When working with vendor prefixes, it is important to put the vendor prefix versions of a property first and end with the non-prefixed version.
This way, older browsers that only support the prefixed property will use the prefix, but new browsers that support both prefix and the non-prefix versions will use the non-prefixed standard version.
Add the highlighted prefix appearance properties as formatted in the following code block:. The appearance properties have removed the embellished styling and have gone to a simpler style, as rendered in the following image:.
The appearance property only allows you to change the browser-specific styling. The biggest change the appearance: none property value made was to remove the radio buttons and checkbox completely. For the rest of the form elements, a few more properties are needed to completely remove the default styles. The highlighted CSS properties in the following code block add the necessary styles to remove the default styles:. This CSS removes the background color and resets the parameters of the box model.
Not all of these styles are necessary for all the elements, but it is acceptable to group these reset styles across all the elements. The form elements have visually disappeared from the page, as shown in the following image:. In this section, you used appearance and additional properties to completely remove the default styles from the form elements.
You also used vendor prefixes to appropriately order apply the property for future browser versions. In the next section, you will begin customizing the visual styling of the form fields.
Now that the default browser styles have been completely removed, you will apply a consistent custom aesthetic across all the form elements. This will involve creating various group selectors that target specific form characteristics to receive the appropriate styles. Then, create a group selector consisting of input , select , and textarea. Add the highlighted styles from the following code block:. These styles add a 2px dark gray border around each of the data entry elements, along with a white background and rounded corners.
Next, you will apply styles for the data entry elements that contain text inside. You will use an attribute selector to specify which input elements to target based on their type attribute value. The highlighted CSS in the following code block provide the styles for the necessary elements:.
These styles apply a consistent font size and family across all elements. The display , box-sizing , width , and padding properties provide a consistent layout and structure for each of these data entry elements. Return to styles. Inside the selector block, create a min-height property set to a value of 10rem. This will create a larger initial area for the form user to fill in text.
The highlighted CSS in the following code block illustrates how this is written:. After adding the styles for the textarea , the next thing to accomplish is to make an image directory. That can be done by running the following in your command prompt from within the same directory as your index.
Next, run the following curl command to download the first image you will work with into the new images directory:. Then, create a select element selector and add a background property with the highlighted value from the following code block:.
Then it centers the image vertically with center and offsets it from the right side with right 0. The following image illustrates how this is rendered in the browser:. In the next section, you will create custom radio buttons and checkboxes and apply selected states when they are checked. Start by opening styles.
You will change the input elements with a type attribute of radio or checkbox to have an equal height and width value. Then you will turn the radio buttons into circles. The highlighted portions of the following code block show how this is formatted:. The vertical-align property is meant for aligning inline text items. By setting this to middle , the input fields will sit in the middle of the text align. The two radio buttons and the checkbox are now larger and more noticeable as rendered in the following image:.
If you were to interact with the radio buttons or checkbox, nothing visible would happen. The appearance property also removes the selected indicators for these types of input. Next, you will use the :checked psuedo-class selector to apply styles to the selected input item. Then, inside the selector block, add a background-image with a radial-gradient so a filled-in style can be applied to selected radio buttons. The highlighted CSS from the following code block shows how this is formatted:.
The calc function allows the transparent property to be set 1px after the color value, creating a solid blue circle inside the input field. The radio buttons now have a solid blue circle surrounded by white inside the input.
The following image shows the Yes radio button selected:. Run the following curl command to download the checkmark image to your images directory:. Now that you have the image downloaded and ready to use, return to styles. In the selector block, add a background property that loads the check. The highlighted CSS in the following code block indicates how this is written:. When selecting the Receive our newsletter check box, now a checkmark appears inside, as illustrated in the following image:. In this section, you created custom radio buttons and input fields and made them adjust their selected state through the use of the :checked pseudo-class.
There are two different styles that will be used: a small label style for the radio button and checkboxes and a large label style for the remaining elements. Open index. Save these additions to index. In styles.
These styles set the large-label elements to be large and bold with a font size of 1. Then the margin-bottom property provides some space between the label and its counterparts. Save this change to styles. The label text above the data entry field will be large and bold, as rendered in the following image:. Since these are the labels that are to the right of a radio button or checkbox, they will need some different spacing and sizing styles compared to the.
