Adjusting the layout of a webpage using CSS

I am facing a challenge where I need to adjust the layout of a webpage using CSS for mobile view. Currently, the desktop version has a sidebar floated to the left and a textbox floated to the right. The HTML structure is as follows:

<div id="container">
   <div id="sidebar">...</div>
   <div id="textbox">...</div>
</div>

My issue arises when it comes to displaying this content on mobile devices. I want the sidebar to appear below the textbox for better mobile usability, but I am having trouble figuring out the necessary CSS code to achieve this. I have been using media queries to target smartphones like so:

@media screen and (max-width:479px) {
  /* Target portrait smartphones */
}

If anyone can provide me with the correct CSS solution for this problem, I would greatly appreciate it. Thank you in advance.

Answer №1

To achieve this, simply follow these steps:

<div id="container">
   <div id="textbox">...</div>
   <div id="sidebar">...</div>
</div>

Place the textbox first in order to eliminate float for mobile devices. Therefore, prioritize the textbox followed by the sidebar.

Apply the following CSS:

.textbox {
    width: ***px;
    float right;
}
.sidebar {
    width: ***px;
    float left;
}
@media screen and (max-width:479px) {
  /* Target portrait smartphones */
  .textbox, .sidebar {
     float: none;
  }
}

I hope this explanation is helpful! :)

Answer №2

To optimize the layout for mobile devices, it is recommended to place #sidebar after #textbox in your HTML code. This adjustment will not impact the desktop view. Additionally, you can easily remove the floats for both elements on mobile screens using the following CSS media query:

@media screen and (max-width:479px) {
  #sidebar, #textbox {
    float: none;
  }
}
