Step 1 – Create new html document code
In the above screenshot you can see that I have created a basic html document. That contains the root “html” tag and the “head” and “body” tag.
Step 2 – Create a basic select dropdown with a few options
In the above screenshot you can see that we have created a select element using select tag with 3 basic options.

In the above screenshot you will see the expended select dropdown element. Which has 3 basic select options.
Now let’s manipulate the dropdown arrow of the select option using CSS.
Step 3 – Add necessary CSS style to hide default select dropdown arrow
In the above highlighted section of the screen shot, you will see that I have added 3 CSS properties in the select tag body.
The first one is the general property which hides the dropdown arrow. And the second property is “-moz-appearance” to hide the select arrow on Firefox web browser.
And the third one is “-webkit-appearance” to hide the select dropdown arrow on Safari and Chrome web browsers.
Now let’s render this code in our web browser to see the effect of the css style.

Now let’s render it to the web browser to see our changes in the web browser.

Step 5 – Add background arrow image using CSS
In the above screenshot you will see I have added 4 properties.
- First property sets the background image via the url of the image.
- Then the second property is to control the repeat of the background image. With this property our image will not be repeated to the x and y axis to the element.
- In third position I have added a background position property that controls the position of our dropdown arrow image. The first value is a calc function that controls the x axis position of the image and the second property is the center that controls the y axis position of the image.
- The Fourth property is the image size. I have adjusted the background image size according to the need.
Now let’s render it in the web browser and see our final results.
