Tutorial on how to modify element.style inline styles

Preface

When we were writing the web page style above, we found that sometimes, no matter how we modified the value in the style, the style on the page would not be modified. When you use the tool to view it, you will find that there will be a value of element.style in it, but you cannot find where this value appears and cannot modify it.

In fact, element.style is an inline style, which is often hard-coded in some JavaScript code. This method is quite bad. But sometimes, we encounter when using third-party js files. So how do we modify it? Use the !important syntax priority in the source code to achieve the effect we want.

For example:

By default, the transparent image above is green. We can't find how to modify element.style. At this time, we can modify it in the following CSS style sheet:

As shown above, add an opacity: 100 ! important; to the CSS style sheet. You can see that the top opacity: 0 is disabled, which means opacity: 100 is displayed first.
