code provided by a third party service.
Enter or paste here the HTML code you want to embed into your website page.
Logically, if the code itself contains an <iframe> tag, the direct embedding option should be enabled, because it is useless to have an iframe within an iframe.
By default, The HTML widget block controls the HTML code and eliminates the erroneous or problematic parts of it. Thus it is recommended to leave the HTML activation enabled, except if the third party service provider performs verifications on the embed code.
If this warning message appears in the HTML widget window, it means that your HTML code refers to resources with an http:// address (non-secure protocol), whereas you configured your website in https:// (secure protocol).
To be secure, a website should only use secure resources. If you use the HTML Widget block to embed third party services into your (secure) website, check that the service provider is compatible with https. Today, it should be systematically the case.
Many web services offer HTML widgets to embed into blogs and websites. It is the case for instance of Accuweather.
The first step consists in configuring the widget of your choice.
