While developing a WordPress template for ane of my friends, he asked to have a business form over a transparent background. Though his sentence framing was not clear, his intention was to show the HTML form over a moving banner with a semitransparent background. If the course only displays over an image, information technology will create readability issues. He knows, users will non use the form with readability issues and that is why he wants a semi-transparent background which will not disturb the beauty of moving banner merely at the aforementioned fourth dimension make the grade readable. This tutorial explains the steps to create a semi (if yous desire, fully transparent ) groundwork on HTML pages using CSS. Have a await at the form below.

This is a simple concern form created using HTML and CSS. All information technology does is to collect visitors business name, email address, phone number and the real name. Though it is a uncomplicated form, some users find information technology irritating as the groundwork epitome is a distraction while filling the class. By setting a semi-transparent background in CSS, we can make this class look better. To meet the deviation have a look at the image below.

How to Place a Semi-Transparent background layer behind a Form

The logic is very unproblematic.

Create a DIV which cover the course
Set the groundwork colour to the DIV
Prepare Opacity

Note: While giving background-color, yous must utilise RGB format. If you use HEX color code, the opacity will be applied to the grade, not to the groundwork.

</form>

</div>

In the DIV 'bannerform' we must use the following code.

background: rgba(255, 255, 255, 0.4);

Here I use 0.4 of opacity out of 1. If 1 is used instead of 0.4, you lot tin can meet a white background.

background: rgba(255, 255, 255, 1);

See what happens if nosotros use opacity 1.

See the departure? The entire DIV background becomes white. Note the point rgba(255, 255, 255) is equivalent to #ffffff which means white colour. If you want to set the semi-transparent green color you should use the below code.

background: rgba(0, 255, 0, 0.4);

If it is blue instead of white and green, the RGB code is,

background: rgba(0, 0, 255, 0.4);
