There are a few slight differences in how we name CSS files and how we use classes in React that are demonstrated in the code above:.

The next approach to changing the background color in React is to write all of the CSS styles inline. Ironically, this was not a good approach for many years, with developers favoring the external CSS file method for ease of use and readability. In recent years, there has been a resurgence of writing inline styles, or CSS-in-JSdue to its flexibility and control. Therefore, we can write a conditional that passes in the name of a CSS class depending on the value of a variable!

In the example above, we set isBackgroundRed to true. The inline conditional checks whether isBackgroundRed is true. There we have it. An in-depth tutorial on changing the background color! Your email address will not be published.

Did you know that your browser will automatically add some CSS styles to elements without you ever specifying them? It's true! The most common case is when elements have focus, and in this tutorial we'll look at how you can specify your own styles in those cases. Let's visualize the problem first. Different browsers do different things when elements get focus. Before we force consistency, let's take tour of what browsers do in the two most common focus-related scenarios: form elements and hyperlinks.

The most common area you encounter focus visual changes is with form elements. For example, I have a text field that appears with a thin blue border normally:. As you can see, what used to be a thin blue border becomes something more pronounced.

Other browsers such as Chrome do something similar:. Instead of a blue outline, you see something bolder in orange instead. Again, this is something you never specified. Your browser did this automatically for you. If I give my text field focus in Firefox or Internet Explorer, they don't do anything different.

They just have focus. You probably get the picture, but focus issues don't just affect form elements. Different browsers do something different when a link has focus as well. I wasn't able to give a text field focus in Safari, but I am assuming it will be displayed in the big blue outline.There is no onHover event handler in React.

When it comes to React event handlers and onHover: The onHover event handler does not exist in React. Therefore, React has provided the following event handlers for detecting the hover state for an element:.

Showing or hiding something is a fairly common UI pattern when hovering over another UI element. Then, we conditionally render a div below the button using the isShown variable. We do this by adding onMouseOver to the button element. After declaring that this element has an onMouseEnter event handler, we can choose what function we want to trigger when the cursor hovers over the element.

We declare a function called changeBackground above the view part of the React Component. The changeBackground function receives the event object which is passed automatically through any event handler to a functionand changes the style. Save this component, jump over to your running React app in your browser and hover over the button. There are two additional hoverable event handlers in React, one of which is the onMouseOut event handler.

When an event bubbles, it moves, or propagates, up the DOM hierachy. If we use the onMouseOut event handler, anytime the mouse cursor leaves a decendant of that element, the event would trigger. Your email address will not be published.

In React Native, how do you change the style of a textInput when it gets focus? Say I have something like. This documentation leads me to believe that the solution is something like. Ignoring potential mistakes in the styles structuring, would this be considered correct way to handle it? It seems very verbose to me. You can achieve this by passing in the onFocus and onBlur events to set and unset styles when focused and blurred:.

I've set up a full working project here. I hope this helps! Felix gave me an idea that might be perhaps even cleaner. I would have loved to not have included state though on this static component, just to change styling But I am to new to this to figure that out.

I added the style into an array, have all the actual input styling done on the first property of the array and the second one the nit picking of the focus and blue. You can of course avoid creating a wrapper but if you have more than one input it will create a mess in your input s parent components as you will have to add repeating logic. Learn more.
